     The present device relates to electric systems using cable which is employed throughout the world for communication of electric wires from a buss to individual outlets and connections, as well as communications and other cabling systems. More particularly, the disclosed device and method relate to a cabling system including both electrical and/or communications wiring in concert with an adjacent fluid conduit employable for communication of a fire ignition suppressant fluid or gas such as Halon or a clean agent or inert gas, through the entire cabling system between a main panel and junction boxes and electrical connection points along the conduit system. 
     BACKGROUND OF THE INVENTION 
     Electricity delivery systems in buildings in the U.S. and most of the world have evolved for safety and servicing reasons to employ metal or polymeric conduits, which provide a pathway therethrough for electrical wiring. Such wiring is employed for carrying current from a buss to individual sockets and connectors for equipment requiring electrical power and in other configurations for communications cables running between points. Running the electric and other wiring through a system of conduits protects it from wear over years of use and additionally provides access to retrofit or run new wiring subsequent to the completion of the walls of a structure which will encase the wiring therein. Such conduit in some instances is employed for shielding the contained wiring from EMF which can be generated by wires carrying electricity and electrical signals. 
     Electricity is conventionally run in individual circuits from a connection to the grid, through a circuit breaker connected to a central buss or other main connection. From the circuit breaker connection to the central buss, the electric wiring extends in a circuit to one or a plurality of remote connectors to which equipment requiring electricity engages. Such circuits may include junction boxes and other connectors downstream. By junction boxes is meant any box or mounting component adapted for joining wires or engaging sockets or distributing electric power or lighting or any electrical box used for any such purpose. 
     The connection to components using electricity conventionally engages the appliance or device requiring electrical power, to the circuit, using sockets and junction boxes and switches which can also connect with light fixtures and other components of conventional electric systems. For safety reasons, each individual electrical circuit is conventionally wired to carry electricity at a particular amperage load that the equipment or devices anticipated to connect to the circuit will require during use. This is generally accomplished by increasing or decreasing the diameter or size of the wires running through the electrical conduits for larger or smaller current requirements for the equipment connecting to the respective circuit. This wire size requirement is also adjusted by the distance the circuit will travel from the connection to a circuit breaker at the main buss or junction box. 
     A circuit breaker or fuse conventionally connects each circuit to the buss which is engaged to the power grid. The circuit breaker is generally sized to trip or open, to open the circuit should the amperage load, being drawn by equipment connected to points along the circuit, exceed the designed electrical load of the wiring for the circuit. Thus, the circuit breaker supplying a circuit will have a maximum amperage rating that will cause the circuit breaker to open should the electric load being drawn by equipment engaged to that circuit exceed the amperage rating of the circuit breaker. 
     This safeguard, designed into electric systems, is an important factor in preventing circuit overload and resulting fires which such can cause. In many instances an electrical fire caused by a circuit drawing excess electric current can be catastrophic such as in a high rise building, a hospital, or on a ship far from port where a fire can threaten the lives of all aboard. 
     However, even the best designed electrical system is not a total safeguard from an electrical fire caused by circuit overload, resistive heating at junctions or sockets, loose connectors, sparking, over voltage, or damaged electric lines and the like. For example, loose connections at a socket or wire connection in a junction box, will not cause an overload of current which will trip a circuit breaker. However, loose connections, along with over voltage situations, can generate resistive heating and in some cases sparking, which can easily ignite adjacent flammable materials in walls and ceilings and the like. 
     Further, over time, by accident or design, circuit breakers can be replaced with replacement breakers having amperage ratings exceeding the circuit they supply. Such can easily occur during maintenance when a circuit breaker is replaced with one of higher amperage due to the installed circuit breaker constantly tripping. While electricians would not make such a replacement, untrained personnel, owners and tenants, are well known for implementing such a fix. 
     Installing circuit breakers which have current ratings which exceed that anticipated in the circuit, can easily result in resistive heating of wiring along the circuit in places hidden from discovery such as in within conduits or junction boxes. This is caused by the circuit feeding electricity to more equipment on the circuit with a sum amperage being used which exceeds that for which the circuit was designed. 
     Further, loose connections along the circuit which cause resistive heating to occur during normal operation with the correct breaker engaged in the circuit, will emit heat which is significantly increased should the circuit draw more current than the maximum design. Such resistive heating and even sparking frequently occurs in junction boxes where multiple wires are engaged by wire nuts, terminal blocks, or in boxes housing electrical sockets and the like. 
     Additionally, connectors such as sockets and switches can over time become damaged or loose from the wire supplying them, or engaged in a manner which causes heating within the conduits and junction boxes. Again such occurs out of sight by users and inspectors, but adjacent flammable wood or plastic or insulation materials in walls and floors which become pyrolyzed from continuous or instantaneous overheating will have a reduced ignition temperature. 
     Such overheating of wiring in a junction box, or wall box holding an electrical socket or switch can thus easily become an ignition source and the cause of a fire. This is especially dangerous, since with the heat generated by loose connections or wires running electricity exceeding the wire capacity, continues for the duration of the ongoing communication of electrical current to the circuit. Thus, not only does the wiring become hot enough to ignite the insulation covering the wires, or the walls, ceilings, floors, and other adjacent flammable materials, this heat continues as long as the circuit is powered, and even after a fire has erupted in most cases leading to faster fire spread. 
     Of course, such an ignition source and resulting fire is hidden and extremely hard to initially detect and just as hard to extinguish once discerned. Thus, the risk of fire ignition and passage through interior wall cavities from overheated electric circuits and the like, is not readily apparent to a layman, but is well known to those in the business of electrical fire safety. 
     Often, as employees and firefighters do not have access to such relatively small spaces in order to view and discern flames, and to extinguish the flames, as typical water suppression systems are not supposed to be applied to electrically generated fires as that can pose additional fire safety risk for first responders or inhabitants trapped by the fire and the resultant fire spreads. Consequently, these fires can spread easily and quickly, even through structures constructed of fire-resistant material. Such a fire can ignite in the cable or wiring itself in a wall or ceiling if it becomes overheated or has been damaged by abrasion, rodents, lighting, or by other means where it can be exposed or slightly cut. Such fires can ignite in a junction box of a socket or where multiple conduits connect in a wall, to become a raging inferno and spread quickly from the ignition source by traveling through interior spaces of the ceiling or walls. 
     Still further, in these modern and uncertain times, fires in wiring between circuit breakers and junction boxes can be ignited by an electromagnetic pulse caused by nuclear detonation of either a conventional or what is known as a “dirty” bomb. Such an electromagnetic pulse occurred in Hawaii, decades past when testing by the military detonated over the Pacific Ocean, and could easily occur again in this uncertain world. One such occasion, the copper conductors of all conventional cable wiring systems can instantly overheat which could/would lead to insulation degradation and fire. Such for example can occur as a result of directed energy weapons. 
     While such potential from overheated circuits of all kinds is dangerous in homes, the risk of harm and loss of life is significantly higher in commercial establishments, high rises, and especially in airplanes, space ships, container ships or cruise ships, since a fire on the open sea in such metal ships spreads quickly and can cause massive loss of life. 
     Accordingly, the ability to confine an electrically ignited fire to a single room or area, may depend upon the ability to preclude its travel through walls and electrical fixtures, or to accelerate to a larger fire subsequent to ignition. Although previously described conduit systems and fire-proof and fire-resistant junction boxes are formed of materials meant to resist the flames, conventional conduit style electric wiring systems provide no means to extinguish a fire, once ignited in the circuit or in wall or ceiling or other space adjacent thereto, or in a junction box where such cables engage other cables or sockets for appliances. While the noted, use of conduit for communication of electrical wiring through buildings and ships and aircraft provides a pathway to contain the wiring, the heat and smoke generated therein easily escapes to the surrounding area and initiates fires. 
     However, conventional wiring and infrastructure systems provide no concurrent and jointly communicating pathway for the communication and activation of fire suppression chambers, and suppression devices and components. Instead, such fire suppression materials must be brought to the source of an electrical fire from a remote position such as a fire extinguisher. Such takes time by the time a wall-hidden or conduit-hidden fire is ongoing but first detected. This time wasted, in seeking out a fire suppressant supply and communicating it to the exact location of the previously hidden electrical fire, gives that fire time to spread even further or significantly intensify due to continued electrical heating, where the resulting flames travel through walls and conduits of the structure. 
     As such there is an unmet need for a cabling system and method configured to route both wiring of electrical circuits in parallel adjacent pathways and through junction boxes and the like, which concurrently allows for positioning of a fire suppression chamber and supply system proximate to any potential fire generated in a conduit or wall or structure. Such a cabling device and method, in addition to providing suppression at or proximate to the point of any hidden or viewable electrical fire, should allow for concurrent positioning for a fire suppression pathway and suppression chambers along and adjacent each circuit of electrical wiring. Such a system should also provide site specific fire suppression components positionable in junction and access areas and adjacent electric wires in the conduit system, which will automatically deliver fire suppressant to an overheated circuit. Such a cabling system when employed for fire suppression should also, once activated at a position along the conduit system for electrical wiring, provides a means for cutting electrical power to the individual circuit which has overheated and for signaling and alerting employees and emergency personnel of an overheated circuit or fire caused by one, even where that fire is not yet viewable. 
     The forgoing examples of related art and limitation related therewith are intended to be illustrative and not exclusive, and they do not imply any limitations on the invention described and claimed herein. Various limitations of the related art will become apparent to those skilled in the art upon a reading and understanding of the specification below and the accompanying drawings. 
     OBJECTS OF THE INVENTION 
     It is an object of the present invention to provide a cabling system and method, which includes a concurrent installation of both electric circuits and a fluid conduit and suppression chambers, adapted for supply by centrally supplied fire suppressant circuits, which are communicable in concert with the electrical wiring pathway from a circuit breaker buss to and through each junction box and housing along the path of each electrical circuit. 
     It is an additional object of the system herein to provide for suppressant-delivering components such as suppression chambers which are engageable with the fluid tubing along a fire suppressant pathway running adjacent or coaxial with the electrical conduit, which will self-activate to communicate fire suppressant to a circuit which has overheated due to resistive heating automatically. 
     It is an additional object of the cabling system and method herein to provide means to alert the user of a fire or resistive heating or sparking in an electric circuit, even where hidden by walls or conduits, along with the concurrent automatic release of fire retardant to the source of the resistive heating or sparking. 
     It is yet another object of the present invention to provide a cable having a fluid conduit and wires which is thereby configured for concurrent routing of electrical wires and a fluid pathway for fluid delivery such as a flame retardant material. 
     It is yet a further object of this invention to provide such a cable system which is configured to extinguish fires from sparking and resistive heating and the like in any electric circuit between junctions, as well as sense activation of such a fire suppression and concurrently cut electrical power to that circuit. 
     These and other objects, features, and advantages of the present invention, as well as the advantages thereof, over existing prior art, which will become apparent from the description to follow, are accomplished by the improvements described in this specification and hereinafter described in the following detailed description which fully discloses the invention, but should not be considered as placing limitations thereon. 
     SUMMARY OF THE INVENTION 
     In accordance with the purposes of the present invention, as embodied and broadly described herein, the present invention provides a system and method which includes a cabling system enabling the adjacent concurrent routing and proximal positioning, of both wires carrying electricity and a fluid conduit or tube. The tube or conduit for fluid flow, can be configured to automatically dispensed fire suppressant, within the conduits, junction boxes, and other components of an electric wiring system for communicating electrical power. The tubing or conduit providing fire suppressant circuits of the cabling system are configured to run along the same pathways through a structure as the wires and electrical junctions of an enclosed electrical system circuit. Employing the cabling and connectable components herein, both the electric wiring and fire suppressant system may be installed concurrently during construction of the structure or vehicle, where the electric system is installed. 
     The system herein provides an electric cable surrounded by a sheath or cover which also includes a tubing or conduit pathway for communication of fluid or gas along the electric pathway of the cable. The cabling may be thus employed in one mode for delivery of a pressurized fire suppressant supply, which runs within or in combination with and parallel to the electric wiring in an electric conduit pathway for wiring. Some of the further components employable with the cabling system herein for fire suppression, include for example, suppressant chambers, junction box-housed fire suppressant dispensers, which are proximate to the positioning of electric wires joined in a circuit or which communicate in connections to sockets or connectors in a junction box which in turn connect to electricity-consuming devices. 
     The system includes retardant dispensing components adapted for engagement to the fluid conduit of the cabling, which are configured for operative positioning in engagements within or to junction boxes, sub-panels, and socket or connection boxes, light fixture mounts, and the like. The dispensing components are configured to engage electric sockets and connectors as well as junctions between wires which enter or exit therefrom. The fluid conduit itself is formed of a material adapted to melt at a temperature indicative of a fire or overload from resistive heating and dispense suppressant at locations in between the circuit buss disconnect assemblies, and junction boxes. 
     Connections between fluid conduit or tubing and dispensing components in one preferred mode of the system, employ circular junction points although alternative configurations can optionally include specific terminal male or female connectors for easy disassembly and access. The junction boxes having retardant dispensing components operatively mounted therein or thereto, may also include sub panel breakers and busses, and/or sockets engageable with appliances or lighting or other devices consuming electric power. 
     To inhibit the spread of electrical fires, the junction box and other inter-connecting components for connecting and routing of electric circuits, may additionally contain or have attached, a suppressant dispensing component such as a suppressant chamber, capable of holding a reservoir and releasing a specific volume of fire retardant material into the housing or junction box or the like. The tubing or fluid conduit of the cabling herein, can supply this fire retardant from a central source also, or in some systems charge each such suppressant dispensing component or chamber forming a local reservoir, and communicate additional suppressant from a central or remote source at a distal end of the fluid conduit. 
     In the preferred mode of the device, the suppressant chamber, when operatively engaged with the fluid conduit, can be composed of a thin housing, which can be ruptured by impact, or which is configured of a thickness and of a material which will melt or open when exposed to a temperature level, indicative or generated by a fire or from overheating caused by resistive heating in wiring, prior to an ignition of a fire. The device should be configured for the fluid tubing or conduit of the cabling to engage and accommodate and dispense fire retardants which are either gas or liquid at room temperature such as Halon, and to provide a continuous or a specific volume communication of such to a locale until turned off. 
     Additionally preferred, junction boxes for electrical wires and sockets and the like, may contain two or more suppressant ports, configured to engage with the fluid conduit of the cabling to draw retardant material from multiple sources, such as nearby junction boxes, for increased fire fighting capability. 
     It is preferred in one mode, that a dispensing component such as a suppressant chamber or port include a visible viewable suppressant window, thus allowing for visual confirmation of the presence of a retardant supply therein. The suppressant ports or suppressant chambers can additionally contain one or a combination of fire and retardant activation sensors from a group including heat sensors, microphones, pressure sensors, dyes, color reactive films, accelerometers or contact switches. 
     One or many flow sensors attached to the fire suppressant buss supplying the fire suppressant to fluid conduit of the cabling, or embedded within the suppressant ports or at locations on the fluid conduit, can also be used to detect a suppressant chamber rupture or a dispensing of retardant, and to send a signal to a central monitoring station, and/or to the circuit breaker supplying the individual electric circuit, to turn off electric power. Additionally, weight measurements can be monitored of fire suppressant tanks and should the weight of the tank drop, the electrical power can be disconnected. 
     The sensor data can either be displayed proximal to individual suppressant component positions of the system, or through an external light or viewing screen, or viewing window. Such data might also be routed as an electric or preferably wireless signal to a central panel for efficient and simultaneous monitoring and diagnosis of all devices running along individual tubing pathways in the system. Remote display panels should contain means to uniquely identify the retardant tubing in relation to the circuit it supplied to each junction box by description or identification number. 
     In another or second preferred mode of the device, a local supply of the retardant material may be stored within the suppressant chamber and as such, the suppressant chamber formed as part of or engaged with the junction box, may dispense retardant which may be supplied or replenished by a conduit connection to the suppressant tubing system. All or at least portions of the suppressant chamber should be formed of material, such as HDPE, pfa, nylon or similar polymeric material. 
     The cabling herein, in all preferred modes, is configured to include and route one or more electric wires, and at least one adjacent fluid conduit, both of which are surrounded by an outer jacket or sheath. This configuration of both wiring and fluid conduits within an axial passage of a surrounding jacket or sheath, allows for easy concurrent installation of both a suppressant carrying conduit for gas or fluid, and electrical wires, in a manner similar to the conventional installation of wiring cables such as ROMEX or shielded cabling. When the fluid conduit is configured to carry fire suppressant, all or portions of the fluid conduit may be formed of material adapted to melt or rupture upon reaching a temperature indicative of fire or overheating from resistive heating or sparking. Thus, the same cabling provides for communication of fluid or gas flame suppressant supplies to all points on the installed electric cable system, from the circuit breaker to all points along the circuit. 
     In one preferred mode of the device, where suppressant is supplied from one end, the cabling includes a sheath or flexible jacket surrounding the electric cables and a fluid conduit which may include a series of perforations in the sheath. These perforations have been shown in experimentation, to allow for trimming during installation. Further, during testing unexpectedly it was found that the perforations or apertures also provided pathways for the dispensing of fire retardant material, to areas surrounding the cabling, should the tubing or fluid conduit carrying the retardant, be exposed to fire or heat within a wall which is of a temperature which will melt it. Additionally, one or a combination of currently available electrical protection devices can also be employed within the junction box for additional protection from a group including surge protectors, dedicated fuses, arc fault protective devices, and ground fault intercepts. 
     When the cabling herein is employed in forming electric circuits, the junction boxes or gang boxes and the like, should be composed of one or a combination of durable fire resistant materials such as metal, aluminum, code-allowed plastic, fiberglass, glass or ceramics. The fluid conduit of the cabling should be made of one or a combination of polymeric materials, which are non-reactive from a group including polymeric material, plastic, nylon, PVC, polyethylene, or fiberglass or other material which is inert in the presence of the fire suppressant carried within. 
     Particularly preferred is the employment of High-density polyethylene (HDPE) for the fluid conduit included in the cabling. HDPE has been shown in most indoor installations of the cabling herein to be superior as fluid conduit to supply retardant. This has been found to be due to HDPE&#39;s ability to maintain its structural integrity when exposed to heat below that of fire or potential fire over long periods of time. HDPE, pfa, nylon or other similar materials have a melting point of substantially  400  degrees Fahrenheit which enhances the ability of the fluid conduit to stay strong and resist melting when adjacent to electric circuits which can naturally heat daily during use. 
     For example, a common electric wiring insulator material is PVC which melts at a first melting temperature which is substantially at 320 degrees Fahrenheit. As such, the material for the fluid conduit should preferably stay intact and not rupture or leak to a second temperature, beyond the first temperature of 320 degrees Fahrenheit, which the wires might reach, carrying a high current load. Thus, nylon with a melting point between 400 to 500 degrees Fahrenheit, or High Density polyethylene, with a melting point substantially at 400 degrees Fahrenheit would be good choices to maintain the fluid conduit intact, unless the circuit or area goes beyond a possible operating temperature where a fire or potential fire is present. In all modes of the device herein, the melting temperature of the fluid conduit, or the second melting temperature, should preferably be above a first melting temperature of the insulation on the electric wires. 
     However, once the temperature threshold is reached due to overheating of the circuit such as from resistive heating, sparking, or fire, the fluid conduit will rupture and provide suppressant directly at the source of the fire anywhere along any circuit path allowing for purging of conduits systems, concealed wall spaces or within dedicated enclosure assemblies. 
     Other non metal materials used for the fluid conduit during experimentation, showed signs of softening when exposed to heat over time at temperatures below that which might be considered dangerous in some instances and thus could cause leaking and fire alarms where none are present. Thus, system reliability in longer term installations, and where electric wiring carries current causing normal but ongoing heating, HDPE or nylon would be more preferable for use in the fluid conduit of the cabling when supplying fire suppressant and used with wiring carrying conventional PVC insulation. However, the material for the fluid conduit can be changed or adjusted such that it will fail and release the fire suppressant at a temperature higher than normal operating circuit temperatures. 
     The cabling system herein is described for the provision of cabling having both electric wires and a fluid conduit for supplying fire suppressant to allow for the easy installation of a combination wiring system and fire suppressing system during construction or retrofit of a building or structure. The cabling of the system herein would be especially useful to protect cruise ships, hospitals, nursing homes, airplanes, submarines, museums, data centers, banks, underground bunkers, as well as the noted use in buildings, businesses, restaurants, and residences, or in any situation where one skilled in the art would consider the ability to automatically sense potential or actual electrical fires and extinguish them. 
     However, using the uniquely configured cable herein having both a fluid conduit and electrical wires in the same installed cabling component, the cabling can also be employed for other uses where electrical wires along with a fluid conduit would be beneficial. Such could include, but should not be limited to, outside power distribution circuiting, either over roof tops, or in desert (solar farm) style applications, for production plants, in areas of weather having high heat for carrying electricity, and other installations. In these modes, instead of fire retardant or suppressant being charged and delivered by the fluid conduit of the cabling, fluid conduit can be charged with a non conductive coolant, glycol for example, which when flowing though the system can help with heat dissipation. 
     Additionally, the cabling herein would be helpful in very hot environments, where an engineer must de-rate (increase the size) of the conductors employed for carrying electric current to account for over heating due to ambient temperatures. Using the cabling herein with the unique combination fluid conduit and electrical wiring running adjacent, the user can employ the fluid conduit to flow the fluid to cool the circuits. This could eliminate the expensive de-rating of wiring due to outside or environmental ambient impacts. 
     Still further, in another mode, components such as lamps could have small canisters of fire retardant mounted within the assembly and trance the power circuit using the fluid gas line from strain relief up to light socket in combination with a simple locking switch, to either directly short the conductor to cause a breaker to trip or open should the canister release. 
     As such, before explaining at least one preferred embodiment of the herein disclosed invention in detail, it is to be understood that the cabling invention is not limited in its application to the details of construction and to the arrangement of the components in the following description or illustrated in the drawings which primarily are directed to the use of the combination fluid and electrical conduit in buildings, structures and vehicle for fire suppression. The cabling system herein described and disclosed in the various modes and combinations is also capable of other embodiments and of being practiced and carried out in various ways which will be obvious to those skilled in the art. Any such alternative configuration as would occur to those skilled in the art is considered within the scope of this patent. Also, it is to be understood that the phraseology and terminology employed herein are for the purpose of description and should not be regarded as limiting. 
     As can be discerned, those skilled in the art will appreciate that the conception upon which this disclosure is based may readily be utilized as a basis for designing of other systems of cabling with concurrent and adjacent positioning of electrical circuits and at least one fluid carrying conduit. It is important, therefore, that the claims be regarded as including such equivalent construction and methodology insofar as they do not depart from the spirit and scope of the present invention.

     DETAILED DESCRIPTION OF THE INVENTION 
     Now referring to the drawings in  FIGS. 1-40 , wherein similar components are identified by like reference numerals, there is seen in  FIG. 1 , and other drawings where components are configured for operative engagement with the cabling  11  herein, to provide one or a plurality of wires and at least one fluid conduit, in the same cable  11  surrounded by a sheath  24  or cover. As noted, the cable  11  herein is employable with other systems where the parallel and concurrent positioning of both a fluid conduit  26  and electric wires  28  along the entire path of the same cable  11  would be beneficial. 
     As shown in  FIG. 1 , when the cable  11 , such as in  FIG. 3  or  FIGS. 8-17  herein, is employed to provide a combination electric wiring system and fluid passage for a fire suppressant system, the cable  11  is operatively engageable with other components in the system such as a junction box  12  or gang box or terminal box component, which is meant as any electrical box or the like used to join wires, engage sockets, lighting, sub circuits or for other purposes for such electrical boxes. The junction box  12  may be configured to house both electric connections therein such as to or between other wires  28 , and/or an electric socket  16 , and/or a fire suppressant component or chamber  18 , or other fire suppression fluid or gas emitter. 
     The cable  11 , when employed in a fire suppressing electrical system  10 , is deployable in a variety of configurations, such as with one or more gang boxes or junction boxes  12 , shown in  FIGS. 1 and 2 and 5 , for example. Such a junction box  12 , surrounds and secures the electrical connections between two or more of the wires  28  which enter or exit through one or more apertures defining openings  14 . 
     Such junction boxes  12  are known by other names and surround connections mid circuit and are also used for sockets, light fixtures, and a wide variety of connections. However, this description should not be limiting as junction box  12  should be considered to be any housing where cables are joined, divided, connected to an electric device, or for other purposes. Although the openings  14  shown herein in the system  10  consist of circular apertures formed in the junction box  12 , alternative constructions can optionally include specific male or female connectors for easy disassembly and access. 
     As an example, the junction boxes  12  may be configured to engage with conventional sockets  16  or switches  17  of electric fixtures, and/or wire  28  connections with wire nuts, terminal blocks, and other conventionally employed electrical components and junctions to configure the system for engagement of components to the electrical power within. 
     To inhibit the spread of electrical fires, in the system herein, junctions between conduits and wiring in the electrical system such as at any type of junction box  12 , may also include a suppressant chamber  18 . The suppressant chamber  18  is configured to receive and hold a supply of fire suppressant or retardant such as Halon gas from the fluid conduit  26  which communicates with a central supply under pressure. The suppressant chamber  18  holds such fire suppressant or retardant within an internal cavity defined by the walls forming the suppressant chamber  18 . The suppressant chambers  18  may be configured to hold a local supply of retardant therein, should the fluid conduit  26  supplying the system fail, thus maintaining a local sealed supply of retardant or suppressant in each chamber  18  if the fluid conduit  26  is compromised. This can be done using valves on the inlet  29  and an outlet  29  of the suppressant chamber  18 . Or the suppressant chamber  18  may be provided a fluid supply from the fluid conduit  26  which is communicated from a reservoir of suppressant. 
     The system  10  is configured such that any damage to the junction box  12  or its contents, through excess heat or fire, such as caused by electrical short or over-heated wiring  28 , will melt and cause a rupture of all or portions of the suppressant chamber  18 . Upon the formation of a heat induced rupture, the retardant or suppressant within or supplied to the suppressant chamber  18 , is communicated to the fire or overheating area. As shown, the fluid conduit  26 , can supply each suppressant chamber  18  and junction box  12 , with a continuous pressurized supply of retardant or fire suppressant which will continue to extinguish or prevent a fire from getting larger. As noted, all, or at least portions of the fluid conduit  26  itself, can be formed of material adapted to melt and rupture at a threshold temperature, and communicate the fire suppressant to adjacent areas anywhere the cable may be located in a wiring system, such as in-between junction boxes  12  and fixtures and a circuit breaker buss. 
     In one preferred mode of the system  10 , all or portions of the suppressant chamber  18  can be composed of material, such as HDPE, pfa, nylon or similar polymeric material with a wall thickness which is calculated to melt and or otherwise open when exposed to a temperature over a determined safe level or when exposed to fire. This will cause a continuous dispensing of fire retardant or suppressant to extinguish the fire, or prevent one, by preventing oxygen from reaching the heat source. With regard to the wall thickness, it can calculate to fail, due to the internal pressure within the suppressant chamber  18 , when heated to a point the wall will distend and fail. 
     Shown in  FIGS. 2 and 4 and 5 , the junction box  12  is adapted to operatively engage with the fluid conduit  26  either through a conduit opening  20 , or by communication of the entire cable  11  through an opening  14 . Each suppressant chamber  18  is configured for a sealed engagement with the fluid conduit  26  running through the cable  11  herein, to provide the suppressant chamber  18  with a fluid or gas suppressant supply. 
     For such engagement for example, the suppressant chamber  18  can be configured with one or a plurality of flanges  19  with axial passages into the interior cavity of the suppressant chamber  18 , which act as inputs or outputs for fluid to continue the communication of the suppressant through the chamber  18  to subsequent chambers  18  along a fluid circuit with connections therebetween by the fluid conduit  26  running through the axial passage  23  of the sheath  24  of the cable  11  along with the wires  28 . 
     Preferably, the junction box  12  should include a suppressant window  22  for visual inspection to confirm a local supply of retardant or suppressant is present within the suppressant chamber  18  which is viewable through the window  22 . 
     One or a plurality of flow and/or pressure sensors  31  may be placed in communication with suppressant axial passage  23  running through the fluid conduit  26  such as in  FIG. 7 . For example, sensors  31  such as pressure supply meters, flow sensors, or pressure sensors, shown in  FIG. 7  and/or other electronic sensors which may discern a pressure drop in a fluid conduit  26  circuit, can be operatively engaged with each fluid circuit which parallels an electric circuit running through a cable  11 . 
     The sensor data can either be displayed proximal to the system  10 , through an external light or screen, or routed to a central safety video display panel, for efficient and simultaneous monitoring and diagnosis of all systems  10 , or in a particularly preferred mode, such as shown in  FIG. 7  for example, a signal from the sensors  31  will be communicated in a wired or wireless fashion to a circuit breaker  33  powering the same wire or wires  28  running through a cable  11  with a fluid conduit  26 . The signal will cause the circuit breaker  33  to open, and switch off electric power to the wires  28  in the cable  11  of the circuit where suppressant is being dispensed and which has caused the sensor  31  to generate a signal. Remote display panels, if displaying a sensor signal generation, should contain means to uniquely identify the location and circuit of the sensor  31  generating it. Such a signal could be generated by a weight sensor  31  to allow the system to monitor the weights of the fire suppressant tanks and should the weights fall below a certain threshold, it can shut that circuit down as well. 
     Depicted in  FIG. 3  is one example of the cable  11  herein, showing the sheath  24  forming an axial passageway  23  which provides a pathway for one or more wires  28 , and at least one adjacent running fluid conduits  26 , as shown, although a plurality of fluid conduits  26  can be included in a cable  11 . 
     Formation of the cable  11  with wires  28  and a fluid conduit  26  running in an axial passageway  23  defined by the surrounding sheath  24 , allows for easy instillation of the cable  11  in a fashion much like conventional conduit routed electrical systems, thereby allowing concurrent positioning of both wires  28  and a fluid conduit  26  throughout the system. 
     As shown in  FIGS. 3, 10, and 15 , the sheath  24  may include an array of aligned apertures  32  which allow for easier trimming during installation. Further, these apertures  32  provide vents to communicate fire suppressant from the fluid conduit  26  if a fire or heat melts the fluid conduit  26  to a rupture in between junction boxes  12 . The fluid conduit  26 , as noted, should be made of any non-reactive, durable material such as polymeric material, nylon, PVC or fiberglass, or most preferably HDPE or PFA, which has a melting point which will cause a rupture the fluid conduit  26  at an appropriate temperature above the operating temperature of the wires  28 , to extinguish or retard a fire if needed. The flexible sheath  24  would also preferably be formed of a similar material to that of the fluid conduit  26 , such that it will not melt or rupture in areas where the fluid conduit  26  is also adapted to operate which may be hot. 
     Shown in  FIGS. 4 and 4   a  is a mode of the junction box  12  which is depicted with the suppressant chamber  18 , configured to engage and provide a removable cover for the internal cavity of box  12 . Such would work well at junctions between main and sub circuits of the electrical system. 
     In  FIG. 5  there is shown a gang box or junction box  12  configured for engagement of electric switches  17 . This mode of the junction box  12  is engaged with a suppressant chamber  18  with connections  29  on both ends, for the fluid conduit  26  for a throughput of suppressant supplied by the fluid conduit  26  through the chamber  18  and on to a subsequent chamber  18 . Windows  22  in the faceplate allow for viewing of the contents of the suppressant chamber  18 . 
     In  FIG. 6  there is depicted an example of the system  10  herein using the cable  11  for positioning of both electrical circuits of the wire  28  and fire suppressant circuits of the fluid conduits  26  running to remote positions from a main electrical connection buss and retardant supply buss. 
     Shown in  FIG. 7 , as noted above, shows the system where various circuits of the fluid conduit  26  of each cable  11  connect to a pressurized suppressant supply in a fluid buss. The fluid buss also allows for communication under pressure of one or both of a dye  61  or scent  63  to the fluid supply. The dye may be fluorescent or colorized otherwise easy to see and the scent should be one which is easily sensed by humans. Such will allow for easier maintenance of the system wherein small leaks can be determined by dye  61  on surfaces adjacent leaks, and even hidden leaks which cannot be seen can be detected by the scent  63  which would permeate surrounding areas. 
     The wires  28  for each respective cable  11  connect to one of the breakers  33  of an electric buss  35  portion as shown in the example of a combination electric and fluid buss shown in  FIG. 7 . Gauges  39  and/or sensors  31  are engaged to suppressant circuits of each fluid conduit  26  and will sense the current pressurization level in each such circuit formed by a fluid conduit  26  in a cable  11 . The fluid conduit  26  and wires  28  of each cable  11  are routed through the axial passageway  23  of the sheath  24  with the wires  28  therein, thereby providing parallel and concurrent communication of electrical power and fluid such as fire suppression along the entire route of each individual circuit of the electrical system. 
     As noted,  FIG. 8  shows the cable  11  herein having a fluid conduit  26  and a plurality of wires  28 , both positioned in axial passage  23  of a surrounding flexible sheath  24  holding the components of the cable  11  adjacent. In the mode of  FIG. 8 , the material forming the sidewall of the fluid conduit  26 , is engaged with the plurality of wires  28  during extrusion of the fluid conduit  26 . Thus, the fluid conduit  26  and plurality of wires  28  running through the material forming it, are a unitary structure of wires  28  and fluid conduit  26 . 
     In  FIG. 9  is shown the cable  11  or cabling herein configured with a fluid conduit  26  and wires  28  running through the axial passage  23  of the surround flexible sheath  24 . The cable  11  so formed, can be wound into rolls or spools which can be unwound and installed in a conventional fashion thereby encouraging widespread use. 
       FIG. 10  depicts the cable  11  herein in another mode with a plurality of three electric wires  28  and at least one fluid conduit  26  running axially through the surrounding sheath  24 . The wall of the sheath  24  includes aligned and sequentially positioned apertures  32  which as noted allow for easier cutting of the cable  11  as well as provide vents for passage of fire suppressant from the interior of the sheath  24 . 
       FIG. 11  shows the cable  11  of the system herein wherein the plurality of wires carried in the sheath  24  axial passage is four, and a single fluid conduit  26  runs parallel thereto. 
       FIGS. 12 and 13  show a mode of the cable  11  wherein electric wires  28  are positioned during extrusion within the material forming the fluid conduit  26 , and form the fluid conduit  26  and wires  28  in a unitary structure. 
       FIG. 14  shows that the cable  11  or cabling with a plurality of electric wires  28  as well as one or more communications cables  28 a which run within the axial passage of the surrounding sheath  24  along with the fluid conduit  26 . As with all other modes of the formed cable  11 , it can be wound on large reels and dispensed during installation. 
       FIG. 15  shows the cable  11  of  FIG. 14  having the sequentially positioned apertures  32  formed in the sheath  24  providing the axial passage for the fluid conduit  26  and wires  28 . 
     In  FIG. 16  is shown the cable  11  or cabling herein having an armored sheath  24  surrounding the axial passage carrying at least one fluid conduit  26  and one or the shown plurality of wires  28  for electric current. 
       FIG. 17  depicts the cable  11  or cabling herein, wherein the electric wires  28  are carried in the sidewall forming the fluid conduit  26  herein. As shown, the wires  28  may be pressed into channels formed in the exterior of the sheath  24  surrounding the fluid conduit  26 . 
       FIG. 18  shows differing connectors  31  for sealed engagement between ends of the fluid conduits  26 , allowing a number thereof to be fluidly engaged. 
     In  FIG. 19  is depicted a sliced view showing an interior passage of a fluid conduit  26  in a sealed engagement with a fluid connector such as any of those in  FIG. 18 . 
     In  FIGS. 20-21  are depicted exemplars of a sub panel junction box  12  of an electric system, which is adapted for engagement with both the wires  28 , and the fluid conduit  26  of the cable  11  herein, to provide electric power to the buss and fire suppressant to the fluid dispenser. The suppressant chamber  18  in the mode shown, has multiple inlet and outlet flanges  19  to allow the flow of suppressant to flow into and through the chamber  18  downline to the rest of the circuit. 
       FIG. 22  shows the cable  11  herein with the contained wires  28  and fluid conduit  26  of the cable  11 , in operative engagement with a junction box  12 , and fluid dispenser  18  engaged with a fluid dispensing sprayer  38  adapted to direct a downward flow of suppressant when activated by heat above a predetermined level. Such would be employed for example on a ceiling of a room to be protected. 
     Shown in  FIG. 23  is a depiction of the cable  11  herein, installed in a structure and providing both wiring  28  and a fluid conduit  26  which may be operatively engaged with a junction box  12  hosting a socket  16 , to provide fire suppressive material through the fluid conduit  26  to the depicted junction box  12  and a subsequent junction box  12  or other point serviced by the cable  11  extending therefrom. 
     An example of an installation of the system is shown in  FIG. 24  where the cable  11  provides the path for fire suppressive fluid for both socket connectors as well as overhead dispensers or sprayers  38  of fire suppressant, such as in a server room. The cable  11  may be any derivation of cable  11  shown and described herein as may the junction boxes  12  and other components. 
       FIG. 25  depicts a mode of the cable  11  for the system herein configured with romex type wires  28  running the axial passageway  23  of the sheath  24  surrounding the components of the cable  11 . The fluid conduit  26  having an axial passage  25  for retardant communication therethrough is shown running adjacent the wires  11  formed into the romex with all running through the axial passageway  23  of the sheath  24  which is shown with apertures  32  therein. 
     The cable  11  herein as noted may be configured to form the axial passage  25  therein or position the fluid conduit  26  having an axial passage  25  therein which runs axially through the cable  11 . This is shown in  FIGS. 26A-26C  which depict versions of the cable  11  employable herein wherein the wires  28  running within the axial passageway  23  within the sheath  24  are extruded or molded into in polymeric insulation material extruded to define sidewalls surrounding an axial cavity  27 . This axial cavity  27  itself may be employed for the axial passage  25  in substitute of a fluid conduit  26 , or as shown in  FIG. 26C  the fluid conduit  26  can run axially through the axial cavity  27 . 
     Another mode of the cable  11  employable with the system herein is shown in  FIGS. 27A-27B . As shown, some or all of the electric wires  28  may be engaged in a spiral wound or encircling winding engagement with the exterior of the polymeric material forming a fluid conduit  26 . This spiral winding has been found in experimentation to provide excellent phase separation to cancel out flux and minimize electric noise generation. The fluid conduit  26  so formed is provides the axial passage  25  for retardant communication through the system as needed. The wires  28  in this spiral winding or encircling engagement with the sidewall of the polymeric material forming the fluid conduit  26  may be co-molded therein or as shown, may be frictionally or adhesively engaged within slots  42  formed to wind around the exterior circumference of the fluid conduit  26 . The sheath  24  with apertures therein would surround the wire-encircled fluid conduit  26  in same fashion as in other modes shown herein. 
     Shown in  FIG. 28  is a mode of the junction box  12  which is configured to surround an electric connection such as a switch or depicted socket  16  within the cavity  13  surrounded by sidewall of the junction box  12 . In this configuration, a chamber  18  for holding a local supply of retardant fluid therein, is slidably engageable into the cavity  13  formed in the junction box  12 . As shown the chamber  18  has at least one connection  29  as an inlet for retardant into the chamber  18  and preferably has two connections  29  to allow a pressurized flow of retardant into, through, and out of the chamber  18 . A window  22  formed into the socket or switch cover allows for both a viewing of the chamber  18  for visual confirmation of the presence of retardant therein, and for disbursement of fire retardant from the suppression chamber  18  and into non concealed areas such as interior room space areas surrounding the junction box  12 , should temperatures in that surrounding area, reach the melting point of the material forming the chamber  18  within the area communicating through the window  22 . 
     In  FIG. 29  is shown a junction box  12  of the system herein which has the fluid chamber  18  engaged to form an upper portion and top sidewall of the junction box  12  wherein electrical connections such as to a socket  16  are positioned within the cavity  13  of the junction box  12  defined by the sidewalls of the junction box  12 . As noted above, by junction box  12  wherever used herein, is meant any housing employed in an eclectic wiring system wherein electric connections are made between wires  28  carrying electric current be those connects by wire nuts, crimping, electric receptacles such as a socket  16  or switch, or any other conventional electric connection positioned within the cavity  13  of the junction box  12 . 
     As shown in  FIG. 29 , in this mode of a junction box  12 , with the suppressant chamber  18  forming one sidewall of the cavity  13 , heat within the cavity  13  sufficient to melt the wall of the suppressant chamber  18 , formed as part of the junction box  12  and in communication with the cavity  13 , will cause fire retardant to flood the cavity  13 . Further, a projecting portion  37  of the suppression chamber  18  formed as part of the junction box, projects therefrom in a position to project into and through the window  22 . This positions the projecting portion  37  of the suppression chamber  18  within the window  22 . Thus the projecting portions  37  can be made to project through and forward of the window  22  in the cover and into surrounding open room spaces where electrified content items may connect to junction box. 
     In  FIGS. 30-30A  are depicted front and rear views of an especially preferred mode of a junction box  12  of the system herein. The junction box  12  is shown with transparent sidewalls  15 . As can be seen, the sidewalls  15  defining the cavity  13  of the junction box  12  have connected passages  21  within some or all of the sidewalls  15  which define the cavity  13  of the junction box  12 . Connections  29  for provision of fire retardant communicate with the passages  21  on one sidewall to communicate the fire retardant into the passage  21  of at least one sidewall, and preferably with passages  21  in other sidewalls  15  surrounding the cavity  13  such that fire retardant will flow into and through all of the passages  21  where positioned in sidewalls  15  of a junction box  12 . 
     This mode of the system herein configures portions of the junction box  12  itself to form the suppression chamber  18  in a unitary structure. In operation, should the electric connection within a cavity  13  of a junction box  12  overheat, at least one of the surfaces of the sidewall  15  defining the suppressant chamber within the junction box  12  and facing the cavity  13 , will melt and cause a communication of fire retardant from a passage  21  in that sidewall  15  into the cavity  13 . Alternatively, portions of common walls between the sidewall  15  and the cavity  13  may be fully or partially formed of material adapted to melt at the temperature slightly higher or lower than that of the insulation on the wires and melt when temperature inside the cavity  13  exceeds the melting temperature of the  26  conduit. 
     Further shown in  FIG. 30  is a projecting portion  37  of the suppression chamber formed by the junction box  12  itself. This projecting portion  37  in  FIG. 30  is sized to project into or through the windows  22  in the cover plate which is shown covered by a hood  43 . Should the projecting portion encounter a temperature high enough to melt, fire retardant from the suppression chamber, formed within the junction box  12  walls and communicating to the projecting portion  37 , will be directed downward by the hood  43 . 
     In  FIG. 31  is shown a junction box  12  of the system herein similar in operation to that of  FIG. 30 , where internal passages  21  at least one and preferably a plurality of the sidewalls  15  surrounding the interior cavity  13  of the junction box  12 , are in operative communication with the axial passage  25  of the operatively engaged fluid conduit  26 . In this fashion, fire retardant from the axial passage  25  communicates under pressure into one or more connected passages  25  formed within the sidewalls  15  surrounding the interior cavity  13  forming the suppression chamber  18  within the walls of the junction box  12  which surround the interior cavity  13  and any electric connection therein. As in  FIG. 30  the suppressant chamber  18 , is thus at least partly within the walls of the junction box  12  itself which are adapted to melt at the noted temperature levels herein. 
     Additionally shown in  FIG. 31  are the series of pointed projections  49  formed into the surfaces of the sidewall  15 . Should resistive heat or fire develop within or adjacent the junction box  12  sufficient to melt the sidewall  15 , the pointed projections  49  will cause a directional flow of fire suppressant gas or fluid therethrough as they individually melt. These projections  49  can be positioned within the interior cavity  13  and/or on the exterior surfaces of the junction box  12  whereby fire retardant can be projected to areas adjacent the junction box  12 . These triangular projections  49  allow for the charged suppression space to be closer to connection points or energized components as so desired. 
     In  FIG. 32  is depicted a junction box  12  of the system herein wherein the internal cavity  13  of the junction box  12  is accessible through a first side opening  44  by removal of a conventional cover plate  46 . Covering the second side opening  50  opposite the first side opening  44  is a suppression chamber  18  adapted to engage with the second side opening  50  and enclose the electric connections within a closed internal cavity  13 . 
     As depicted, a side surface  52  facing the internal cavity  13 , has fluid connections  29  adapted to engage the fluid conduits  26  in the circuit to communicate fire retardant through the chamber  18 . Also shown, formed into the side surface  52 , are recesses  54  adapted to hold electrical connections between two wires  28  such as wire nuts  56  secured over time. Further depicted are metal conduits  51  showing that the system herein can route the cable surrounded by the sheath  24  through metal conduits  51  in a commercial setting requiring such. Additionally depicted is a polymeric diaphragm  53  which fills an aperture in the cover plate  46 . This diaphragm  53  may be formed of a polymeric or other material adapted to melt at the appropriate temperature noted herein, to allow disbursement of fire retardant through the opening. The diaphragm also can be configured to have a burst pressure less that the enclosure to protect the enclosure structural integrity should over pressurization of the circuit occur thereby preventing the enclosure from structural failure from suppressant over-pressurization release. 
     In  FIG. 33 , is depicted a junction box  12  in a conventional fashion having sidewalls  15  which surround the internal cavity  13  and where punch-out portions of the sidewalls  15  are shown providing one or a plurality of openings for passage of wires into and out of the internal cavity  13 . Additionally depicted is an insertable track  41  routing winds of a fluid tube  58  which may be a continuation of, or be engaged at both ends to, the fluid conduit  26  to communicate fire retardant into and through the length of the fluid tube  58 . The fluid tube  58  may be pre-positioned or slid into a removable engagement with the junction box  12  and internal cavity through, an elongated slot  60  in one sidewall. Of course the track  41  may also engage a portion of the fluid conduit  26  from the cable  11  which would be engaged thereon in the circuitous route. The assembled mode of the junction box  12  of  FIG. 33  is shown in  FIG. 34  wherein the track  41  has been operatively engaged within the slot  60 . 
     Shown in  FIG. 34A  is a junction box  12  configured with one or a plurality of openings for passage of wires into the cavity  13  and through the junction box  12  similar to  FIG. 33 . Also shown is the slot  60  configured for insertion of the track  41  to hold a fluid tube in a circuitous path thereby forming the suppression chamber from windings of the fluid conduit  26  in a similar fashion to that of  FIG. 33 . Such might work well in retrofitting an older electrical system. 
     The engagement of the track  41  within the slot  60  is shown in  FIG. 34B . As depicted, the suppression chamber is formed by a winding of fluid conduit  26  on the track  41  which has been inserted operatively into the slot  60 . 
     Shown in  FIGS. 35 and 36  depict a mode of the system herein which is a closed system. As shown, the cable herein defines an extension cord  62  adapted for connection to a first or wall socket  16  which is operatively engaged in the cavity  13  of a remotely positionable housing or junction box  12 . This mode of the system herein is self contained and has a fluid conduit  26  communicating therethrough between a second socket  16  shown as plug receptacle  64  and an internally housed reservoir  66  of pressurized fire retardant within the housing. In this mode of the system, should the extension cord  62  overheat, the resulting communication of fire retardant to the overheating point on the extension cord  62  will extinguish any flame. While not shown, the apertures  32  can be formed in the flexible sheath of the cable forming the extension cord  62 . 
     A similar self contained mode of the system herein is shown in  FIG. 37 . As depicted a housing  68  is configured for positioning of larger electric components within the interior cavities  13  of the formed housing  68  which is defined by the surrounding sidewalls  15 . Shown in a transparent rendition the sidewalls  15  form an internal cavity having a reservoir  66  of fire retardant therein. The reservoir  66  connects through the fluid conduit  26  to the extension cord  62  to a remote plug receptacle  64 . This mode of the system would work well where the larger electronic component is for example used in a recreational vehicle or boat or other portable configuration, to guard against fire from resistive heating or sparking in wiring or overheating of the electronic component located proximate to the portable housing  68 . 
     Shown in  FIG. 38 ,  FIG. 38  depicts a junction box  12  which is operatively connected to a fluid conduit  26  which supplies suppressant fluid to passages  21 , such as in  FIG. 30A , to the junction box  12 . Shown, formed into the sidewall  15  of the junction box  12 , are differing configurations of nozzles  70 . These nozzles  70  are positioned on one or a plurality of the sidewalls  15  of the junction box  12  and can be configured for a targeted stream of suppressant in a directional flow  78  ( FIG. 39 ) therefrom. 
     As shown, one projecting nozzle  70 A has a narrowing configuration wherein the distal end  72  thereof, forms to a point which is narrower than a base  74  of the projecting nozzle  70 A. The nozzle sidewall or sidewalls  84  thus angle from the base  74  toward the distal end  72 . The distal end  72  can be formed to melt or burst when heated and supplied with pressurized fluid, and to disburse suppressant fluid therefrom in a narrow spread thereof or a singular stream thereof. Where used herein, nozzle sidewall  84  is intended to mean a single nozzle sidewall  84  which, for example, may have a tube-like or a conical shape, or may have intersecting angled portions forming the sidewall  84  which define the shape and size of the nozzle  70 . 
     A fluid opening  76 , as shown in  FIG. 39 , would thus be formed at the distal end  72  of the projecting nozzle  70 A, by a melting of a plug positioned in the fluid opening  76 , or a melting of the distal end  72  of the projecting nozzle  70 A. Fluid would disburse during a fire, or overheating of the area surrounding the junction box  12 , and the directional flow  78  of suppressant fluid as in  FIG. 39 , would flow therefrom. 
     By directional flow  78 , as used herein, is meant a fluid flow focused by the configuration of the nozzle  70  to be emitted as a straight line, a fanned spread either in a single plane or radial pattern emission, or any other pattern of fluid emission which can be formed by nozzle  70  sidewalls  84 . Further, while nozzles  70  are shown as projecting nozzles  70 A, and recessed nozzles  70 B, or dome shaped nozzles  70 C, herein, such is for convenience and any nozzle  70  which can be positioned on or in a sidewall  15  of a junction box  12 , to emit a focused or shaped fluid stream therefrom, is considered within the scope of this invention. 
     Also depicted in  FIG. 38  nozzles  70  formed as recessed nozzles  70 B which have a nozzle opening  80  which is wider than a nozzle inlet  82  which recessed into the sidewall  15 . In this mode, the inlet  82  end of the recessed nozzle  70 B is formed to melt or burst first when heated and allow fluid suppressant to flow from the inlet  82  end, to the wider nozzle opening  80 . The fluid direction is focused to emit in a fanned or radial pattern or highly disbursed fluid by angled nozzle sidewalls  84 . Changing the number and angle of the angled sidewalls  84  allows for a changing of the pattern of fluid in the directional flow  78  of suppressant. 
     Additionally shown in  FIG. 38  are dome shaped or domed nozzles  70 C. The domed nozzles  70 C can be formed as depressions into the sidewall  15  or a projecting domes from the sidewall  15 . The dome wall  86  defining the domed nozzles  70 C can be formed of a material which melts before the material forming the junction box  12  and sidewall  15  of the same material in a thinner layer such that it will melt before the junction box  12  and sidewall  13 . This mode of nozzle  70  can be employed to project a high volume of suppressant from the junction box  12  depending on the diameter or area forming the dome wall  86  of the domed nozzles  70 C. 
     As noted, shown in  FIG. 39  are exemplars of some of the nozzles  70  which can be formed to emit a narrow, pointed, or wide flood of suppressant fluid therefrom in the desired directional flow  78 . As also noted, the depictions in  FIG. 38-40  of the nozzles  70  should be in now way considered limiting. 
     As shown in  FIG. 40 , the nozzles  70  in all modes thereof, can be formed in nozzle panels  88 . While depicted with projecting nozzles  70 A, the nozzle panel  88  can be formed with any of the nozzle configurations herein, or which are shaped to emit the desired shape and volume of fluid in the directional flow  78  of choice. While shown as a single nozzle panel  88 , kits including a plurality of such nozzle panels  88  can be included in the system herein, wherein the user can choose the nozzle panel  88  having the desired configuration of nozzle  70  to emit a desired directional flow  78  of suppressant fluid therefrom in the desired pattern and volume determined by the shape or configuration of the nozzle  70 . 
     As shown in  FIG. 40 , the chosen nozzle panel  88  from the kit or plurality thereof, which has the desired nozzles  70  thereon, can be placed in a sealed engagement with the sidewall  15  of the junction box  12  which will have sidewall openings  90  in fluid communication with the suppressant communicated to the junction box  12  by the fluid conduit  26 . 
     A panel seal  92  forms a sealed engagement of the junction box  12  sidewall  15  with the nozzle panel  88  chosen for such engagement. A panel connector is employed to hold the nozzle panel  88  in a sealed connection to the junction box  12 . Such may be any panel connector configured to hold the nozzle panel  88  in the sealed connection to the sidewall  15  of the junction box  12 , such as slots  94  into which opposing sides of the nozzle panel  88  engage. The depicted slots  94  should be considered in no way limiting as to the panel connector employed to hold a nozzle panel  88  chosen to the sealed engagement with the junction box  12 . Any panel connector, such as snaps, pins, adhesive, or mating connectors positioned on the junction box  12  and on the nozzle panel  88 , or other mating connectors as would occur to those skilled in the art, may be used. 
     As noted, any of the different configurations and components can be employed with any other configuration or component shown and described herein.
