CROSS-REFERENCE TO RELATED APPLICATIONS 
     This application claims the benefit of U.S. Provisional Patent Application No. 63/272,887, filed Oct. 28, 2021. The disclosure of the priority application in its entirety is hereby incorporated by reference into the presence application. 
    
    
     TECHNICAL FIELD 
     The present disclosure relates generally to fuse seats that enable the fuse terminals of fuses in an enclosure to be properly inserted into fuse clips. 
     BACKGROUND 
     Fuses are used with a variety of electronic devices. A fuse is an electrical safety device that provides overcurrent protection to an electronic device. When a fault in the electronic device causes too much current to flow, a fuse breaks a circuit to interrupt the current flow. Typically, a fuse is held in a fuse housing that has fuse clips that secure and electrically connect to the terminals of the fuse. In some instances, at least one terminal of a fuse is partially inserted into a fuse clip, which can cause overheating at the terminal due to insufficient contact or insufficient contact pressure between the terminal and the fuse clip. Additionally, the fuse associated with the partially inserted terminal may not function as intended, which can result in the electronic device being damaged due to excessive current or heat. 
     SUMMARY 
     An enclosure that houses a fuse or fuses includes one or more fuse positioning structures. A fuse housing in the enclosure holds one or more fuses. Each fuse positioning structure includes one or more fuse seats. Each fuse seat is configured to contact and apply pressure to a respective fuse in the fuse housing. The fuse positioning structure(s) cause one or both terminals of each respective fuse to be seated properly in a respective fuse clip or fuse clips. The terminal(s) is seated properly when there is sufficient contact and/or sufficient contact pressure between the terminal and a respective fuse clip. 
     In one aspect, an enclosure includes an access door, a fuse housing, and one or more fuse positioning structures. The fuse housing is configured to hold at least one fuse. The fuse housing includes fuse clips for each fuse. The fuse clips are operable to receive the terminals of the fuse. The one or more fuse positioning structures are attached to an interior surface of the access door. The fuse positioning structure(s) include one or more fuse seats, where each fuse seat is operable to contact a respective fuse in the fuse housing. When the one or more fuses are inserted into the fuse housing and the access door is closed, each fuse seat contacts a respective fuse and causes the terminals of the fuse to be seated in the fuse clips. 
     In another aspect, an enclosure includes a fuse housing and one or more movable fuse positioning structures. The fuse housing is configured to hold at least one fuse, and the fuse housing includes fuse clips for each fuse. The one or more movable fuse positioning structures are operably attached to an interior surface of the enclosure or to the fuse housing. Each movable fuse positioning structure is operable to engage or disengage the one or more fuses. Each movable fuse positioning structure includes at least one fuse seat that is configured to contact a respective fuse. When the one or more fuses are inserted into the fuse housing and the one or more movable fuse positioning structures contact the fuse(s), the at least one fuse seat contacts a respective fuse to cause the terminals of the fuse to be seated in the fuse clips of the respective fuse. 
     In yet another aspect, an enclosure includes a fuse housing and one or more attachable fuse positioning structures. The fuse housing is configured to hold at least one fuse, and the fuse housing includes fuse clips for each fuse. The one or more attachable fuse positioning structures are operable to attach to an interior surface of the enclosure or to the fuse housing and detach from the interior surface of the enclosure or the fuse housing. Each attachable fuse positioning structure includes at least one fuse seat that is configured to contact a respective fuse. When the one or more fuses are inserted into the fuse housing and the one or more attachable fuse positioning structures positioned on either the interior surface of the enclosure or the fuse housing engages the one or more fuses, the at least one fuse seat contacts a respective fuse to cause the terminals of the fuse to be seated in the fuse clips for that fuse. 
     In some instances, the one or more fuses, via the fuse clips of the fuse housing, are electrically connected to a monitoring device. The monitoring device monitors one or more characteristics of the fuse(s). For example, the monitoring device can monitor a temperature level, a voltage level, voltage presence, and/or fuse continuity. The monitoring device is operably connected to one or more output devices that present a value of a monitored characteristic and/or an indication of the monitored characteristic.

     DETAILED DESCRIPTION 
     Embodiments disclosed herein provide fuse positioning structures that enable the proper insertion of fuse terminals into fuse clips. One or more fuses are included in an enclosure. The enclosure can be any suitable type of enclosure that houses one or more fuses. In a non-limiting nonexclusive example, the enclosure houses a fusible disconnect switch, where the disconnect switch combines a switch to connect and disconnect a circuit or an electrical device to and from a power supply, and one or more fuses that provide overcurrent protection. 
     In one embodiment, one or more fuse positioning structures that each include one or more fuse seats are attached to an interior side of an access door of an enclosure. The fuse seat(s) contact the fuse or fuses when the access door is closed to ensure each fuse is seated in a fuse slot and the fuse terminals of the fuse are inserted into and seated in the fuse clips. The fuse seat(s) push any partially seated fuse terminal into the fuse clips. 
     In another embodiment, one or more fuse positioning structures that each include one or more fuse seats are attached to a movable (e.g., pivotable, rotatable) structure or structures, or are implemented as movable (e.g., pivotable, rotatable) fuse positioning structures. Each movable structure(s) or movable fuse positioning structure(s) is operably attached to an interior surface of an enclosure, such as the rear interior surface, or to a fuse housing (e.g., a switch base). When an access door of an enclosure is open, a user can move each movable structure (or movable fuse positioning structure) to an open or first position where each fuse seat does not contact a respective fuse and enables access to the fuse(s). Similarly, when the access door is open, the user may move each movable structure (or movable fuse positioning structure) to a closed or second position to enable each fuse seat to contact a respective fuse for proper insertion of the fuse terminals into the fuse clip(s). 
     In yet another embodiment, one or more fuse positioning structures that each include one or more fuse seats are attached to a panel that is configured to be attached to, and detached from, an interior surface of an enclosure or a surface of a fuse housing (e.g., the switch base) when the access door is open. For example, the panel can be attached and detached using any suitable type of fastener or fasteners, such as a screw, a screw and wing nut, a push latch, a magnetic catch, a flex-grip and roller catch, or other type of latch or catch. When a panel is attached to the enclosure or to the fuse housing, each fuse seat contacts a respective fuse to ensure the proper insertion of the fuse terminals into the fuse clip(s). When the access door is open and the panel is detached from the surface, each fuse seat does not contact the respective fuse and enables access to the fuse(s). 
     In some embodiments, a fuse positioning structure can include one or more conductive structures that enable one or more characteristics of a fuse, or of the operation of the disconnect switch, to be monitored. Each conductive structure contacts a respective fuse clip to provide an electrical contact with the fuse. The conductive structure is also electrically connected to a sensing or monitoring device that monitors the one or more characteristics, such as a temperature level, a voltage level, voltage presence, and/or fuse continuity. The monitoring device is operably connected to one or more output devices that present a value of a monitored characteristic and/or an indication of the monitored characteristic. For example, the monitoring device may be operably connected to a display that displays a level of the monitored characteristic (e.g., a voltage level). In some embodiments, the monitoring device is operably connected to one or more light indicators (e.g., light emitting diodes) that illuminate or do not illuminate to represent a monitored characteristic. 
       FIG.  1    illustrates a block diagram of example electrical system  100  in accordance with the principles of the present disclosure. The electrical system  100  includes a power supply  102  operably connected to one or more fuses  104 . The power supply  102  can provide any suitable power, such as six hundred volts (600 V) alternating current (AC), two hundred and forty volts (240 V) AC or one hundred and twenty volts (120 V) AC. 
     The fuse(s)  104  are operably connected to an electrical device  106 . Non-limiting nonexclusive examples of a fuse  104  is a Class H or a Class R replaceable one-time use fuse. In one example, when the electrical device  106  is in use, the one or more fuses protect the electrical device  106  from currents that exceed the ampere rating of the electrical device  106  (e.g., over currents). 
       FIG.  2    illustrates an example enclosure  200  with an access door  210  in a closed position. The enclosure  200  can be made of any suitable material, such as metal. In the illustrated example, the enclosure  200  houses a disconnect switch (e.g., disconnect switch  301  in  FIG.  3   ) that includes one or more fuses. A switch arm  202  positioned on the exterior of the enclosure  200  is operably connected to the disconnect switch to close and open the disconnect switch. The switch arm  202  can be positioned in a first position to turn off the disconnect switch (e.g., to open the disconnect switch), or in a second position to turn on the disconnect switch (e.g., to close the disconnect switch). 
     The enclosure  200  includes mounting flanges  204  that each define openings  206  for mounting the enclosure  200  on a wall or some other structure. The mounting flanges  204  can be positioned on one or more sides of the enclosure  200 . In  FIG.  2   , the mounting flanges  204  are positioned on opposing top and bottom sides of the enclosure  200 . In some embodiments, the enclosure  200  includes one or more interlock switches  208  that can prevent the opening of the access door  210 . The disconnect switch and the one or more fuses are accessible when the access door  210  is opened. 
       FIG.  3    illustrates the enclosure  200  with the access door  210  in an open position. As discussed in conjunction with  FIG.  2   , the enclosure  200  houses a disconnect switch  301 . The interior of the enclosure  200  includes a fuse housing  300  that includes one or more fuse slots. In the example, the fuse housing  300  includes three fuse slots  302   a ,  302   b ,  302   c . A fuse  304  can be seated into each fuse slot  302   a ,  302   b ,  302   c.    
     The example fuse  304  includes a fuse body  306 , a first terminal  308 , and a second terminal  310 . The first terminal  308  is inserted into and held by a first fuse clip  312  in a respective fuse slot  302   a ,  302   b ,  302   c . The second terminal  310  is inserted into and held by a second fuse clip  314  in the respective fuse slot  302   a ,  302   b ,  302   c . The first fuse clips  312  are positioned at the top of the fuse slots  302   a ,  302   b ,  302   c  at an upper region of the fuse housing  300 . The second fuse clips  314  are positioned at the bottom of the fuse slots  302   a ,  302   b ,  302   c  at a lower region of the fuse housing  300 . In the illustrated example, the first and the second fuse clips  312 ,  314  are spring-loaded fuse clips, and the first and the second terminals  308 ,  310  are pushed into the first and the second fuse clips  312 ,  314 , respectively, when the fuse body  306  is inserted into the fuse slot  302   a ,  302   b ,  302   c . The first and the second fuse clips  312 ,  314  provide and maintain contact pressure on the first and the second terminals  308 ,  310  through the spring action. 
     The first and the second terminals  308 ,  310  electrically connect with the first and the second fuse clips  312 ,  314 , respectively, when the fuses  304  are seated in the fuse slots  302   a ,  302   b ,  302   c . The first and the second terminals  308 ,  310  can be inserted properly into the first and the second fuse clips  312 ,  314  prior to closing (e.g., turning on) the disconnect switch. However, in some instances, at least one terminal may be partially inserted into a fuse clip. The partial seating of a terminal can cause overheating at the terminal due to insufficient contact and/or insufficient contact pressure between the terminal and the fuse clip. Additionally or alternatively, the fuse associated with a partially inserted terminal may not function as intended. As will be described in more detail later, one or more fuse positioning structures can be included in an enclosure to seat the terminals properly into the fuse clips. 
       FIG.  4    illustrates a first example enclosure  400  that includes first and second fuse positioning structures  408 ,  410  in accordance with the principle of the present disclosure. The enclosure  400  includes the fuse housing  300  that is configured to hold fuses  402 ,  404 ,  406 . In the illustrated example, the three fuses  402 ,  404 ,  406  each include first and second terminals  308 ,  310  that can be inserted into respective fuse slots  302   a ,  302   b ,  302   c  (see  FIG.  3   ) in the fuse housing  300 . The first fuse positioning structure  408  and the second fuse positioning structure  410  are attached to an interior surface  412  of the access door  210 . The first and the second fuse positioning structures  408 ,  410  each include fuse seats  414 ,  416 ,  418 . The fuse seats  414 ,  416 ,  418  are configured to contact and apply pressure to the fuses  402 ,  404 ,  406  when the access door  210  is closed. 
     Although two fuse positioning structures  408 ,  410  are shown in  FIG.  4   , other examples are not limited to this configuration. An enclosure can include one or more fuse positioning structures, and each fuse positioning structure may have one or more fuse seats. Additionally, each fuse positioning structure may be attached to the interior surface  412  of the access door  210  at any suitable location. 
     In the illustrated example, the first fuse positioning structure  408  is attached to the interior surface  412  of the access door  210  at a first location  420  that corresponds to a second location  422  of each fuse  402 ,  404 ,  406 . The second fuse positioning structure  410  is attached to the interior surface  412  of the access door  210  at a third location  424  that corresponds to a fourth location  426  of the fuses  402 ,  404 ,  406 . In  FIG.  4   , the second location  422  of the fuses  402 ,  404 ,  406  is an upper region of each fuse  402 ,  404 ,  406  near or adjacent the first fuse clips  312 , and the fourth location  426  of the fuses  402 ,  404 ,  406  is a lower region of each fuse  402 ,  404 ,  406  near or adjacent the second fuse clips  314 . When the access door  210  is closed, the fuse seats  414 ,  416 ,  418  of the first fuse positioning structure  408  contact the fuses  402 ,  404 ,  406  at the second location  422  and cause the first terminals  308  of the fuses  402 ,  404 ,  406  to be seated in the first fuse clips  312 . Similarly, the fuse seats  414 ,  416 ,  418  of the second fuse positioning structure  410  contact the fuses  402 ,  404 ,  406  at the fourth location  426  and cause the second terminals  310  of the fuses  402 ,  404 ,  406  to be seated in the second fuse clips  314 . 
       FIG.  5    illustrates an enlarged view of the fuse housing shown in  FIG.  4   .  FIG.  5    shows the fuses  402 ,  404 ,  406  seated in the fuse slots  302   a ,  302   b ,  302   c  of the fuse housing  300  and the first and the second fuse positioning structures  408 ,  410  contacting the fuses  402 ,  404 ,  406 . Although the access door  210  is closed in  FIG.  7   , the access door  210  is not shown to enable the fuse housing  300 , the fuses  402 ,  404 ,  406 , and the first and the second fuse positioning structures  408 ,  410  to be visible. 
     The fuse seats  414 ,  416 ,  418  of the first fuse positioning structure  408  contact the fuses  402 ,  404 ,  406  at the second location  422  of the fuses  402 ,  404 ,  406 , and the fuse seats  414 ,  416 ,  418  of the second fuse positioning structure  410  contact the fuses  402 ,  404 ,  406  at the fourth location  426  of the fuses  402 ,  404 ,  406 . The fuse seats  414 ,  416 ,  418  of the first and the second fuse positioning structures  408 ,  410  provide and maintain contact pressure on the fuses  402 ,  404 ,  406 . The contact pressure applied by the fuse seats  414 ,  416 ,  418  of the first fuse positioning structure  408  causes the terminals (e.g., the first terminal  308 ) of the fuses  402 ,  404 ,  406  to be seated properly into respective first fuse clip  312 . Similarly, the contact pressure applied by the fuse seats  414 ,  416 ,  418  of the second fuse positioning structure  410  causes the terminals (e.g., the second terminal  310 ) of the fuses  402 ,  404 ,  406  to be seated properly into respective second fuse clip  314 . In one example, the size, the shape, and the dimensions of the first and the second fuse positioning structures  408 ,  410  can be based on the number of fuses, the distance between the access door and the fuse(s), the profile of the fuse(s), and/or the size of the fuse(s). Additionally or alternatively, the size and the shape of each fuse seat  414 ,  416 ,  418  can be based on the number of fuses, the size of the fuse that the fuse seat  414 ,  416 ,  418  will contact, the dimensions of the fuses, and the profile of the bodies of the fuses. 
       FIG.  6    illustrates a second example enclosure  400   a  that includes one fuse positioning structure in accordance with the principles of the present disclosure. A fuse positioning structure (e.g., first fuse positioning structure  408 ) is attached to the interior surface  412  of the access door  210  at a fifth location  600  that corresponds to a sixth location  602  of each fuse  402 ,  404 ,  406 . When the access door  210  is closed, the fuse seats  414 ,  416 ,  418  of the first fuse positioning structure  408  contact the fuses  402 ,  404 ,  406  at the sixth location  602  of the fuses  402 ,  404 ,  406  to seat the first and the second terminals  308 ,  310  of the fuses  402 ,  404 ,  406  into respective first and second fuse clips  312 ,  314 . 
     The sixth location  602  of the fuses  402 ,  404 ,  406  in the illustrated example is generally a middle region of each fuse  402 ,  404 ,  406 . In one example, the middle region is substantially at a midpoint between the first fuse clip  312  and the second fuse clip  314  in a fuse slot (e.g., fuse slot  302   a  in  FIG.  3   ). In another example, the middle region is substantially at a midpoint of the fuse body (e.g., a midpoint of a length L of the fuse body  306  in  FIG.  3   ). 
       FIG.  7    illustrates an enlarged view of the fuse housing shown in  FIG.  6   . Although the access door  210  is not shown, it is deemed closed to show the fuse housing  300 , the fuses  402 ,  404 ,  406 , and the first fuse positioning structure  408 . The fuses  402 ,  404 ,  406  are seated in respective fuse slots  302   a ,  302   b ,  302   c  of the fuse housing  300 , and the first fuse positioning structure  408  contacts the fuses  402 ,  404 ,  406  at the sixth location of the fuses  402 ,  404 ,  406 . When the access door  210  is closed, the contact pressure applied by the fuse seats  414 ,  416 ,  418  of the first fuse positioning structure  408  causes the terminals (e.g., the first and second terminal  308 ,  310 ) of the fuses  402 ,  404 ,  406  to be seated properly into respective first and second fuse clips  312 ,  314 . 
       FIG.  8    illustrates a perspective view of the first fuse positioning structure  408  with attachment structures in accordance with the principles of the present disclosure. The first fuse positioning structure  408  is similar to the second fuse positioning structure  410 . As such, only the first fuse positioning structure  408  will be described. 
     The example first fuse positioning structure  408  includes the fuse seats  414 ,  416 ,  418 . The number of fuse seats  414 ,  416 ,  418  for the first fuse positioning structure  408  is based on the number of fuses the fuse seats  414 ,  416 ,  418  will contact or on the number of fuses to be seated in a fuse housing. In the example of  FIGS.  3 - 7   , the fuse housing  300  is configured to hold three fuses (e.g., fuses  402 ,  404 ,  406 ). Accordingly, the first fuse positioning structure  408  has the three fuse seats  414 ,  416 ,  418 . 
     The size and the shape of each fuse seat  414 ,  416 ,  418  in the illustrated example are based on the size of the fuse that the fuse seat  414 ,  416 ,  418  will contact, the number of fuses, the dimensions of the fuses, and the profiles of the bodies of the fuses (e.g., fuse body  306 ). In the example shown in  FIGS.  4 - 7   , the fuses  402 ,  404 ,  406  have cylindrical fuse bodies, and the shape and the size of each fuse seat  414 ,  416 ,  418  is based on a profile (e.g., the curvature) of the section of the fuse that will contact the fuse seat  414 ,  416 ,  418 . A fuse body can have a different shape and/or size in other examples. For example, a fuse body may have a rectangular shape, although alternatives are possible. 
     The attachment structures  800 ,  802 ,  804  may be positioned adjacent respective fuse seats  414 ,  416 ,  418 . In the illustrated example, each attachment structure  800 ,  802 ,  804  includes openings  806 ,  808 . Each attachment structure  800 ,  802 ,  804  is used to attach, via the openings  806 ,  808 , conductive structures  900 ,  902 ,  904  (see  FIG.  9   ) to the first fuse positioning structure  408 . As will be described in more detail in conjunction with  FIG.  9   , the conductive structures  900 ,  902 ,  904  are configured to contact respective fuse clips  312 ,  314 . For example, the conductive structures  900 ,  902 ,  904  are configured to contact fuse clips  312 ,  314  adjacent the attachment structure  800 ,  802 ,  804  to form an electrical connection between the conductive structures  900 ,  902 ,  904  and the fuse clips  312 ,  314 . The electrical connection to the fuse clips creates an electrical connection between the respective conductive structures  900 ,  902 ,  904  and the first and second terminals  308 ,  310  inserted in the fuse clips  312 ,  314 . The conductive structures  900 ,  902 ,  904  are also electrically connected to a monitoring device, such as an example monitoring device  1404  shown in  FIG.  14   . Thus, the conductive structures can be used to create an electrical connection between the fuse (via the terminals in the fuse clips) and the monitoring device, which enables one or more characteristics of the fuse to be monitored. 
       FIG.  9    illustrates the first fuse positioning structure  408  with the conductive structures  900 ,  902  attached to the attachment structures  800 ,  802 , respectively, via fasteners  910 ,  912 . A conductive structure  904  is shown detached from the attachment structure  804 . As described above, the conductive structures  900 ,  902 ,  904  are operable to contact the first and second fuse clips  312 ,  314  when the first fuse positioning structure  408  contacts the fuses  402 ,  404 ,  406  (e.g., when the access door  210  ( FIG.  2   ) is closed). One or more dimensions of the conductive structures  900 ,  902 ,  904  (e.g., the height) is determined so the conductive structures  900 ,  902 ,  904  push or bend against the first and second fuse clips  312 ,  314 . The bending of the conductive structures  900 ,  902 ,  904  against the first and second fuse clips  312 ,  314  produces a desirable or proper contact between the first and second fuse clips  312 ,  314  and the conductive structures  900 ,  902 ,  904  when the first fuse positioning structure  408  is in contact with the fuses  402 ,  404 ,  406 . In the example shown in  FIGS.  4 - 7   , the conductive structures  900 ,  902 ,  904  push or bend against the first and second fuse clips  312 ,  314  when the access door  210  is closed. 
     The conductive structures  900 ,  902 ,  904  define openings  906 ,  908  for receiving the fasteners  910 ,  912  to provide an attachment mechanism. To attach a conductive structure  900 ,  902 ,  904  to a respective attachment structure  800 ,  802 ,  804 , the conductive structure  900 ,  902 ,  904  is positioned adjacent the respective attachment structure  800 ,  802 ,  804  such that the openings  906 ,  908  align with the openings  806 ,  808  of the attachment structures  800 ,  802 ,  804 . The fastener  910  is inserted through the aligned openings  806 ,  906 , and the fastener  912  is inserted through the aligned openings  808 ,  908  to attach each conductive structure  900 ,  902 ,  904  to the respective attachment structure  800 ,  802 ,  804 . In the illustrated embodiment, the openings  806 ,  808 ,  906 ,  908  are threaded openings and the fasteners  910 ,  912  are screws, although other embodiments are not limited to this type of attachment mechanism. 
     A conductive line can be operably connected to a respective conductive structure  900 ,  902 ,  904 . Only one conductive line  914  is shown in  FIG.  9   . In a non-limiting example, the conductive lines can be soldered to the conductive structures  900 ,  902 ,  904 . The conductive lines can also be operably connected to the monitoring device  1404  (see  FIG.  14   ) to electrically connect the conductive structures  900 ,  902 ,  904  to the monitoring device  1404 . Fuses in a fuse housing can be electrically and operably connected to the monitoring device  1404  via fuse clips and associated conductive structures. 
     Other examples are not limited to the construction of the conductive structures  900 ,  902 ,  904 , and/or to the attachment mechanism used to attach the conductive structures  900 ,  902 ,  904  to the fuse positioning structure  408 . Any suitably configured conductive structure can be used to electrically connect a fuse terminal, via a fuse clip, to a monitoring device. Additionally, conductive structures can be attached to a fuse positioning structure using any suitable attachment mechanism. For example, a conductive structure can be positioned to contact a fuse clip and may be attached to a fuse positioning structure with an adhesive. 
       FIG.  10    illustrates a third example enclosure  400   b  that includes a movable fuse positioning structure  1000  in accordance with the principles of the present disclosure, where the movable fuse positioning structure  1000  is not in contact with the fuses  402 ,  404 ,  406 . For simplicity, the access door  210  of the enclosure  400   b  is not shown in  FIG.  10   . 
     The enclosure  400   b  includes the fuse housing  300  with fuses  402 ,  404 ,  406  inserted into the fuse slots  302   a ,  302   b ,  302   c  of the fuse housing  300 , and the movable fuse positioning structure  1000 . In the illustrated example, a first end  1002  of the movable fuse positioning structure  1000  is attached to the fuse housing  300  by a hinged attachment structure  1004  (e.g., a pin member). The movable fuse positioning structure  1000  is similar to the first fuse positioning structure  408  shown in  FIG.  8    except for the cutout  1006  at a second end  1008  of the movable fuse positioning structure  1000 . 
     The hinged attachment structure  1004  enables the movable fuse positioning structure  1000  to rotate onto and away from the fuses  402 ,  404 ,  406 . In the illustrated embodiment, when the movable fuse positioning structure  1000  is rotated in a first direction  1010  to cause the movable fuse positioning structure  1000  to contact the fuses  402 ,  404 ,  406 , the fuse seats  414 ,  416 ,  418  of the movable fuse positioning structure  1000  contact the fuses  402 ,  404 ,  406  at the sixth location  602 . The fuse seats  414 ,  416 ,  418  apply pressure to the fuses  402 ,  404 ,  406  to seat the first and second terminals  308 ,  310  of the fuses  402 ,  404 ,  406  into respective first and second fuse clips  312 ,  314 . The fuse seats  414 ,  416 ,  418  do not contact the fuses  402 ,  404 ,  406  when the movable fuse positioning structure  1000  is rotated in a second direction  1012  away from the fuses  402 ,  404 ,  406 . 
     Although  FIG.  10    depicts one movable fuse positioning structure  1000 , other examples are not limited to this implementation. For example, an enclosure can include one or more movable fuse positioning structures that are each positioned at any suitable location with respect to the fuses  402 ,  404 ,  406 . For example, the enclosure  400   b  may include two movable fuse positioning structures  1000  that contact the fuses  402 ,  404 ,  406  at locations similar to the second and the fourth locations  422 ,  426  shown in  FIG.  4   . Additionally, the movable fuse positioning structure  1000  can be operably attached to a switch housing or to an interior surface of the enclosure using a different type of attachment structure. Any suitable attachment structure that is operable to move the movable fuse positioning structure(s) with respect to the fuses  402 ,  404 ,  406  can be used. For example, a movable fuse positioning structure may be movable with respect to the fuses  402 ,  404 ,  406  via a sliding attachment structure. 
       FIG.  11    illustrates the third example enclosure shown in  FIG.  10    with the movable fuse positioning structure  1000  in contact with the fuses  402 ,  404 ,  406  in accordance with the principles of the present disclosure. For simplicity, the access door  210  of the enclosure  400   b  is not shown in  FIG.  11   . 
     The fuses  402 ,  404 ,  406  are seated in respective fuse slots  302   a ,  302   b ,  302   c  of the fuse housing  300 , and the movable fuse positioning structure  1000  has been rotated in the first direction  1010  to contact the fuses  402 ,  404 ,  406  at the sixth location  602  of the fuses  402 ,  404 ,  406 . In the illustrated example, the movable fuse positioning structure  1000  is secured to the fuse housing  300  at the second end  1008  of the movable fuse positioning structure  1000  with a fastener  1100  (e.g., a wing nut). For example, a screw on the fuse housing  300  can extend through the cutout  1006  ( FIG.  10   ) and be used to secure the movable fuse positioning structure  1000  to the fuse housing  300  via the fastener  1100 . Other examples can use a different type of fastener, such as a screw that is inserted through the cutout  1006  and inserted into a threaded insert in the fuse housing  300 . 
     In other examples, the movable fuse positioning structure  1000  can be held against the fuses  402 ,  404 ,  406  using any suitable mechanism. For example, in another example, a movable fuse positioning structure can have a given height that is determined based on a distance between an interior surface of an access door of the enclosure  400   b  and the fuses  402 ,  404 ,  406 . When the access door is closed, the interior surface of the access door can press against the movable fuse positioning structure  1000  to cause the first and the second terminals  308 ,  310  of the fuses  402 ,  404 ,  406  to be seated into respective first and second fuse clips  312 ,  314 . Thus, the movable fuse positioning structure can be pressed against the fuses  402 ,  404 ,  406  without the use of a fastener. 
       FIG.  12    illustrates a fourth example enclosure  400   c  that includes an attachable fuse positioning structure  1200  in accordance with the principles of the present disclosure, where the attachable fuse positioning structure  1200  is not in contact with the fuses  402 ,  404 ,  406 . For simplicity, an access door of the enclosure  400   c  is not shown in  FIG.  12   . 
     The enclosure  400   c  also includes the fuse housing  300 , fuses  402 ,  404 ,  406  inserted into the fuse slots  302   a ,  302   b ,  302   c  of the fuse housing  300 . A first cutout  1202  is formed in a first end  1204  of the attachable fuse positioning structure  1200 , and a second cutout  1206  is formed in a second end  1208  of the attachable fuse positioning structure  1200 . The attachable fuse positioning structure  1200  is similar to the first fuse positioning structure  408  shown in  FIG.  8    except for the first and the second cutouts  1202 ,  1206 . 
     A first post  1210  is attached to the fuse housing  300  at a first location  1211  that corresponds to the first cutout  1202 . A second post  1212  is attached to the fuse housing  300  at a second location  1213  opposite the first location  1211  that corresponds to the second cutout  1206 . The first and the second posts  1210 ,  1212  are configured to extend through the first and the second cutouts  1202 ,  1206 , respectively, when the attachable fuse positioning structure  1200  contacts the fuses  402 ,  404 ,  406 . A first fastener  1214  is configured to attach to the first post  1210  and a second fastener  1216  is configured to attach to the second post  1212  to secure the attachable fuse positioning structure  1200  to the fuse housing  300 . When the attachable fuse positioning structure  1200  is secured to the fuse housing  300 , the fuse seats  414 ,  416 ,  418  contact and apply pressure to the fuses  402 ,  404 ,  406  to seat the first and the second terminals  308 ,  310  of the fuses  402 ,  404 ,  406  into respective first and second fuse clips  312 ,  314 . 
     When the attachable fuse positioning structure  1200  is to be detached from the fuse housing  300 , the first and the second fasteners  1214 ,  1216  are detached from the first and the second posts  1210 ,  1212 . Once the first and the second fasteners  1214 ,  1216  are detached, the attachable fuse positioning structure  1200  can be lifted off the fuses  402 ,  404 ,  406  to enable a user to access the fuses  402 ,  404 ,  406 . 
     In the illustrated example, the first and the second posts  1210 ,  1212  are threaded posts and the first and the second fasteners  1214 ,  1216  are wing nuts. In other example, the attachable fuse positioning structure  1200  can contact and be secured against the fuses  402 ,  404 ,  406  using any suitable attachment mechanism. For example, the first and the second fasteners  1214 ,  1216  may be screws that are inserted into the first and the second cutouts  1202 ,  1206 , respectively, and received by a threaded insert in the fuse housing  300 . 
     Although  FIG.  12    depicts one attachable fuse positioning structure  1200 , other examples are not limited to this implementation. The enclosure  400   c  can include one or more attachable fuse positioning structures that are each positioned at any suitable location with respect to the fuses  402 ,  404 ,  406 . For example, the enclosure  400   c  may include two attachable fuse positioning structures  1200  that contact the fuses  402 ,  404 ,  406  at locations similar to the second and the fourth locations  422 ,  426  shown in  FIG.  4   . Additionally, the attachable fuse positioning structure  1200  can be operably attached to an interior surface of the enclosure  400   c  in addition to, or instead of, a fuse housing. 
       FIG.  13    illustrates the fourth example enclosure  400   c  shown in  FIG.  12    with the attachable fuse positioning structure  1200  in contact with the fuses  402 ,  404 ,  406  in accordance with the principles of the present disclosure. For simplicity, the access door of the enclosure  400   c  is not shown in  FIG.  13   . 
     The fuses  402 ,  404 ,  406  are shown seated in respective fuse slots  302   a ,  302   b ,  302   c  of the fuse housing  300 , and the fuse seats  414 ,  416 ,  418  of the attachable fuse positioning structure  1200  contact the fuses  402 ,  404 ,  406  at the sixth location  602  of the fuses  402 ,  404 ,  406 . In the illustrated example, the attachable fuse positioning structure  1200  is secured to the fuse housing  300  via the attachment of the first and the second fasteners  1214 ,  1216  to the first and the second posts  1210 ,  1212 , respectively. 
     The movable fuse positioning structure  1000  shown in  FIG.  10    and/or the attachable fuse positioning structure  1200  depicted in  FIG.  12    can include one or more conductive structures that are used to electrically connect one or more fuse clips to a monitoring device. For example, the conductive structures can be similar to the conductive structures  900 ,  902 ,  904  shown in  FIG.  9   . 
       FIG.  14    illustrates a block diagram of the example monitoring device  1404  in accordance with the principles of the present disclosure. The conductive lines  1400 ,  1402  that are operably attached to conductive structures in the enclosure  400  provide data signals to the monitoring device  1404 . The conductive lines  1400 ,  1402  each represent one or more conductive lines. In one embodiment, the conductive line  1400  is the conductive line  914  shown in  FIG.  9    and the conductive line  1402  is a separate conductive line that is attached to the same conductive structure (e.g., conductive structure  902 ) or to another conductive structure (e.g., conductive structure  904  in  FIG.  9   ). In another embodiment, the conductive lines  1400 ,  1402  are different conductive lines that are operably connected to the conductive lines (e.g., conductive line  914 ) attached to the conductive structures in the enclosure  400  (e.g., conductive structures  902 ,  904 ,  906  in  FIG.  9   ). 
     The data signals received from the conductive structures in the enclosure  400  (e.g., conductive structures  900 ,  902 ,  904  in  FIG.  9   ) can be input into a voltage monitoring device  1406  via the conductive line  1400 . In a non-limiting example, the voltage monitoring device  1406  is implemented as one or more voltage measurement circuits, a digital or analog multimeter, or a voltmeter. The voltage monitoring device  1406  can be used, for example, to detect the presence of a voltage at a fuse clip and/or to measure a voltage level at the fuse clip. 
     In some examples, the monitoring device  1404  includes a temperature monitoring device  1408  in addition to, or as an alternative to, the voltage monitoring device  1406 . The data signals received from the conductive structures in the enclosure  400  (e.g., conductive structures  900 ,  902 ,  904  in  FIG.  9   ) can be input into the temperatures monitoring device  1408  via the conductive line  1402 . The temperature monitoring device  1408  senses the temperature at a fuse clip. In a non-limiting example, the temperature monitoring device  1408  is implemented as one or more thermistors, one or more temperature sensors, or a digital or analog multimeter. 
     The example monitoring device  1404  can include one or more output devices (collectively referred to as output device  1410 ). Example output devices include, but are not limited to, a display, one or more light indicators (e.g., light emitting diodes), and/or one or more speakers. The output device  1410  is used to provide a value of a monitored characteristic and/or an indication of the monitored characteristic or characteristics (e.g., voltage level, voltage presence, and/or temperature level). The output device  1410  enables the monitored characteristic(s) to be determined and monitored by a person regardless of whether the access door of the enclosure (e.g., access door  210  in  FIG.  2   ) is opened or closed. 
     In some examples, the monitored characteristic(s) is monitored remotely. One or more communication devices (represented by communication device  1412 ) can be included in the monitoring device  1404 . The communication device  1412  may be a wired or a wireless communication device. Example communication devices include, but are not limited to, a near field probe, a short-range wireless device (e.g., BLUETOOTH), a mobile communication device (e.g., cellular), a Wi-Fi device, or combinations thereof. 
     A power supply  1414  is operably connected to the voltage monitoring device  1406  and/or the temperature monitoring device  1408 . The power supply  1414  may also be operably connected to the output device  1410  and the communication device  1412 . Any suitable power supply can be used, such as a battery (or batteries), a wired power adaptor that plugs into an electrical outlet (e.g., a wall outlet), or another electrical device that is operably connected to the monitoring device  1404  (e.g., a USB connector between the monitoring device and a computing device). 
     As discussed earlier, some or all of the components in the monitoring device  1404  can be included in an enclosure (e.g., enclosure  400 ) or positioned remotely from an enclosure. For example, the power supply  1414 , the voltage monitoring device  1406  and/or the temperature monitoring device  1408 , and the communication device  1412  are included in an enclosure while the output device  1410  is positioned remote from the enclosure. 
     Alternatively, the voltage monitoring device  1406 , the temperature monitoring device  1408 , the output device  1410 , the communication device  1412 , and the power supply  1414  may be positioned outside of the enclosure (e.g., on a remote panel). In such examples, the conductive lines  1400 ,  1402  can connect to one or more conductive contacts or voltage taps within the enclosure (e.g., where other signal lines or cables enter the enclosure) and separate conductive lines can connect the conductive contacts to the monitoring device  1404 .
