CROSS-REFERENCE TO RELATED APPLICATIONS 
     This application claims priority to U.S. Provisional Application No. 61/516,768 filed 7 Apr. 2011 and U.S. Provisional Application No. 61/630,677 filed 16 Dec. 2011, and U.S. Utility application Ser. No. 13/506,136 filed 29 Mar. 2012. 
    
    
     FIELD OF THE INVENTION 
     The present invention relates to an apparatus for locating electrical devices including pre-wired electrically isolated power sources deep within a walls interior. 
     BACKGROUND OF THE INVENTION 
     Some electrical appliances, particularly flat screen televisions, are mounted directly to the wall, so that externally connected plugs protruding out of the wall plate interfere with mounting the television in flat abutment with the surface of the wall. 
     There exists a need for an apparatus for positioning in-wall power such as electrically isolated receptacles, that are pre-wired, deep within a walls interior. An electrical box that can facilitate the mounting of such receptacles exterior to the box creates more space internal to the wall for isolating plugs and connectors. An electrical box that facilitates the mounting of other components such as speakers etc, and that includes a one piece enclosure that is adaptable for the placement of grills, etc, for a modern flush mounted look is also desirable. 
     SUMMARY OF THE INVENTION 
     The foregoing and other problems are overcome, and other advantages are realized, in accordance with the disclosed, alternative embodiments of these teachings. 
     The recessed box of the present invention is utilized to install electrical components behind a wall, such that the components are recessed within the wall. In one embodiment pre-wired electrically isolated female and male receptacles combined with the recessed box enclosures allow for the input and output receptacles to be mounted deep inside a wall for visual isolation of receptacle outlets and associated plugs/connectors that may also be present in the enclosure. Since the receptacles are encased and pre-wired, they are not required to be mounted internal to an electrical box for electrical isolation. This allows for the receptacles to be mounted externally to the electrical box enclosure, creating additional space within the box necessary for hiding connectors and the like. 
     Other electrical components and/or audio components may be mounted to the recessed box, and the recessed box can be mounted with a grille in place for applications were it is not desirable to visually see inside the recessed box.

     DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS 
     While certain embodiments of the present invention have been illustrated and described herein, the present invention should not be limited to such illustrations and descriptions. It should be apparent to those skilled in the art that changes and modifications may be incorporated and embodied as part of the present invention and are within the scope of the claims. 
       FIGS. 1-7  illustrate various embodiments of recessed electrical boxes or “deep Boxes”, that can be utilized with the present invention. Referring to  FIGS. 1-3 , the single gang recessed electrical box  120  includes an integrated face plate  122  with a flange  122 B that extends outward beyond the periphery of box  120  exterior surface  120 A. The box  120  includes wall mounting claws  124  that are adjustable to engage drywall or the like via positioning screws  122 A. The box includes connection apertures  120 B for securing any of the various embodiments of encased receptacles discussed herein. Opening  120 C is approximately dimensioned to the dimensions of the receptacle front surface  130  after mounting over opening  120 C, and is smaller than opening  120 D. As illustrated in  FIG. 1 , recessed box  120  includes an interior surface that projects rearward of opening  120 D up to a rear panel  120 E. Rear panel  120 E extends inward from sides  120 F of the interior surface and defines opening  120 C. Flange  122 B inner periphery  122 B 1  defines opening  120 D. A grille cover seating surface  1220  extends inward from the inner periphery  122 B 1  peripheral edge. An orthogonal surface stop  122 D provides an abutment to position an optional grille cover  130  within opening  120 D. 
     As illustrated in  FIG. 12 , a grille cover  130  may be placed within opening  120 D with grille cover  130 , frame  130 A 1 , side surfaces  130 A slideably engaging seating surfaces  122 C up to a point where grille cover  130  is secured against surfaces  122 D. 
     Since the electrical receptacles are electrically isolated and pre-wired in one of the various forms described herein, they can be mounted external to recessed electrical box  120 , as illustrated in  FIGS. 8-11 . This creates a deep opening within the wall, as illustrated in  FIG. 11 . 
     Encased receptacles that can be utilized with the recessed electrical boxes of the present invention may include both power input and power output, and coupling  15  which are electrically insulated and pre-wired to meet applicable building codes. 
     The encased receptacles  10  and  20  further include mounting frames  25 . The frames may be overmolded, or externally affixed to receptacles  10  and  20 . The Mounting frames  25  include tab connection holes  25 A. In the preferred embodiment, the mounting frames  25  are substantially co-planer with the front face of receptacles  10  and  20 . 
     As illustrated in  FIG. 10 , a larger front opening  120 D is of sufficient length and width to allow access to the mounted receptacles  10  located inward of opening  120 D. As illustrated in  FIG. 11 , in the field, a hole would be cut in the wall at a dimension less than the periphery of face plate  122 , flange  122 B. Utilizing the engagement claws  124  against the interior wall mounting surface  45 B by turning the positioning screws  122 A, the claws would force the Flange  122 B against the wall surface  45 B and bringing flange  122 B in contact with exterior wall surface  45 A for a secure fit. 
       FIGS. 4-5  illustrates a double gang “deep box” having the same functionality for the respective elements as described above, and further illustrates multiple openings  120 C, in rear panel  120 E.  FIGS. 6-7  illustrate an alternative embodiment of the double gang recessed electrical box having the same functionality for the respective elements as described above. It is understood that the exterior surfaces  120 A that defines the rearward projection of the recessed boxes may be sloped at various angles for particular installation requirements without departing from the scope of the present invention.
