The enclosed switching apparatus of claim 2 wherein said enclosure further comprises a door hingeably attached to one of said top wall, said bottom wall, said first side wall, and said second side wall; and, wherein said door, when in a closed position, covers said first and second compartments. 6. The enclosed switching apparatus of claim 5 wherein said enclosure further comprises a locking mechanism associated with said door; and a safety latch for engaging said locking mechanism when said door is in said closed position and a primary power disconnect switch is in a closed "ON" position. 7. The enclosed switching apparatus of claim 5 wherein said enclosure further includes a ventilation device disposed on at least one of said top wall, said bottom wall, said first side wall, said second side wall, said back wall, and said door. 8. The enclosed switching apparatus of claim 1 wherein said receptacle is accessible from outside of said enclosure. 9. The enclosed switching apparatus of claim 8 wherein said enclosure further comprises a receptacle cover mounted on the outside of said enclosure, said receptacle cover operable to provide ingress protection for said receptacle. 10. An enclosed switching apparatus, comprising: an enclosure; a primary power supply disconnect mounted in said enclosure, said primary power supply disconnect having first and second terminals, said first terminals being electrically connectable to a primary power source and said second terminals being electrically connectable to a load; an auxiliary power supply unit comprising: an auxiliary power supply disconnect having third and fourth terminals, said third terminals being electrically connectable to said primary power source; a transformer having fifth and sixth terminals, said fifth terminals being electrically connected to said fourth terminals of said auxiliary power supply disconnect; an auxiliary fusible element having seventh and eighth terminals, said seventh terminal being electrically connected to one of said sixth terminals of said transformer; and a receptacle having ninth terminals thereon, one of said ninth terminals being electrically connected to said eighth terminal of said auxiliary fusible element; and a remotely mounted receptacle electrically connected to at least one of said terminals of said receptacle and said eighth terminal of said auxiliary fusible element. 11. The enclosed switching apparatus of claim 1 wherein said auxiliary power supply disconnect is one of a ground fault circuit breaker, a manual disconnect, a circuit breaker, a fused disconnect, an unfused disconnect, and a molded case "switch" type disconnect. 12. A safety switch comprising: a primary power supply unit electrically connectable between a first power supply line carrying a first voltage and a load operating at said first voltage; a receptacle; an auxiliary power supply unit electrically connectable between said first power supply line carrying said first voltage and said receptacle, said auxiliary power supply providing a second voltage to said receptacle; and an enclosure comprising a first compartment containing said primary power supply unit and a second compartment containing said auxiliary power supply unit. 13. The safety switch of claim 12 wherein said enclosure further comprises: a top wall, a bottom wall, a first side wall, and a second side wall, wherein a first end of said top wall is connected to a first end of said first side wall, a second end of said first side wall is connected to a first end of said bottom wall, a second end of said bottom wall is connected to a first end of said second side wall, and a second end of said second side wall is connected to a second end of said top wall, and wherein each of said top wall, said bottom wall, said first side wall, and said second side wall extend from a back wall; and an interior wall extending from said back wall, wherein said top wall, said bottom wall, said first side wall, said back wall, and said interior wall define said first compartment and wherein said top wall, said bottom wall, said second side wall, said back wall, and said interior wall define said second compartment. 14. The safety switch of claim 13 wherein said enclosure further comprises an inner panel mounted opposite to said back wall and covering at least a portion of said second compartment. 15.
