Ground fault receptacle

Claim 1

In a duplex electrical receptacle providing ground fault protection and formed for mounting in a wall outlet box and for connecting an electrical load to the conductors of a power source, the improvement comprising: a container of electrical insulating material having an apertured shoulder portion extending to a forward face portion, said forward face portion having a pair of recessed portions formed to receive a test button and a re-set button respectively and a pair of duplex receptacles each formed to receive a ground connection prong and the prongs of a male plug; a metal support plate formed to telescope over said forward face portion and contact said shoulder portion of said container, said metal support plate having means for attachment thereof to a wall outlet box and a plurality of outstanding tab members formed to extend through said apertured shoulder portion and affix said metal support plate to said container; a pair of bus-bar conductors disposed within said container, each of said conductors having an electrical contact member affixed thereto and a male prong receiving portion aligned with each of said duplex receptacles; first and second resilient connectors each attached to an electrical conductor of said power source and having an electrical contact member aligned with the electrical contact member of one of said pair of bus-bar conductors; a re-set guide assembly disposed within said container and affixed to a re-set button disposed within one of said recessed portions of said face portion, said re-set guide assembly including ground fault circuit interrupting apparatus for effecting and interrupting contact between said electrical contact members of said bus-bar conductors and said first and second resilient connectors; a test button assembly including a test button disposed within one of said recessed portions of said face portion and a test button extension within said container and responsive to said test button for simulating a ground fault condition; a panel member of electrical insulating material disposed within said container and substantially covering said bus-bar conductors and resilient connectors and telescoped over said re-set guide and test button assemblies; a printed circuit board disposed within said container adjacent said panel member and including ground fault circuitry having a differential transformer telescoped over said electrical conductors of said power source, a solenoid adjacent said re-set guide assembly, and at least a pair of flexible plug-in spring members formed provide electrical connection of said power source conductors to said printed circuit board; and a back cover member of electrical insulating material affixed to said container substantially covering said printed circuit board.
