Patent ID: 8243402

Claim:
An electrical wiring system configured to be connected to a plurality of AC electric power conducting wires disposed between an AC power distribution point and a device box, the plurality of AC electric power conducting wires being accessible from an open front face of the device box after a rough-in installation phase, the system comprising: a plug connector assembly including a connector housing having a predetermined form factor, the plug connector housing including a plurality of plug connector contacts connected to a plurality of termination wire segments, each termination wire segment of the plurality of termination wire segments including a first wire segment portion coupled to a corresponding plug contact of the plurality of plug contacts and a second unterminated wire segment portion extending from the connector housing, each second unterminated wire segment portion of the plurality of termination wire segments being configured to be terminated to a corresponding one of the plurality of AC electric power transmitting wires after the rough-in installation phase; and an electrical wiring device comprising, a device housing including a cover member and at least one back body member, the cover member including a front major surface having at least one set of receptacle openings disposed therein, the at least one back body member including a rear major surface having an opening disposed in a portion thereof to form a power input receptacle configured to accommodate the plug connector housing, the at least one back body member also including a seating portion such that a planar region is substantially disposed between the seating portion and the rear major surface, the planar region being substantially parallel to the rear major surface, the at least one back body member further including at least one AC circuit compartment substantially disposed in planar region, a ground strap assembly including a mounting portion configured for attachment of the electrical wiring device to the device box, the seating portion accommodating at least a portion of the mounting portion, the ground strap assembly further comprising at least one output ground contact and an input ground contact, and an AC circuit assembly being substantially disposed in the at least one AC circuit compartment and configured to detect at least one fault condition, the AC circuit assembly being coupled to a plurality of input contacts including the input ground contact being disposed in the power input receptacle and a plurality of output contacts including the at least one output ground contact being accessible via the at least one set of receptacle openings, the plurality of power input contacts being configured to mate with the plurality of plug connector contacts when the connector housing is inserted into the power input receptacle such that electrical continuity is established between the AC power distribution point and the plurality of output contacts in a first state, the electrical continuity being interrupted in a second state.
