Patent ID: 7713084

Claim:
A protective wiring device comprising: a housing including a front cover member having a user-accessible front major surface and a back cover member having a back major surface arranged substantially in parallel with the front major surface, the user-accessible front major surface including at least one set of plug blade apertures configured to accept a set of plug blades from a corded plug, the back cover member including a power input receptacle formed at a first housing end, the power input receptacle being configured to receive a power input plug configured to be coupled to a source of AC power; a set of receptacle terminals disposed within the front cover member, the set of receptacle terminals including a set of receptacle contacts that are accessible via the at least one set of plug blade apertures; a power input assembly including a set of power input contacts disposed in the back cover member within the power input receptacle, the set of power input contacts being configured to mate with the power input plug when the power input plug is inserted into the power input receptacle, the set of power input contacts being connected to a plurality of conductive paths, the plurality of conductive paths being coupled to the set of receptacle terminals in a reset state and decoupled from the set of receptacle terminals in a tripped state; and a protective electrical circuit assembly including a toroidal sensor assembly coupled to the power input assembly, the protective electrical assembly further including a printed circuit board disposed adjacent the set of power input contacts in a plane substantially parallel to the back major surface, the printed circuit board including a fault detection circuit, a solenoid assembly, and at least a portion of a circuit interrupter mounted thereon, the set of power input contacts, the solenoid assembly and the toroidal sensor assembly being arranged within a plane disposed between the printed circuit board and the set of receptacle terminals.
