Patent ID: 8102226

Claim:
A protective electrical wiring device comprising: a housing assembly including a plurality of receptacle terminals comprising hot user-accessible terminal structure and a neutral user-accessible terminal structure accessible via at least one user-accessible receptacle, the hot user-accessible terminal structure and the neutral user-accessible terminal structure configured to receive plug contact blades inserted into the at least one user-accessible receptacle, the housing assembly further including a plurality of line terminals and a plurality of load terminals; a fault detection circuit coupled to the plurality of line terminals, the fault detection circuit being configured to detect at least one fault condition and provide a fault detect signal in response thereto, the at least one fault condition including a simulated fault condition; a circuit interrupting assembly coupled to the fault detection circuit, the circuit interrupting assembly being configured to establish electrical continuity between the plurality of line terminals, the plurality of load terminals and the plurality of receptacle terminals in a reset state and interrupt the electrical continuity in a tripped state, the circuit interrupting assembly including at least one first circuit interrupter member and at least one second circuit interrupter member, the at least one first circuit interrupter member being configured to drive the at least one second circuit interrupter member into the reset state in response to a make force, the at least one first circuit interrupter member and the at least one second circuit interrupter member being counter-driven into the tripped state by a break force; and at least one stop member disposed in a substantially fixed position relative to the housing assembly, the at least one stop member being configured to limit the movement of the at least one second circuit interrupter member such that a gap between the at least one first circuit interrupter member and the at least one second circuit interrupter member is substantially equal to a predetermined distance in the tripped state.
