Patent ID: 8446234

Claim:
A protective electrical wiring device comprising: a housing assembly including a plurality of line terminals, a plurality of feed-through load terminals, and a plurality of receptacle load terminals; a circuit assembly including a fault detection circuit coupled to the plurality of line terminals, the fault detection circuit being configured to detect perturbations corresponding to a fault condition or a simulated fault condition, the fault detection circuit being configured to provide a fault detection signal in response to detecting the perturbations corresponding to the fault condition or the simulated fault condition; an interrupting contact assembly coupled to the fault detection circuit, the interrupting contact assembly including a contact assembly configured to provide electrical continuity between the plurality of line terminals, the plurality of feed-through load terminals, and the plurality of receptacle load terminals in a reset state, and interrupt the electrical continuity in a tripped state in response to the fault detection signal such that the plurality of line terminals, the plurality of feed-through load terminals, and the plurality of receptacle load terminals are isolated from each other, the contact assembly including a hot contact mechanism and a neutral contact mechanism configured to move in unison between the reset state and the tripped state, the hot contact mechanism comprising a hot contact member including a first hot contact disposed at an end portion of a first hot arm, a second hot contact disposed at an end portion of a second hot arm, and a third hot contact disposed at an end portion of a third hot arm, the neutral contact mechanism comprising a neutral contact member including a first neutral contact disposed at an end portion of a first neutral arm, a second neutral contact disposed at an end portion of a second neutral arm, and a third neutral contact disposed at an end portion of a third neutral arm.
