Abstract:
1. An electrical wiring device comprising: a housing assembly including a plurality of line terminals, a plurality of load terminals, and a plurality of receptacle load terminals; a circuit assembly including at least one signal detection circuit, the at least one signal detection circuit being configured to detect at least one signal having predetermined signal characteristics propagating on the plurality of line terminals or the plurality of load terminals, the circuit assembly being configured to generate a detection stimulus in response to the at least one signal detection circuit detecting the at least one signal; an interrupting contact assembly coupled to the circuit assembly, the plurality of line terminals, the plurality of load terminals and the plurality of receptacle load terminals, the interrupting contact assembly including four sets of interrupting contacts being at least partially disposed on four cantilevered members, the four cantilevered members including a first set of two cantilevered members and a second set of two cantilevered members, the first set of cantilevered members being configured to rotate around a first axis in a first direction and the second set of cantilevered members being configured to rotate around a second axis in a second direction opposite to the first direction, the four sets of interrupting contacts being configured to provide electrical continuity between the plurality of line terminals, the plurality of load terminals, and the plurality of receptacle load terminals in a reset state, the four sets of interrupting contacts being decoupled in a tripped state to interrupt the electrical continuity between the plurality of line terminals, the plurality of load terminals and the plurality of receptacle load terminals.
