Abstract:
1. An electrical wiring device comprising: a plurality of line terminals configured to be connected to a source of AC power, and a plurality of load terminals configured to be connected to at least one electrical load; a detection assembly coupled to the plurality of line terminals and the plurality of load terminals, the detection assembly being configured to detect a wiring state associated with the plurality of line terminals and the plurality of load terminals, the detection assembly including a primary wiring state detection circuit coupled to the plurality of line terminals, and a secondary wiring state detection circuit coupled to the plurality of load terminals; and a circuit interrupting assembly including four sets of interrupting contacts that are configured to provide an electrically continuous path between the plurality of line terminals and the plurality of load terminals in a reset state and interrupt the electrically continuous path in a tripped state, wherein the plurality of line terminals and the plurality of load terminals are substantially isolated from each other in the tripped state.
