Abstract: The present invention is directed to a device that includes a housing assembly including a plurality of line terminals, a plurality of load terminals, and a plurality of receptacle load terminals coupled to the plurality of load terminals by a plurality of conductors. A circuit interrupting assembly is disposed in the housing and coupled to the plurality of line terminals or the plurality of load terminals, the circuit interrupting assembly establishing electrically continuity between the plurality of line terminals and the plurality of load terminals in a reset state and interrupting the electrical continuity between the plurality of line terminals and the plurality of load terminals in a tripped state. A wiring state detection circuit is coupled to the plurality of line terminals or the plurality of load terminals. At least one switchable element is coupled to the wiring state detection circuit, the at least one switchable element including a plurality of switching states.

Abstract: The present invention is directed electrical wiring protection device that includes a housing assembly having line terminals, load terminals, and receptacle terminals. A fault detection circuit is configured to generate a fault detection signal in response to detecting fault conditions. First interrupting contacts are configured to electrically couple the line terminals and the load terminals in a reset condition and decouple the line terminals from the load terminals in response to the fault detection signal in a tripped state. A wiring state detection circuit is coupled to at least one of the line terminals. The wiring state detection circuit is configured to generate a first wiring signal when the line terminals are connected to a source of AC power. Second interrupting contacts are configured to electrically couple the at least one receptacle load terminal to the at least one load terminal in response to the first wiring signal.
