Abstract:
1. An electrical wiring protection device comprising: a housing assembly including a plurality of line terminals, a plurality of load terminals, and a plurality of receptacle load terminals; a fault detection circuit coupled to at least one of the plurality of line terminals, the fault detection circuit being configured to generate a fault detection signal in response to detecting at least one fault condition; a first interrupting contact assembly coupled to the fault detection circuit, the first interrupting contact assembly including first interrupting contacts disposed between the plurality of line terminals and the plurality of load terminals, the first interrupting contacts being configured to electrically couple the plurality of line terminals and the plurality of load terminals in a reset condition, the first interrupting contacts being configured to decouple the plurality of line terminals from the plurality of load terminals in response to the fault detection signal in a tripped state; a wiring state detection circuit coupled to at least one of the plurality of line terminals, the wiring state detection circuit being configured to generate a first wiring signal when the plurality of line terminals are connected to a source of AC power; and a second interrupting contact assembly coupled to the wiring state detection circuit, the second interrupting contact assembly including second interrupting contacts disposed between at least one of the plurality of receptacle load terminals and at least one of a plurality of feed-through load terminals, the second interrupting contacts being 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.
