ABSTRACT:
The present invention is directed to an electrical wiring protection device that includes a housing assembly having a plurality of line terminals and a plurality of load terminals. A fault detection circuit is coupled to at least one of the plurality of line terminals and configured to generate a fault detection signal in response to detecting at least one fault condition in the electrical distribution system. A circuit interrupter is coupled to the fault detection circuit. The circuit interrupter is configured to couple the plurality of line terminals to the plurality of load terminals to form a conductive electrical path in a reset state, and decouple the plurality of line terminals from the plurality of load terminals in response to a fault detection signal in a tripped state. A voltage transient suppression circuit is coupled to at least one of the plurality of line terminals. The voltage transient suppression circuit is configured to generate a signal simulating the at least one fault condition in the event of failure.
