ABSTRACT:
The present invention is directed to an electrical wiring protection device that includes a housing assembly having at least one line terminal and at least one load terminal partially disposed therein. A first conductive path is electrically coupled to the at least one line terminal. A second conductive path is electrically coupled to the at least one load terminal, the second conductive path being connected to the first conductive path in a reset state. A fault detection circuit is coupled to the first conductive path. The fault detection circuit is configured to generate a fault detection signal in response to detecting at least one fault condition. A wiring state detection circuit is coupled to the first conductive path. The wiring state detection circuit selectively provides a wiring state detection signal when the at least one line terminal is coupled to a source of AC power, and not providing the wiring state detection signal otherwise. An actuator assembly is configured to provide an actuation stimulus in response to the fault detection signal or the wiring state detection signal. A circuit interrupter is coupled to the actuator assembly. The circuit interrupter is configured to disconnect the first conductive path and the second conductive path in response to the actuation stimulus.
