Abstract

The present invention is directed to an electrical wiring protection device that includes a housing assembly having a hot line terminal, a neutral line terminal, a hot load terminal, and a neutral load terminal partially disposed therein. A miswire detection circuit is coupled to the hot line terminal, the neutral line terminal, the hot load terminal, and the neutral load terminal. The miswire detection circuit is configured to generate a miswire fault condition when AC power is coupled to the hot load terminal and the neutral load terminal and open circuit when AC power is coupled to the hot line terminal and neutral line terminal. A fault detection circuit is coupled to the miswire detection circuit. The fault detection circuit is configured to generate a fault detection signal in response to detecting at least one fault condition. The at least one fault condition including the miswire fault condition. An interrupting contact assembly is connected to the fault detection circuit. The interrupting contact assembly includes interrupting contacts that provide electrical continuity between the hot line terminal and the hot load terminal, and the neutral line terminal and the neutral load terminal in a reset condition. The interrupting contact assembly is also configured to open the interrupting contacts in response to receiving the fault detection signal.
