Patent ID: 7133266

Claim:
An electrical wiring protection device comprising: a hot line terminal, a neutral line terminal, a hot load terminal, and a neutral load terminal; a miswire detection circuit coupled to the hot line terminal, the neutral line terminal, the hot load terminal, and the neutral load terminal, the miswire detection circuit being 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 coupled to the miswire detection circuit, the fault detection circuit being 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; and an interrupting contact assembly connected to the fault detection circuit, the interrupting contact assembly including 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 being configured to open the interrupting contacts in response to receiving the fault detection signal.
