Abstract
The present invention is directed to an electrical wiring protection device including a housing assembly including at least one receptacle, the at least one receptacle being configured to receive plug contact blades inserted therein. The housing assembly includes a hot line terminal, a neutral line terminal, a hot load terminal, a neutral load terminal, a hot user-accessible receptacle contact, and a neutral user accessible receptacle contact. A fault detection circuit is coupled to the hot line terminal and the neutral line terminal. The fault detection circuit is configured to detect at least one fault condition and provide a fault detect signal in response thereto. An interrupting contact assembly is coupled to the fault detection circuit. A weld breaker mechanism is coupled to the interrupting contact assembly. The weld breaker mechanism is configured to strike the first pair of contacts and/or the second pair of contacts in response to the tripping stimulus.
