ABSTRACT:
The present invention is directed to a protective device that includes a plurality of line terminals and a plurality of load terminals. A wiring state detection circuit is configured to detect a wiring state associated with the plurality of line terminals and the plurality of load terminals. A fault detection circuit is coupled to the plurality of line terminals and configured to generate a fault detection signal in response to detecting at least one fault condition. A circuit interrupter is coupled to the fault detection circuit. The circuit interrupter includes four sets of interrupting contacts configured to provide electrical continuity at least between the hot line terminal and the hot load terminal and the neutral line terminal and the neutral load terminal in a reset state. The four sets of interrupting contacts are open in a tripped state.
