Abstract:
1. A protective device comprising: a plurality of line terminals and a plurality of load terminals; a wiring state detection circuit configured to detect a wiring state associated with the plurality of line terminals and the plurality of load terminals, the wiring state indicating whether the plurality of line terminals or the plurality of load terminals are coupled to a source of AC power; a fault detection circuit coupled to the plurality of line terminals and configured to generate a fault detection signal in response to detecting at least one fault condition; an electronic switch actuator responsive to the wiring state detection circuit and the fault detection circuit; and a circuit interrupter coupled to the electronic switch actuator, the circuit interrupter including 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 being decoupled in a tripped state.
