Patent ID: 8526146

Claim:
An electrical wiring device comprising: line terminals and load terminals; at least one detection circuit including a circuit segment coupled between the line terminals and configured to conduct a predetermined signal in response to detecting a proper wiring condition, the predetermined signal not simulating a fault condition, a proper wiring condition being effected when the line terminals are connected to a source of AC power; an interrupting contact mechanism coupled to the at least one detection circuit, the interrupting contact assembly including four sets of interrupting contacts that are configured to provide electrical continuity between the line terminals and the load terminals in a reset state and configured to interrupt the electrical continuity in a tripped state, the interrupting contact assembly being substantially prevented from effecting the reset state absent the predetermined signal being conducted by the at least one detection circuit, the interrupting contact assembly being configured to effect the reset state without the occurrence of a simulated fault condition and subsequent to the predetermined signal; and a solenoid coil coupled to the interrupting contact mechanism, the solenoid coil configured to be substantially de-energized in the reset state and to be energized to effect the tripped state.
