Patent ID: 8514529

Claim:
An electrical wiring device comprising: a plurality of line terminals configured to be connected to a source of AC power, and a plurality of load terminals; a detection assembly coupled to the plurality of line terminals and the plurality of load terminals, the detection assembly being configured to detect a wiring state associated with the plurality of line terminals and the plurality of load terminals, the detection assembly including a primary wiring state detection circuit, a secondary wiring state detection circuit, and an isolation circuit disposed therebetween, the isolation circuit being configured to electrically isolate the line terminals from the secondary wiring state detection circuit in a tripped state; a circuit interrupting 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 the tripped state, the circuit interrupting assembly being substantially prevented from effecting the reset state absent a predetermined successful proper installation signal from the primary wiring state detection circuit.
