Patent ID: 7813091

Claim:
A leakage current detector interrupter device comprising: at least one input conductor; at least one output conductor; a first switching element; a second switching element coupled to the first switching element; a third switching element coupled to the second switching element where at least part of the third switching element is electrically connected to the at least one input conductor of the device and another part of said third switching element is electrically connected to the at least one output conductor of the device and the at least one input conductor is electrically isolated from the at least one output conductor; and at least one external reference conductor; the first switching element, the second switching element and the third switching element being part of device circuitry having a point of reference different from a point of reference of said at least one external reference conductor of the device where the second switching element continuously energizes at least part of the third switching element causing said third switching element to electrically connect the at least one input conductor to the at least one output conductor wherein the point of reference for the device circuitry is different in voltage and phase from the point of reference of said at least one external conductor.
