摘要： A receptacle for a power circuit includes a receptacle housing, a line terminal structured to receive a voltage including one of a nominal voltage and a greater excessive voltage, a load terminal, a neutral terminal, a load neutral terminal, separable contacts electrically connected between the line and load terminals, an operating mechanism structured to open and close the separable contacts, and a trip mechanism cooperating with the operating mechanism to trip open the separable contacts. The trip mechanism includes a trip circuit structured to detect a first trip condition associated with the power circuit and to responsively actuate the operating mechanism to trip open the separable contacts. The trip mechanism also includes an overvoltage circuit structured to detect a sustained excessive voltage condition between the at least one neutral terminal and the line or the load terminals and to responsively actuate the operating mechanism to trip open the separable contacts.
