Abstract
A wall socket type ground fault circuit interrupter having a pair of sockets, a reset button and a test button that are accessible from the front of the interrupter. The interrupter has latched snap-acting contacts and a novel latching relay structure for releasably maintaining the snap-acting contacts in a circuit making position. The snap-acting contacts permit all of the components including the monitoring toroids and the power supply to be respectively located and connected at the load side of the snap-acting contacts so that all of the circuits of the interrupter are deenergized when the contacts snap to a circuit opening position. The snap-acting contact mechanism and relay are provided with structures which provides the interrupter with a trip-free mode of contact actuation and accordingly a tease-proof snap-acting contact operation.
