ABSTRACT:
A ground fault receptacle having novel mechanical members for latching and moving the movable, circuit-breaking contacts, and for protecting against line-to-line arcing as the contacts make and break. The movable contacts are carried on a pair of conducting, self-biasing, spring arms which are held in a flexed position by a latch block which moves with the arms and is retained in position by a stem on the reset button and cooperating latch member. The parts are constructed and arranged to permit the use of relatively large test and reset buttons which are centrally arranged on the front of a duplex receptacle housing.
