Abstract
A ground fault circuit interrupter comprises a reset key, a reset locking mechanism, a reset mechanism, a reset bracket, a bracket reset mechanism, a bracket homing mechanism, a reset linkage mechanism, and a reset linkage clutching mechanism. A conductive assembly is configured to selectively connect or disconnect electrical continuity between the power input side and the load side. The conductive assembly comprises pairs of short-circuit conductive strips with conductive movable contacts, power input connection assemblies with input conductive stationary contacts, wiring output assemblies, receptacle output assemblies with output stationary contacts, and a first short-circuit conductor and a second short-circuit conductor. A reverse wiring protection device comprises an electromagnetic generating device having a power supply sub-circuit configured with a reed switch connected in series, an electromagnetic actuator bracket with a pair of conductive pads, each pad having a movable contact, an actuator bracket homing mechanism, and a normally open holding switch.
