Abstract
A ground fault circuit interrupt system with uncommitted contacts is provided which includes line-side system, phase, neutral and ground terminals electrically connectable to phase, neutral and ground terminals of an AC power source and load-side system, phase, neutral and ground terminals electrically connectable, respectively, to phase, neutral and ground terminals of an electrical load. The system includes a ground fault circuit interrupter including line- and load-side phase and neutral terminals for electrical connection to the line-side system, phase and neutral terminals for controlling a state of conduction of AC current between the source and electrical load in accordance with a detection of an interrupt condition. A relay switch is also included which has a relay coil and phase and neutral contacts such that line and load ends of the phase contact are electrically connected, respectively, to a GFCI load-side phase terminals and load-side system, phase terminal, line and load ends of the neutral contact are electrically connected, respectively, to a GFCI load-side neutral terminal and load-side system, neutral terminal; and the relay coil is electrically coupled between th…
