Abstract
A high current ground fault circuit interrupter has an induction sensor mounted on the device remote from the ground fault circuit interrupter circuitry in such a manner as to allow cables capable of carrying larger currents than the current carrying capability of the contacts in the interrupter circuitry to be passed therethrough. The induction sensor carries a differential transformer for sensing line to ground faults and a neutral transformer for sensing neutral to ground faults. It makes use of an external contactor whose coil is engaged by contacts of the ground fault circuit interrupter to interrupt the cables carrying the high currents, even at a distance somewhat remote from the ground fault circuit interrupter. The induction sensor has the capability of carrying therethrough cables of 240 volts AC line to ground or line to line.
