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 .
