ABSTRACT:
A heating panel safety system has electrodes on opposite sides of the heating panel which supply conductive material. A first lead wire has ends connected to spaced terminals on a first electrode, and a second lead wire has ends connected to spaced terminals on a second lead wire. Turns in the lead wires are coupled via a core with a turn in a relay energizing wire. Normally closed circuit breaker contacts of the relay are opened when the relay is energized by a bias current in one of the lead wires, such as caused by a discontinuity in an electrode. Opening of the circuit breakers stops flow of current from a power source to the lead wires.
