A system ( ) and method for canceling a leakage current is provided that uses line voltages (L , L ) that are out of phase with each other to produce a counter leakage potential that cancels leakage current. In one embodiment of the invention, the actual potential of the phases is measured ( ) and used to determine the counter potential that is to be applied to the line voltage (L or L ) that is generating the leakage current. The counter potential is applied to the appropriate line voltage by way of a transistor circuit (Q , Q ). The transistor circuit (Q , Q ) is controlled through standard electronic circuitry ( ), or by way of a microprocessor device ( ).
