Abstract

A method for limiting current in an electrical circuit (10) having transmission wires (18, 20) for power transmission includes determining whether an unexpected operating condition exists along the transmission wires and limiting the current to prevent the damage caused by an unexpected operating condition. If the unexpected operating condition persists, the method may disable the electrical circuit.
