Abstract
A technique to limit energy in inline wiring faults. The technique employs a device which detects the presence of the fault by sensing voltage at the load end of a circuit that is at risk for an inline arcing fault. Upon detecting the drop in voltage at the load end of the feeder circuit the device acts to interrupt the current in the circuit loop feeding the fault. This action reduces the energy delivered to the fault. This technique is of value in any circuit and results in a substantial reduction in fault energy when employed in a DC circuit feeding an inductive load with a freewheeling diode.
