Abstract:

A self-contained, hand-held device for detecting ground fault to the housing or casing of AC energized electrical equipment, appliances, tools or building wiring is described. A metal probe at one end of the device held against the conductive housing or casing of the equipment to be tested for ground fault applies, under ground fault conditions, a capacitively induced signal voltage to the conductive equipment housing in contact with the input circuit of the device operative to energize an output circuit including an indicator presenting a visual indication of ground fault.
