ABSTRACT:
An indicator for flow of fault current in a conductor is enclosed in a housing carrying a metallic clamp for detachable mounting on the conductor. The indicator is operated by closure of a switch in response to flow of fault current in the conductor and is reset by the voltage developed between the clamp and ground. The indicator is checked by application of a permanent magnet to close the switch and an external voltage to reset the indicator. The indicator also can be reset by flow of normal current in the conductor employing a winding on a magnetic core surrounding the conductor and encapsulated with the switch.
