ABSTRACT:
A faulted indicator elbow-type termination connector for indicating the occurrence of a fault current in an electrical conductor of an alternating current distribution power system includes means for producing a magnetic field in response to an applied current to the electrical conductor. The termination connector includes a cylindrical body portion having a recessed housing section which projects radially from a central axis thereof. A faulted circuit indicator module is rotatably mounted within the recessed housing section and contains a trip setting device which is responsive to the magnetic field. The trip setting device has its sensitivity adjusted by rotating the faulted circuit indicator module relative to the cylindrical body portion. As a result, the sensitivity of the trip setting device can be changed quickly and easily so as to accommodate various trip settings.
