A fault indicator for indicating the occurrence of a fault current in an electrical conductor is mounted on the test point of an elbow connector of the type commonly used in power distribution systems. An integral collar assembly encircles the connector housing to capacitively couple the fault indicator circuitry to the system conductor within the connector. The collar assembly includes an inner magnetic core which establishes the coupling and an outer core which shields the inner core from magnetic fields resulting from fault currents in adjacent conductors.
