  • Releasable sensor for conductor fault detection including a rigid trigger arm
    Patent number: 5397982
    Abstract: A faulted circuit sensor is disposed in a releasable and reusable clamp mountable on an electrical conductor. The clamp includes a body for receiving the faulted circuit sensor indicating circuitry, and a pair of hinged fingers which actuate over the conductor to grip the clamp to the conductor and align the fault indicating circuitry with respect to the conductor. The fingers include a triggering arm which causes the arms to engage over the conductor when the conductor is properly aligned in the proximity of the clamp.
