ABSTRACT:
A wedge clamp activator and circuit card extractor is provided for selective tightening and loosening of a wedge clamp on an electrical apparatus. The actuator includes a shaft for rotating the screw of the wedge clamp. The shaft is provided with pivot pins. A lever mounted to the pivot pins enables rotation of the actuator and the wedge clamp screw to which the actuator is attached. The lever includes a fulcrum dimensioned for engagement with a rigid support on the electrical apparatus. The lever may be translated into a position where the fulcrum engages the support. The lever may then be rotated about the fulcrum for extracting the circuit to which the wedge clamp is mounted from the electrical apparatus.
