ABSTRACT:
A universal ground clamp is employed for clamping to a ground electrode such as a conduit, a pipe or a rod by means of a clamp strap. The ground wire is secured by means of a set screw in an aperture of a head which extends from a threaded shank. A platen, which has a convex bowed surface, is retained against rotation by retainer flanges of a contact member. The platen is clamped against the strap to secure the ground clamp in position. The clamp may be mounted and the ground wire secured by applying a torque from one side of the ground clamp.
