A high current grounding assembly especially adapted for electrically interconnecting and grounding substation phase busses conductors is provided which includes rigid metallic connector elements capable of handling extremely high fault current loads without violent whipping or other motions. The clamp and connector assembly, or one of the phase busses, is connected to ground in order to protect linemen or other workers in the vicinity of the assembly from the effects of fault or inductive currents. In preferred forms, novel conductor-gripping clamps and rigid tubular connector elements may be partially or completely preassembled and thereafter installed on phase busses. The clamps include a shiftable gripper for engaging a respective phase conductor, with a pair of transversely disposed clamp sections on the underside of the gripper for receiving and gripping the rigid connector elements; this construction presents the shortest possible current path through the clamps, which is important when very high fault currents or the like must be grounded.
