an adjustable ground clamp for easy positioning onto electric conduits of different diameters and grounding multiple electrical devices . a first and a second jaw are pivotally connected and have differently angled jaw surfaces . a distal end of the first jaw has an elongated hole and a distal end of the second jaw has a curved fork having a slot for receiving a bolt with a cylindrical nut . a fastener connects a ground conductor or wire to the ground clamp . a terminal block accepts ground conductors from multiple different electrical devices . the jaws may be easily separated for placement of an electrical conduit without separating or detaching any parts from the ground clamp , making attachment to an electrical conduit quick , easy , and secure . the terminal block permits different electrical devices to be grounded with a single ground clamp .
