The ground wire is secured to the ground wire fixture, and with the adapter collar secured to the armored conduit, electrical ground continuity is extended from the flexible cable to the armored conduit. With the removable cover secured over the access aperture, exposure of the ground wire clamp and the conductors of the flexible cable is eliminated.Type: GrantFiled: December 23, 2010Date of Patent: October 30, 2012Assignee: Metis Holdings LLCInventor: James A Vaughan

Patent number: 8231392Abstract: An electrical grounding device includes a first collar member having first inner and outer wall surfaces, a first flange projecting from the first inner wall surface, and a first shoulder projection extending radially from the first outer wall surface. The device further includes a second collar member having second inner and outer wall surfaces, a second flange projecting from the second inner wall surface, and a second shoulder projection extending radially from the second outer wall surface. Further, the device includes a thickened wall region including an aperture passing transversely therethrough, wherein the thickened wall region is disposed in the outer wall surface of at least one of the first and second collar members. A fastener is operably associated with the first and second shoulder projections to removably couple the first and second shoulder projections together.Type: GrantFiled: August 13, 2010Date of Patent: July 31, 2012Inventor: Barton L. Garvin

Patent number: 8177563Abstract: A ground fitting allows electrical connection between a ground wire carried in a metal sheathing, and a ground point such as a water spigot on a short pipe extending from a wall. The pipe clamp is tightened on the short pipe or ground rod. The metal sheathing is cut to expose a short length of ground wire. The ground wire is inserted into the wire clamp, and the metal sheathing is inserted between a clamping plate and clamp seat at the near end of the wire clamp. A ground screw is tightened against the ground wire to hold the ground wire in the wire clamp and plate screws securing the clamping plate are tightened to secure the sheathing between the clamping plate and clamp seats. The wire clamp is attached to the pipe clamp selectively parallel or perpendicular to the short pipe or ground rod to compete the ground fitting.Type: GrantFiled: October 27, 2010Date of Patent: May 15, 2012Inventor: Mike Vernica

Publication number: 20120088380Abstract: 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.Type: ApplicationFiled: September 8, 2011Publication date: April 12, 2012Inventor: Lawrence J. SMITH
