  • Patent number: 9910078
    Abstract: A passive neutral fault current detection device fastened to cable television equipment detects the presence of a neutral fault within a subscriber's premises when the outer conductor of the coaxial cable is electrically bonded to the neutral conductor of the premises electrical service ground. In one example, the passive neutral fault current detection device employs a transformer circuit. The braided outer conductor of the coax cable acts as the primary coil of the transformer, and windings surrounding the coax cable act as a secondary coil. The windings are connected to an alert device to complete the circuit. As alternating current from a neutral fault flows through the braided sheath, a varying magnetic field is generated and impinges upon the secondary winding, which induces a varying voltage in the secondary winding. The voltage can drive the alert device which, in one embodiment, is a light emitting diode (LED).

  • Patent number: 8177563
    Abstract: 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.

  • Publication number: 20120088380
    Abstract: 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.

  • Patent number: 8106297
    Abstract: By providing a grounding conductor assembly affixed to a conduit bushing in a manner which enables the grounding conductor assembly to extend inwardly from the bushing, effectively being positioned coaxially with the inside diameter of the rigid metal conduit, conduit bushing is realized which enables all grounding wires to be quickly and easily mounted to the grounding conductor assembly. The conduit bushing of the present invention includes a generally circular shaped cover or cap member mounted to the terminating end of the conduit and incorporating an enlarged aperture which overlies the elongated passageway formed in the conduit. In this way, the electrical power carrying wires are able to extend outwardly from the rigid metal conduit into the desired outlet box, junction box with the grounding wire being quickly affixed to the receiving zone of the grounding connector assembly.

  • Publication number: 20110287643
    Abstract: In one embodiment, a bonding nipple for use in building electrical systems has a tubular-shaped body attached to a tubular-shaped head. The body and head share a common axis, and the outer diameter of the head is larger than the outer diameter of the body. The exterior of the body is threaded to form a male connector. The exterior of the head has a hole situated thereon to receive a grounding screw. In one exemplary installation, the body of the bonding nipple is fed through a punch-out of a service panel into one end of a female-threaded coupler, and the coupler is situated over a male-threaded conduit. The coupler is tightened over the conduit and the nipple until the wall of the panel is sandwiched between the coupler and the bonding nipple head. A wire is then connected between the grounding screw and a grounding bus bar in the panel.

  • Patent number: 8058879
    Abstract: A voltage indicating coupling for metal conduit systems to indicate the presence or absence of voltage on a wire enclosed by a section of electrical conduit for a grounded AC power distribution system. Through the use of two opposing rectifiers the National Electrical Code requirement that the entire metal conduit system be grounded is met. The voltage indicating coupling comprises a liquid crystal display (LCD), a static suppression resistor, two opposing rectifiers for grounding purposes, a plastic block housing and two clamping screws with corresponding wire terminals. At least one “hot” conductor enclosed by the section of electrical conduit is capacitively coupled to the conduit creating a complete circuit through the liquid crystal display (LCD), the static suppression resistor and the opposing rectifiers. The path around the circuit is completed by a ground connection on the grounded part of the conduit system, and the ground connection at the transformer.
