A support ring supports a welding ring to guide welding bugs around a coated pipe section. The support ring has a tubular body to support the welding ring, the body having substantially circular curvature around a longitudinal axis. At least one grounding extension connected to the body is offset longitudinally and radially outwardly with respect to the body and the longitudinal axis. This allows the grounding extension to lie radially outboard of a parent coating of the pipe section while the body encircles a cut-back end zone where the parent coating has been cut back. Pipe sections abutting end-to-end for welding can each be fitted with these support rings. This enables welding rings to encircle both of the cut-back end zones and allows effective grounding connections to be made without enlarging the cut-back end zones.

An anti-rotation flange (230) of the grounding stud (210) is received by an anti-rotation receiver (138) of the housing (120). The grounding stud (210) includes a first attachment feature (220) positioned between the first end (212) of the grounding stud (210) and the anti-rotation flange (230) and further includes a second attachment feature (260) positioned between the second end (214) of the grounding stud (210) and the anti-rotation flange (230). The housing (120) includes at least one guide (140) for rotationally orienting the anti-rotation flange (230) with the anti-rotation receiver (138).

A busbar is provided for attaching a conductor to a support structure. The busbar can include a main bonding wall, a first mounting wall extending away from a first end of the main bonding wall, a second mounting wall extending away from a second end of the main bonding wall. A first flap can extend at an angle from the first mounting wall towards the second mounting wall and the main bonding wall, or a second flap can extend at an angle from the second mounting wall towards the first mounting wall and the main bonding wall.

A grounding attachment for grounding an outer wall of a pole (13) made of a metal sheet covered on both sides by a coating layer of an electrically insulating material comprises a base element (1) of metal configured to be applied to bear on an inner wall of a pole in a state of use of the grounding attachment and at least one member (8, 9) of metal projecting from the base element and configured to be introduced into a hole in a wall of a pole in the state of use and to bear onto portions of the metal sheet defining the hole so as to establish an electrical contact thereto. The base element is provided with a connector member (4) enabling connection of the base element and by that the pole to ground.

A device for measuring physical quantities on electric conductors, comprising a casing suitable for assembly on the outside of the conductor via clamping and fastening means, a metallic punch that can be lodged in the metallic core of the conductor for taking measurements and sensing electronics associated to a printed circuit board wherein the metallic punch passes tightly through a support base, the sensing electronics made up of measuring chips encapsulated with multi-chip modular (MCM) technology being fastened on the outside of said support base. The measuring device is used in a remote control and management system of an electrical installation, to optimize the conditions of safety, consumption, energy efficiency, predictive maintenance and CO.sub.2 emissions; all this in industrial facilities, buildings and dwellings.

A shaft grounding device for establishing an electrically conductive connection between a rotatable shaft and a housing is mechanically and electrically connected to the housing. The shaft grounding device particularly includes contact elements, where each of the contact elements is elastically bendable and electrically conductive, and where the contact elements forming a sliding contact that is electrically conductive with a circumferential surface of the rotatable shaft or a sleeve on the rotatable shaft, with the the contact elements preloading the sliding contact. Additionally, the shaft grounding device includes at least one guide element, with each of the at least one guide element preventing the contact elements from folding over when the shaft grounding device is mounted onto the rotatable shaft.

A grounding element is provided. The grounding element includes a metal plate; and a metal block attached to the metal plate. The grounding element may be welded to a body or frame of a vehicle and used to provide a plurality of attachment points for a vehicle wiring harness.

An artificial lighted tree is presented with power routed through the trunk of the tree and three-wire safety grounding. The artificial lighted tree comprising a fused electrical plug having improved safety features comprising: a body portion surrounding respective first ends of a first, a second and a third electrical wire, the body portion further comprising a fuse holder embedded within an upper region of the body portion, and a fuse adapted to be releasably secured within the fuse holder via releasable securing means, a live blade in electrical communication with the first end of the first electrical wire, a neutral blade in electrical communication with the first end of the second electrical wire, a ground pin receptacle in electrical communication with the first end of the third electrical wire, wherein the body portion surrounds and maintains the live blade, neutral blade, and ground pin receptacle in spaced apart orientation corresponding to polarized sockets on an electrical wall outlet.
