A joint sleeve is proposed for connecting busbar sections, each having connectable contacts. In an embodiment, the sleeve includesa non-magnetic case defining butt ends occluded with non-magnetic flanges each having a hole securing the respective busbar section therein,a fire-resistant coating covering the case,an electrically insulated supporting tube disposed within the case and defining a chamber therein, enclosing the connectable contacts,a grounding screen mounted on the supporting tube, anda fire-resistant layer disposed between the case and the screen capable of thermal expansion upon heating thereof, thereby improving fire-resistance. Instead of the fire-resistant layer, another embodiment includes an annular air chamber formed between the case and the supporting tube, while the annular chamber is in communication with hollows, and the supporting tube is closed by another pair of flanges with holes securing the respective busbar sections. The sleeve allows for improving fire-safety of power consuming facilities.

Connectors including apertures for grounding outer conductors of conduits and connectors including grounding grooves for grounding outer conductors of conduits are disclosed. In some embodiments, a connector includes a bore, a gripping portion axially surrounding the bore, a generally cylindrical aperture for receiving a grounding wire, and a securing port for securing the grounding wire in the aperture. An exterior gripping surface of the gripping portion is symmetric. The generally cylindrical aperture extends along an aperture centerline through at least a portion of the gripping portion. The securing port extends along a securing port centerline and intersects the generally cylindrical aperture. In other embodiments, a connector includes a grounding groove extending at least partially around an outer diameter of the connector that is adapted to receive the grounding wire, and a securing port longitudinally offset from the grounding groove and extending along a securing port centerline.

A temporary grounding assembly is provided that includes a ground clamp, a tensioning member, a tensioner device, a first conductor, and a ground rod. The ground clamp has a main body with a plurality of teeth that are configured to make electrical connection with an outer diameter of a pipe. The tensioning member is secured to one end of the ground clamp. The tensioner device is securable to the tensioning member and to an opposite end of the ground clamp. The first conductor is in electrical connection with the ground clamp. The ground rod is in electrical connection with the first conductor.

A ground cone for providing electrical contact to an interior of a conduit is provided. The ground cone includes a cone body including one or more tabs positioned on the cone body and extending radially outward from the cone body, the one or more tabs positioned separately from one another. At least one of the one or more tabs has a helical edge, the helical edge shaped to be received in a groove of a thread. The cone body includes a cap end and a bottom end opposite the cap end. The ground cone also includes a cap extending longitudinally from the cone body at the cap end and extending toward the bottom end. The cone body and the cap define a channel sized to receive an end of a conduit therein.

A joint sleeve is proposed for connecting busbar sections, each having connectable contacts. In an embodiment, the sleeve includesa non-magnetic case defining butt ends occluded with non-magnetic flanges each having a hole securing the respective busbar section therein,a fire-resistant coating covering the case,an electrically insulated supporting tube disposed within the case and defining a chamber therein, enclosing the connectable contacts,a grounding screen mounted on the supporting tube, anda fire-resistant layer disposed between the case and the screen capable of thermal expansion upon heating thereof, thereby improving fire-resistance. Instead of the fire-resistant layer, another embodiment includes an annular air chamber formed between the case and the supporting tube, while the annular chamber is in communication with hollows, and the supporting tube is closed by another pair of flanges with holes securing the respective busbar sections. The sleeve allows for improving fire-safety of power consuming facilities.

An artificial lighted tree is presented with power routed through the trunk of the tree and three-wire safety grounding. The tree is divided into sections for easy assembly, disassembly, and storage. The base of the tree is grounded through a three-prong safety grounded electrical cord and each section of the tree makes a ground connection with the base section as it is assembled to the artificial lighted tree. Electrical connections to power the lights may be made outside the trunk of the tree or through electrical connections within the tree.

A bonding kit for use with a water-holding structure, the kit having a bonding conductor with a body portion configured to reside within a component attached to the water-holding structure. The bonding conductor includes an extension portion configured to extend outwardly from the component. The bonding kit includes a conductor fitting configured to attach to the extension portion of the bonding conductor and to attach to a conductive system of the water-holding structure, providing an electrical connection between the bonding conductor, or water therein, and the conductive system, the bonding conductor providing equipotential bonding for water contained in the water-holding structure.

A coupling for connecting pipe ends, comprising a hollow body with an entrance for each pipe end provided with a radial seat for a pipe end and a coupling nut for clamping the pipe end, whereby an electrically conductive bridge is provided, which at the location of the seats is provided with a clamping element that is elastically deformable in the radial direction with respect to the respective seat, and is provided with a contact section, which in a rest situation is at a distance from the axis of the seat that is smaller than an outside radius of the pipe end for which the seat concerned is intended.

A clamp assembly for securing a conductor can include a first plate with a first groove having a first width transverse to a first groove axis and a first protrusion extending away from the first groove and forming a recessed channel disposed outside of the first groove. The clamp assembly can further include a second plate with a second groove having a second width transverse to a second groove axis and a pair of second protrusions extending away from the second groove, each second protrusion of the pair forming a recessed channel disposed outside of the second groove. In an installed configuration the first protrusion is arranged between the pair of second protrusions relative to an elongate direction of the first and second grooves to deform the conductor around the first protrusion.
