A busbar is provided for attaching a conductor to a support structure. The busbar can include a base wall and first and second side walls extending away from the base wall. A first flap can extend at an angle from the first side wall towards the second side wall and a second flap can extend at an angle from the second side wall towards the first side wall.

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.

Various implementations of grounding clamps and torque-controlled fasteners are disclosed. The grounding clamps may be used to attach grounding conductors to various structures, such as pipes, conduit, grounding rods etc. The torque-controlled fasteners may use various techniques to control the amount of torque applied to the fasteners used with the grounding clamps described herein.

An apparatus is disclosed. The apparatus has a decorative assembly stand having a cavity, a decorative assembly member that is configured to be removably received in the cavity, a coating that coats a surface of the decorative assembly member, a power socket including an electrical ground line, and a fastener. The electrical ground line is configured to be electrically connected to a surface of the decorative assembly stand. The fastener is configured to be received in an aperture of the decorative assembly stand and cut through the coating of the decorative assembly member and contact the surface of the decorative assembly member when the decorative assembly member is received in the cavity of the decorative assembly stand.

A joint fitting for an electrical conduit raceway may include a body including a first end and a second opposing end, at least one threaded section provided in the first end or the second end, at least one non-threaded section provided between the at least one threaded section and the corresponding first end or second end, the at least one non-threaded section defining a channel, and a sealing member positioned within the channel. Upon a radial compressive force being applied to the sealing member, at least a portion of the sealing member may protrude or extend from a terminal surface of the corresponding first end or second end.

The present disclosure provides descriptions of bonding connectors used to connect electrical conductors to metal structures. The bonding connector includes an electrically conductive body and an electrically conductive cap that can be releasably secured to the body using a fastener assembly.

A busbar is provided for attaching a conductor to a support structure. The busbar can include a base wall and first and second side walls extending away from the base wall. A first flap can extend at an angle from the first side wall towards the second side wall and a second flap can extend at an angle from the second side wall towards the first side wall.

A grounding connector for securing a wire or rod therein. The grounding connector has a body including a first side, a second side, and a mid-section extending therebetween, with an opening extending through the body from the first side to the second side. The body of the grounding connector includes a lock joint configured to join the grounding connector with a second grounding connector, with the lock joint including a recess inset into the mid-section of the body and a protrusion adjacent the recess extending from the mid-section.

An equipotential bonding system can be provided for a lightning protection system that includes a mast assembly with an internal passageway that includes an internal surface, and a conductor that extends through the internal passageway. The equipotential bonding system can include a deflection member that is disposed at least partly within the internal passageway. The deflection member can be configured to urge the conductor into contact with the internal surface to form a conductive pathway between the mast assembly and the conductor.

A clamping device (40) for providing an electrical connection between a subsea pipeline (1) and an electrical conductor (31). The device has a clamp element (41) comprising a first leg (41a) having a first leg end (41c) and a second leg (41b) having a second leg end (41d). The legs (41a, 41b) are configured to be provided on respective sides of the pipeline (1). The clamping device has a releasable tensioning device (48) connected to one of the legs (41a, 41b). The clamping device (40) has a first state, in which the ends (41c, 41d) of the first and second legs (41a, 41b) are provided at a first distance (d1) away from each other. The clamping device (40) has a second state, in which the tensioning device (48) is tensioned, causing the ends (41c, 41d) of the first and second legs (41a, 41b) to be at a second distance (d2) away from each other, the second distance (d2) being larger than the first distance (d1). The clamping device (40) has a template hole (42) provided in one of the legs (41a, 41b). The clamping device (40) comprises a connector member (44) provided in the template hole (42). The connector member (44) is mechanically connected to the clamp element (41). The clamping device (40) has a third state, in which the tensioning device (48) is released, causing the connector member (44) to be pressed towards the pipeline (1).
