A grounding clamp having a conductive clamp body with an upper jaw and a lower portion with a through hole. A lower portion chamber includes an activator pivotally mounted on an axle. The activator includes a partially threaded upper pawl portion and a lower bar. An eyebolt with a threaded rod is slidingly disposed in the throughhole. A spring also mounted on the axle, urges the threads on the activator into engagement with the eyebolt rod. A conductive head is disposed on the upper end of the eyebolt, while a latching element is on the lower end. Pushing the activator lower bar pivots the activator and disengages the pawl from the threaded rod so that the threaded rod slides in the through hole freely until the conductive head engages a conductor. The clamp is easily tightened by turning the eyebolt and easily disengaged with only minimal reverse turning.

Systems, apparatus, and methods for use with an AC mitigation device coupled to an underground conductive structure and to one or more buried AC mitigation conductors adjacent to the underground structure. AC current transformers sense AC flowing between the mitigation device and the underground structure, and between the mitigation device and the mitigation conductors. A controllable switch is coupled between the mitigation device and the underground structure. Digitizing circuitry generates digital data corresponding to the AC sensed by the current transformers when the mitigation device is connected to and disconnected from the underground structure. Wireless communication circuitry processes signals received from a remote site to control the switch to selectively disconnect and reconnect the mitigation device from and to the underground structure to produce AC current signals indicative of mitigation device operation, and transmits the digital data to the remote site for processing to remotely test the AC mitigation device.

A clamp for supporting an electrical conductor on a structure and providing electrical continuity between the electrical conductor and the structure is provided. The clamp can include a mounting member with a through-hole and a strap, that can be configured to extend around the structure, coupled on one end to a first side of the mounting member and having a free end removably coupled to a second side of the mounting member. The clamp can include a clamping member with a through-hole and a main bolt extending through the through-holes of the mounting member and the clamping member. The main bolt can have a footer configured to contact the structure, which can be movable between a first configuration in which the footer is nested within a pocket of the mounting member and a second configuration in which at least a portion of the footer is positioned outside of the pocket.

An apparatus for electrically connecting a first structural member and a second structural member is disclosed. The apparatus has a first mating connector assembly configured to be attached to the first structural member, the first mating connector assembly including a first neutral terminal ring, a second mating connector assembly configured to be attached to the second structural member, the second mating connector assembly including a second neutral terminal ring, a first neutral lead electrically connected to the first neutral terminal ring, and a second neutral lead electrically connected to the second neutral terminal ring. The first neutral terminal ring is slidably disposed adjacent to the second neutral terminal ring when the first mating connector assembly and the second mating connector assembly are in contact. A first wall member forming the first neutral terminal ring includes a first plurality of slits.

An improved electrical power cord adapted to enhance the safety of an artificial lighted tree is presented. The electrical power cord has a three-prong safety grounded plug located at a first distal end of the electrical power cord, the plug electrically coupled to a multi-conductor cable comprising a neutral member, a hot member and a ground member. The electrical power cord also has a circuit protector connected in-line with the multi-conductor cable, the circuit protector including a fuse, or, a circuit breaker, having stationary and movable contacts operable between open and closed positions, and a manually operable reset button operably configured with the circuit breaker and electrically connected between said circuit breaker and the ground member for selectively actuating said circuit breaker for opening said movable contacts.

A 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.

A grounding pipe clamp secures a pipe and accommodates various attachment configurations to secure a range of conductor sizes. The grounding pipe clamp includes a bolt, a main body, and clamping pads. The bolt has a first leg and a second leg. The main body has a first end portion, a middle portion, and a second end portion. The first end portion has a slot that receives the first leg of the bolt. The second end portion has a L-shaped cutout that receives the second leg of the bolt to secure a pipe between the main body and the bolt. The clamping pads are secured to the first leg of the bolt and the second leg of the bolt. The clamping pads secure the conductors positioned on the main body.

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.

A grounding bushing with a central opening for electrically grounding a conduit, electrical metal tubing (EMT), or a pipe. The grounding bushing includes a stationary bushing portion and a rotatable bushing portion having slotted ends held together by mounting fasteners. The slotted ends permit rotation of the rotatable bushing portion away from the stationary bushing portion. After attachment to a conduit or similar structure, one or more mounting fasteners can be loosened to allow installation of additional wires through the central opening and into the conduit, EMT, or pipe. An electrically insulated liner extending around the entire inner periphery of the bushing prevents chafing or abrasion of any electrical wires by the end of the conduit.
