The disclosure provides an insulator for an end of a cable, the insulator having a longitudinal body in which a central channel is provided, the insulator including a connector system arranged in the central channel, the system comprising a connection pin for receiving an end segment of the cable, the pin being shaped so as to present an inside surface that is serrated.

A mechanical grounding clamp including a body, having an upper plate defining a threaded hole therethrough and having an outer surface, a lower plate spaced apart from the upper plate and having an inner surface, and a connecting plate connecting the upper plate to the lower plate, a fastener mateable with the threaded hole in the upper plate and having a proximal end and a distal end, the distal end extendable through the threaded hole of the upper plate and toward the inner surface of the lower plate. There may be a nut on the fastener for driving toward the upper plate to secure a grounding conductor to the body.

A modular plug-in bus wiring system for electrical connections. The system includes an adapter module, the adapter module including at least a housing wherein the housing includes a front side containing at least an electrical connector, a back side, an upper end, a lower end, and at least a receptacle. The system includes at least a plug configured to insert in the at least a receptacle wherein the at least a plug is connected to at least a cable that includes at least an electrically conductive wire. The at least a plug includes a ventral surface, a dorsal surface, a first side and a second side.

A bonding lug assembly includes a bonding lug and a set screw. The bonding lug includes a body that defines a first channel and a second channel. The first channel defines a first conductor path extending in a first direction, and the second channel defines a second conductor path extending in a second direction that is different from the first direction. The set screw is configured to selectively engage the bonding lug and retain a bonding conductor within at least one of the first channel or the second channel.
