A bus bar including a main tubular body extending along a longitudinal axis between a first end and a second end, the main tubular body being made of a first electrically conducting material for carrying an electrical current therealong, and the bus bar further including a hollow connection body longitudinally projecting from the first end of the main tubular body and provided with a mounting surface for receiving an electrical connector thereto, the hollow connection body being made a second electrically conducting material for carrying the electrical current between the electrical connector and the main tubular body.

Disclosed is an elastic plug-in jaw structure for a tap-off unit. The elastic plug-in jaw structure for the tap-off unit includes a plug-in jaw and a flexible connector connected to the plug-in jaw. The plug-in jaw can be connected to a lead-out conductor in the tap-off unit through the flexible connector. An elastic member is arranged at a rear side end of the plug-in jaw. A pressing member abuts against a rear side of the elastic member. The pressing member is configured to elastically press against the plug-in jaw through the elastic member, to facilitate a direct electrical connection between the plug-in jaw and a busbar conductor.

A track busway power distribution unit including a housing, a power input coupled with the housing and connectable to an electrical busway, a securement mechanism moveably coupled to the housing and structured to secure the power distribution unit to the electrical busway, and at least one outlet module located at least partially within the housing. The outlet module can include at least one outlet core having a core outer surface configured to mate within a first connector type. The outlet core can include a plurality of electrical terminals each coupled to the power input and configured to connect with mating terminals corresponding to both the first connector type and a second connector type that is different than the first connector type. A removable shroud can be positioned around the outlet core, wherein the shroud includes a shroud inner surface configured to receive the first connector type.

A tap-off box includes an enclosure defining a plurality of stab slots and defining a wire access opening, and a thermocouple disposed therein. The tap-off box is configured for remote control and monitoring.
