Continuous plug-in busway refers to a busway system that allows plug-in access along the run, so power can be added or repositioned where it is needed without cutting conduit or rewiring.
UL 857 Definition: In the United States, UL 857 defines continuous plug-in busway systems as 225 amps or less.
USA TrackBusway operates within this UL 857 range, with busway lengths manufactured up to 225A per phase and a distributed feed design that allows power to be added anywhere along the run.
Effectively distribute power above your facility for easy modifications and expansions that require little-to-no downtime.
Power is distributed through insulated copper busbars housed inside the USA TrackBusway®, allowing plug-in access at any point along the run without cutting conduit or rewiring.
Accessible Overhead Power:
Unlike a traditional pipe-and-wire system, The Track Busway system includes a continuous access slot to tap power at any point along the Track Busway system.
This plug-in busway system supports powertaps at multiple voltages, with customizable plug-ends to fit a variety of configurations.
Scalable Overhead Power:
The Track Busway system can be thought of like a power highway, designed to efficiently get power all across a facility, while allowing for easy expansions.

Pole count refers to the internal breaker configuration of the plug-in unit; the Track Busway provides a full conductor set including neutral.
For example, a 3-pole plug-in may be installed on a four-conductor (3-phase, L-L-L-N) Track Busway to serve three-phase loads with a neutral present.
Compatible with 120 V, 208 V, or 480 V Power Supports three-phase, four-wire configurations with line-to-line voltages up to 480 V. Ideal for powering equipment in warehouses, assembly lines, and production areas. Plug-in tap-offs can be repositioned without re-wiring or permitting. Optional isolated-ground tap-offs available for sensitive loads.
