Track Busway Systems

Open-channel plug-in busway for flexible overhead power distribution.

USA TrackBusway manufactures two continuous-access, open-channel systems. Choose up to 40A per phase, per feed (T40) or up to 225A per phase, per feed (T225).

Both continuous-access systems let you expand power across your installation with additional feeds to electrically isolated sections of a run. We also offer splitters to reduce home runs and panel space. Each section retains its own rating.

Non-electrical joiners keep the sections mechanically connected without passing power between them.

The system rating is per feed. Each tap-off has its own marked current rating, voltage, pole count and protection requirements.

T40 and T225 tap-offs are not interchangeable.

Continuous Open-Slot Access

Enclosed conductors carry power along the overhead run. The continuous open slot lets compatible tap-offs connect at approved locations as equipment layouts change.

UL 857 listing information: Review Intertek records and model coverage for the 40A three-phase and 225A systems.

Match components to the selected system’s ratings and follow the product-specific installation and reconfiguration procedures.

Build the System: RUNs, FEEDs, and POWER

Select a compatible RUN, FEED, and POWER plug-in path for the chosen 40A or 225A system. Components, supports, and accessories must match the system family, approved connection locations, ratings, and project design.

Project-Specific Electrical Planning

Coordinate feed strategy, grounding, conductors, and final system selection before equipment is ordered or installed.

Splitter & Distributed Feed Planning

Coordinate feed quantity, type, and location with calculated load, conductor arrangement, equipment layout, voltage-drop requirements, protection, and approved drawings.

A splitter may support separately fed T225 sections when the engineered layout requires it; it does not increase the 225A-per-phase rating of an individual T225 run.

Grounding & Conductor Planning

Standard, Dedicated Ground, Isolated Ground (IG), 200% Neutral (N2), and 200% Neutral + Isolated Ground (N2IG) requirements are project-specific—not defaults on every system or component.

Coordinate the selected system, feeds, tap-offs, field wiring, voltage, loads, drawings, and electrical-engineer requirements.

Qualified Project Design

Confirm the complete project design before ordering:

  • Electrical basis: voltage, calculated load, phase and conductor configuration, ratings, protection and grounding.
  • Layout and components: feed arrangement, equipment layout, environment, compatible components, clearances, system condition and approved connection locations.
  • Installation and review: manufacturer instructions, qualified personnel, approved procedures, applicable electrical requirements and AHJ review.

Layout support does not replace the project electrical engineer, installer, or AHJ.

Site Review Before Installation

  • Mark the route, feeds, supports and maintenance access.
  • Identify moisture, dust or potential equipment impact so the designer can confirm suitability and protection.
  • Show planned equipment moves, tap-off positions, cord reach and loads.
  • Confirm the work sequence using the applicable T40 or 225A installation instructions.
