USA TrackBusway® vs Starline* Track Busway
Both manufacturers’ track busway systems use open-channel designs that allow compatible power tap-off units to be added, moved or repositioned.
Higher-ampacity product families offer more capacity through an individual feed. USA TrackBusway® focuses on additional power feeds and splitter-based layouts that put capacity where it is needed across an installation. Each electrically isolated section retains its own rating.
T225 is the 225A-per-phase track busway system manufactured by USA TrackBusway®. It combines busway lengths, feeds, joiners, and repositionable tap-off units in a modular system that adapts as layouts evolve.

How separate feeds serve one physical row
In this T40 installation, an 80A-per-phase splitter supplies two separately protected 40A sections. The non-electric joiner marks where one section ends and the next begins. Each section retains its 40A-per-phase rating.

Comparing Overhead Plug-In Track Busway Systems
Both systems are designed for overhead plug-in power access, but they are often considered for different planning priorities. USA TrackBusway is built around practical 40A and 225A layouts, factory-direct project support, and feed placement planned around real load locations.
Higher-ampacity track busway families can carry more power through one feed. USA TrackBusway can serve a larger total project load through additional feeds to electrically isolated sections, with splitters where appropriate. Plan the supply and protection around each section and its equipment loads.

KEY SIMILARITIES
Both track busway systems use a continuous plug-in architecture that allows tap-off units to be positioned along a run more flexibly than conduit-and-junction-box layouts. This shared plug-in open-channel approach is what enables faster changes and easier repositioning of loads.

Frequently Asked Questions About Track Busway
For additional answers about plug-in busway safety, standards, reconfiguration, and installation, visit the
How do continuous-access, fixed-location plug-in and feeder busway differ?
When outlets may move, consider continuous-access busway. Compatible tap-offs can be repositioned along the open channel. For predictable outlet locations, compare fixed-location plug-in busway, which has designated tap-off points, with conduit runs to fixed outlets. For bulk power between distribution points, evaluate feeder busway. Both USA TrackBusway and the Starline families compared here offer continuous access. Compare busway architectures and conduit →
When does track busway make sense for a changing lab?
When benches move or instruments change, repositionable tap-offs let power connections follow the equipment. Consider T40 when the planned load on each phase and the largest instrument circuit fit the selected feed and tap-offs. If more capacity is needed, evaluate T225 against those same two requirements. See the worked lab bench examples and T40 and T225 product documents.
What voltage options are supported by Track Busway?
USA TrackBusway supports common facility voltages including 120V, 208V, 240V and 480V, with compatible 1-, 2- and 3-pole tap-offs. T225 is rated up to 600 Vac. Available load voltages depend on the supply, conductor arrangement and selected components; every tap-off and receptacle has its own rating.
How does Track Busway comply with UL standards?
USA TrackBusway T225 is Listed to UL 857 Busway Standards. The public listing includes Standard and N2 busway/feed configurations. Confirm the selected build’s ratings and listing coverage, including any IG/N2IG configuration.
