225A Track Busway System for Plug-In Power

T225 is USA TrackBusway’s higher-capacity, open-channel busway system for flexible overhead power distribution. Its continuous plug-in slot provides connection points along the run for compatible outlet boxes and drop cords.

Higher-Capacity Power.
Continuous Plug-In Access.

Up to 225A per phase, per feed.
Up to 600 Vac.

Inside T225’s aluminum housing, U-shaped copper busbars sit in a continuous insulator. Electrical joiners connect the busbars between sections; mechanical couplers secure the housings. Compatible tap-offs insert through the open slot and rotate to engage the busbars, delivering power to outlet boxes and drop cords along the run.

Add or relocate outlet boxes and drop cords along the run, within the system’s installation and clearance requirements. Each tap-off has its own voltage, current and protection rating.

Listed to UL 857 Busway Standards. Standard and 200% Neutral (N2) busway and end-feed configurations are included in the T225 listing. Review model scope and ratings. The 600V system maximum does not make every tap-off or receptacle suitable for 600V.

Runs & Splitters

Choose run length, PowerDrops and feeds, then add a splitter junction box to explore the layout and component pricing.

Need more capacity across a row? A coordinated 450A-per-phase splitter layout can supply two separately protected 225A feed circuits. Each serves its own electrically separate section or run; each section remains limited to 225A per phase.

Splitting does not increase a section’s rating or create extra source capacity. Coordinate the supply, section boundaries, overcurrent protection, fault current and loads with the project design.

Choose Your T225 Busway Lengths & Conductor Configuration

Available in 5 ft and 10 ft lengths. Build the overhead run with straight sections, then choose Standard, 200% Neutral, Isolated Ground, or 200% Neutral + Isolated Ground.

Blue: neutralAmber: isolated groundGreen: housing ground
S

Standard

Three phases and neutral. The bonded aluminum housing provides the equipment-grounding path.

N2

200% Neutral

Adds neutral copper for 200% neutral. Equipment grounding remains through the bonded housing.

IG

Isolated Ground

Adds a separate isolated-ground conductor alongside the phases and neutral. The housing remains grounded.

N2IG · BOTH OPTIONS

200% Neutral + Isolated Ground

Combines both options: 200% neutral and a separate isolated-ground conductor. The housing remains grounded.

Model-based cutaways. Colored callouts identify the conductors; they do not represent physical insulation colors. Click a diagram to enlarge the labels. Match the lengths, feed and electrical joiners to one conductor configuration and coordinate compatible tap-offs. Standard and N2 lengths are included in the public T225 listing; confirm the selected IG or N2IG configuration and listing scope.

How a T225 Run Comes Together

This example uses two 10 ft straight sections, plus the end feed’s short T225 section. Electrical joiners continue the conductor path; mechanical couplers secure the adjoining housings.

Two 10-foot T225 lengths, an end feed with a short busway section, two joiner connections, five suspension hangers, rear feed-bracket support and one end cap From left to right: gold end feed supported at its rear L-bracket, attached short T225 section, first red joiner, blue 10-foot length, second red joiner, blue 10-foot length, purple end cap. One suspension hanger supports the short feed section, and two support each 10-foot length. The rear feed bracket is also supported. Colors identify components only, not finishes or circuits.

Optional Critical Power Monitoring for 225A Track Busway

Optional monitoring may be specified at feeds or tap-offs. Confirm the hardware, power supply, communications interfaces, supported functions, and applicability in the approved project submittal.

Tap-Offs for 225A Track Busway

T225 Bus Plugs & Tap-Off Units

Choose compatible T225 bus plugs (tap-off units) for 225A Track Busway. Select a 1-, 2- or 3-pole outlet box or drop cord to match the equipment connection.

T225 identifies the busway family; each tap-off has its own marked rating. Circuit-breaker or Class CF CubeFuse protection depends on the selected assembly and approved project documentation.

Need power that retracts when the work is done?

A breakered cord reel brings 120V power within reach, then returns the cord overhead when it is not in use.

Busway support requires threaded rod larger than 1/4 in. nominal diameter. 1/4-20 rod is not permitted. Choose the reel that matches your busway family. All receptacles on each reel share one 120V, 20A branch.

Inside the 225A Track Busway System

Three phases + neutral. One continuous plug-in channel. The tap-off fitting engages the busway conductors used by its circuit. Your supply and conductor selection determine the available voltage; the tap-off does not convert voltage.

Supply examples require matching rated assemblies. The standard four-wire system is L1, L2, L3 and N; its bonded aluminum housing provides the separate equipment-grounding path. Gold shows the contacts used by the example circuit; unused pins are omitted. The 2- and 3-pole examples omit the neutral contact, which is included where the specified connection requires it. These simplified, model-based cutaways explain conductor selection; use selected-unit drawings for actual contacts and wiring.

Choose the access style your layout needs

  • Continuous-access T225: Position compatible tap-offs along the run as equipment layouts change, within the system’s ratings and installation requirements.
  • Fixed-location plug-in busway: Connect tap-offs at designated positions where those locations suit the equipment layout.
  • Feeder/backbone busway: Carry power between distribution equipment. A vertical riser is an application that requires a system designed for that installation.

Confirm loads, voltage, protection, available fault current and clearances against current ratings and drawings.

225A Track Busway is used where overhead power distribution must support heavier equipment, changing layouts, or multiple equipment zones. Common applications include data centers, industrial manufacturing plants, logistics and distribution facilities, automotive assembly areas, robotics cells, research laboratories, and flexible commercial environments where equipment layouts evolve over time.
