225A Track Busway power feed units connect facility power to a USA TrackBusway T225 overhead busway run. The end-feed enclosure provides the connection point between the incoming electrical supply and the busway conductors. Match the feed to the selected conductor configuration, with optional Schneider critical power monitoring available for each feed type.

How to Choose
Choose Standard for normal 3-phase + neutral layouts. Choose IG for isolated ground, N2 for 200% neutral, or N2IG when both are required. Then select No Power Monitoring or Critical Power Monitoring.

T225 Feed Integration and Certification
Plan the feed location together with the source panel, busway route, connected loads, and project drawings. A feed serves its coordinated 225A run. See the 20-foot straight-row component example; larger installations can use separately protected runs for different equipment areas or project phases.
The selected feed, adjoining lengths, and tap-off units must share the specified conductor arrangement. Review the product data sheet and electrical design before ordering, including whether the project needs monitoring at the feed or selected downstream points.
EF225 Power Feed Certification
The Intertek listing covers Standard (S) and 200% Neutral (N2) EF225 end-feed configurations to UL 857 and CSA C22.2 No. 27.
See certification details for applicable models and configurations.

Planning Feeds for Multiple 225A Runs?
For larger layouts, plan separate, protected 225A runs around equipment zones, project phases, and future expansion. Splitter layout planning helps coordinate the incoming supply and downstream feed locations.
Multiple feeds require coordinated electrical design, including sectioning, overcurrent protection, conductor continuity, and load calculations. Do not parallel feeds onto one continuous energized run.
Conductor Configuration
Choose Standard, Isolated Ground (IG), 200% Neutral (N2), or 200% Neutral + Isolated Ground (N2IG) to suit the project.
Match the feed, busway lengths, and tap-off units to the selected configuration and approved electrical drawings.

Frequently Asked Questions
A 225A power feed unit brings building power from the source panel or distribution equipment into the Track Busway run. It must match the busway conductor configuration and project electrical requirements.
Choose Standard for typical 3-phase + neutral layouts. Choose IG where isolated ground is required. Choose N2 where 200% neutral is required. Choose N2IG when both 200% neutral and isolated ground are required.
Standard (S) and 200% Neutral (N2) busway and feed configurations are included in the public T225 listing. For IG or N2IG orders, review the listing scope and confirm the selected configuration before specifying.
Feed placement should be coordinated with the source panel, system layout, voltage drop, tap-off density, access, project drawings, and future expansion plans. For larger 225A layouts, USA TrackBusway can help review whether the feed should be located near the beginning of the run, closer to a load zone, or within an intentionally separated section.
Yes. Multiple feeds can be used where the layout is intentionally divided into separately fed sections. This can be useful for larger layouts, phased expansions, or equipment zones with different power requirements. Feed strategy must be coordinated with the project electrical design, overcurrent protection, conductor continuity, voltage drop, and source-panel requirements.
No. Multiple feeds should not be presented as casually paralleling one continuous energized run. Where multiple feed points are used, the layout should be intentionally divided into separately fed sections and coordinated with the project electrical design.
Yes. USA TrackBusway can review project drawings and help identify feed placement, feed type, conductor configuration, and related components for a complete 225A Track Busway layout.
Splitter-based layouts may use 225A feed units as part of coordinated downstream paths, separately protected sections, or multiple 225A Track Busway runs. A splitter does not increase the rating of a single 225A run. It helps organize project-level distribution where the upstream source, overcurrent protection, conductor configuration, load calculations, and project electrical design support the layout.
Yes. Dedicated Ground / DG is available as a project-specific configuration where specified and supported. In a dedicated-ground configuration, an added internal grounding conductor is bonded to the equipment-grounding path and housing/enclosure ground. This is different from Isolated Ground / IG, where the insulated grounding path is maintained separately through compatible components and field wiring.
Isolated-ground receptacle options are available when specified on supported factory-assembled tap-off configurations. USA TrackBusway does not sell loose standalone receptacles.
200% neutral, also searched as 200 percent neutral, is available only as a project-specific 225A / T225 conductor configuration where supported. It must be coordinated with drawings, load calculations, voltage system, and electrical engineer requirements.
200% Neutral + Isolated Ground can be specified as N2IG where supported by the selected 225A / T225 configuration. Coordinate busway lengths, feed units, tap-off units, drawings, and electrical design before ordering.
