40A Track Busway Feed Units

Single-phase line feed

Single-phase Track Busway with feed unit and flex conduit connection for overhead power supply

40A Track Busway feed units bring panel power into a USA TrackBusway run. Choose starter, junction, line, single-phase, or three-phase feed options to introduce power at the point that best fits the layout.

In a 40A Track Busway system, the feed does not have to be thought of as only a fixed end-of-run accessory. Feed placement can be coordinated around workstations, benches, lighting zones, tools, modular rows, bridges, or smaller equipment areas.

The feed introduces power into the busway system, while the Track Busway run distributes that power overhead so compatible plug-in tap-offs can be positioned where power is needed.

Place Power Where the 40A Layout Needs It

USA TrackBusway feed placement can be coordinated around the actual layout instead of forcing every project into one fixed power-entry strategy. For smaller 40A Track Busway run layouts, this can be useful when the system supports workstations, benches, lighting, tools, retail fixtures, modular rows, or smaller equipment zones.

A feed may be located where it best supports the layout, while compatible 40A tap-offs can be positioned farther along the busway where power is needed. Final feed placement should still be coordinated with the project drawings, upstream overcurrent protection, conductor configuration, voltage drop, access, and code requirements.

This does not mean feeds should be added casually or without electrical coordination. For help selecting the correct feed type, phase, voltage, and protection method, request a layout review before finalizing the 40A system.

40A Feed Units for Track Busway Power Entry

40A feed units connect incoming electrical service to a USA TrackBusway run. These products are used where power needs to enter the 40A system, whether at the end of a run, through a junction feed, or along the run with a line feed.

Unlike conventional pipe-and-wire layouts, where power entry and downstream power access are often tied to fixed conduit and junction-box locations, USA TrackBusway separates power entry from plug-in power access. The feed brings power into the run, while the open-slot busway allows compatible tap-offs, outlet boxes, and drop cords to be positioned farther along the layout.

This helps simplify layout changes, reduce field wiring compared with conduit-only layouts, and support future expansion when work areas or power needs change.

Simple Install Instructions

Installing single-phase 40A Track Busway feed and run for overhead power distribution

Choose a 40A Feed Type

40A Track Busway feeds are available in several configurations depending on where power enters the run and how overcurrent protection is handled.

Starter FEEDs provide a compact power-entry point for simple end-fed or center-fed layouts.
Junction FEEDs provide a non-breakered feed option when overcurrent protection is handled upstream.
Line FEEDs include integrated breakers and can introduce protected power along the run where the layout requires it.
Three-phase line feeds support 40A three-phase Track Busway layouts when the project requires 3-phase power distribution.

Select the feed type that matches the source panel, protection strategy, voltage, phase, and layout requirements.

Choose Your Feed Wiring Configuration

Use the options below to review typical single-phase and three-phase 40A Track Busway feed configurations. These diagrams help illustrate how power is introduced into the busway run so downstream plug-in devices can access power along the layout.

Note: Final feed placement should be coordinated with the project drawings, panel location, voltage, phase, overcurrent protection, and conductor continuity requirements.

Build Your Track Busway System

Continue building your 40A Track Busway system by selecting the core system components. RUNs define the overhead power path, FEEDs introduce power into the system, and TAP-OFFs deliver power where it is needed along the run.
