What Is a Track Busway ROW?

ROW kits are straight runs of USA TrackBusway
designed to bring plug-in power directly over work areas. Each ROW combines pre-wired lengths, feeds, and PowerDrops so you can suspend single- or three-phase power exactly where you need it — without building a full grid.

Overhead Busway ROWs

Track Busway ROWs are built from pre-wired lengths that can be joined together to extend the run wherever power is needed.

Each length arrives factory-sealed, and circuitry continues by inserting a joiner between adjoining lengths. If a run should stop electrically, it can dead-end at that point. If new circuitry is needed farther down the ROW, a new feed can be added to start a separate powered section.

This modular approach allows overhead power distribution to expand, stop, or restart exactly where needed without redesigning the entire system.

BusBar Configurations

The busbar conductor layout determines the voltages available along the ROW.
Single-phase ROWs use three conductors (L-L-N) for 120V and 208Y systems.
Three-phase ROWs use four conductors (L-L-L-N) for 208/480V distribution.

Build Overhead Runs for Accessible Power

Designed for Real Work. Built-In Flexibility. Power Within Reach.

Factory-Sealed Lengths.

Every USA TrackBusway® length arrives with a factory-installed endblock that electrically seals that specific segment within the run.

Joiner Lengths or Feed Lengths.

To carry power forward, simply add a joiner insert that bridges the endblocks of adjoining lengths. Or start new circuitry using a feed length.

Extend Circuitry or Start Fresh.

This design gives you full control — extend circuits where needed or keep runs electrically isolated, all with built-in flexibility.

3-Pole Plug-In Busway Fitting

Our electrical busway system allows tap-off units to deliver specific voltages based on the pin configuration of the plug-in fitting. Each fitting connects into the busway track and determines voltage by how it taps into the conductors — available with 1-pole, 2-pole, or 3-pole breakers.

Not sure what Double-Deck means?

Single-Deck ROWs use one busway level to deliver power along the run.

Double-Deck configurations stack two busway levels, allowing additional circuits or separation of power and data.

Both configurations support single-phase and three-phase applications depending on system design.

Single-Phase Busway

1-Pole or 2-Pole Power

In three-phase buildings, you can feed the Single-Deck Track Busway with any two phases — such as A–B or B–C — to help balance loads across the system.

From USA TrackBusway®, 1-pole plug-in units use flip fittings to select which hot conductor to tap, allowing you to fine-tune phase usage without rewiring. It’s a simple, scalable way to distribute 120V loads evenly throughout the space.

For equipment that requires line-to-line power, 2-pole units are also supported.

Double-Deck Busway

Our three-phase Track Busway includes three hot conductors and a neutral, enabling both four-wire three-phase power and standard single-phase power from the same system.

1-Pole (Line to Neutral)

2-Pole (Line to Line)

Tap-Off Boxes I Customizable Plug-In Units

Plug-in tap-off units connect directly into Track Busway to deliver power where it’s needed along the run. These customizable units provide protected branch circuits and flexible access to overhead power without rewiring.
