208V / 480V Three-Phase Busway Tap-Off Units

Overhead Plug-In Power Drops for 3-Phase Systems

When full 3-phase power is required, our 4-pole plug-in units deliver all three hot legs (A, B, and C) plus neutral—supporting:

-208V from a 120/208V panel
-480V from a 277/480V panel

These units are essential for higher-load applications like 3-phase motors, industrial machines, or large commercial systems.

Overhead Power Distribution

Steel Track Busway is not simply lighting track, it is a power distribution system. Because of this, Steel Track Busway is capable of delivering power to items beyond just light fixtures (such as power drops to floor fixtures, etc). This is unlike mere lighting track, which per the National Electrical Code, Article 410.151A, allows for only lighting fixtures to be used with track.
