Three-Phase Track Busway ROWs
Three-Phase Track Busway ROWs provide overhead power distribution for 208V and 480V applications in industrial environments. These ROWs support higher-capacity loads while maintaining plug-in flexibility for changing equipment layouts.
For additional installation scenarios, configuration examples, and system overviews, visit the Track Busway Video Library →
These units tap two hot conductors to deliver line-to-line power:
-240V from a single-phase panel
-208V from a 120/208V three-phase panel
-480V from a 277/480V three-phase panel
Build a three-phase overhead run using Track Busway lengths designed for balanced power distribution in industrial and high-load environments.

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.
Three-Phase Track Busway Lengths
TWO-CIRCUIT if Single-Deck.
FOUR-CIRCUIT if Double-Decked.
USA TrackBusway® lengths feature insulated copper bus bars within a durable, U-shaped steel housing. A continuous open slot allows plug-in units to be installed anywhere along the track—providing flexible, efficient power distribution for dynamic layouts.
