120V Single-Phase Busway Tap-Off Units
1-Pole plug-in units provide 120V (or 277V) power by tapping one hot and a neutral from the Track Busway system. They’re ideal for general-purpose receptacles, light equipment, and flexible overhead power drops.
Use this page to browse 1-Pole outlet boxes and drop cords, and reference the wiring diagrams below to confirm compatibility with your panel and circuiting.

Delivering 120V power on demand, each 1-pole plug-in unit connects to a single hot conductor and the neutral.
Designed for simplicity, these units are quick to install, easy to reposition, and ideal for flexible branch-circuit access from overhead.
Thanks to our field-selectable phasing at the busway fitting, contractors can choose the most appropriate circuit during installation—no rewiring required.

120V Busway Tap-Off Wiring Diagram
This diagram illustrates a Track Busway tap-off supplying 120V line-to-neutral power.
120V configurations are typically used for general-purpose receptacles, lighting circuits, and low-power equipment where flexible overhead access and simple circuit switching are required.
This collection includes 120V 1-Pole Track Busway plug-in products such as receptacle-in-fitters, outlet boxes, and PowerDrop cords designed for flexible overhead branch-circuit power.

Pole count refers to the internal breaker configuration of the plug-in unit, not the physical track.
1-Pole tap-offs connect one hot and the neutral to deliver 120V (line-to-neutral)
2-Pole tap-offs connect two hots (no neutral) to deliver 208V single-phase or 240V (line-to-line)
3-Pole tap-offs engage all three hots and the neutral to support 208V or 480V three-phase, four-wire configurations
For example, a 3-pole plug-in may be installed on a four-conductor (3-phase, L-L-L-N) Track Busway to serve three-phase loads with a neutral present.
Overhead Power Distribution
Track Busway is not simply lighting track, it is a power distribution system. Because of this, 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.
