Track Busway delivers plug-in overhead power distribution with flexible, open-slot accessibility. Designed for both single-phase and 3-phase systems, it provides a cost-saving alternative to conduit and trunking while supporting a wide range of plug-in units.
Plug-In Power Overhead
Plug-in power taps connect anywhere along the open-slot Track Busway, allowing drops, outlet boxes, and equipment connections to be positioned or repositioned without cutting conduit or pulling new wire. Breakered plug-in units provide protected branch circuits while maintaining full flexibility overhead.
Plug-in power drops can be configured as outlet boxes or breakered drop cords, depending on the application. Outlet boxes provide a fixed receptacle at the point of use, while breakered drop cords deliver protected branch circuits for equipment and workstations—both installing directly into the open-slot Track Busway without conduit.
For applications requiring local branch-circuit protection at the point of use, see our Breakered Outlet Box.
Open-Slot Design
Track Busway uses a continuous open-slot design with insulated copper conductors housed inside a steel channel. This allows plug-in devices to access power anywhere along the run, rather than at fixed tap-off points.
Unlike conduit or fixed-window busway, open-slot access supports faster installation, easier expansion, and fewer homerun feeds — all while remaining code-compliant under UL 857 and NEC Article 368.
Power Plug-In Categories (by Breaker Type)
Track Busway power plug-ins are organized by internal breaker configuration. Use the links below to browse available power tap-off units by pole type. 1-Pole power plug-ins, 2-Pole power plug-ins, and 3-Pole power plug-ins.
The diagrams below illustrate how each pole configuration connects conductors and delivers voltage to the load.
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
Pole count refers to the internal breaker configuration of the plug-in unit, not the physical track.
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.
Supplying Power Where You Need It
Track Busway offers suspended power distribution systems that provide reliable and safe power connections. With track busway overhead, power sockets are no longer limited to the walls or floor. You can have a well-lit area, maintain strong and consistent WiFi signals throughout, and decorate the space with zero cable clutter.
By delivering power directly overhead, Track Busway reduces floor congestion, long cord drops, and wall-mounted receptacle limitations. This makes it ideal for environments where layouts change frequently and power access must remain close to the point of use.

Overhead Power Configurations
Track Busway layouts can be designed as Rows, Grids, Rectangles, or Bridges. These modular options let designers quickly configure overhead power to fit any space
-
GRIDGRID configurations create evenly distributed overhead power across large areas. Ideal for facilities that require uniform coverage, GRIDs reduce homerun feeds and support flexible placement of power drops throughout the space.
-
RECTANGLEsRECTANGLE layouts provide structured perimeter and interior coverage for defined work zones. This configuration is commonly used where power needs to be evenly distributed around equipment, benches, or production areas.
-
ROWsROW configurations deliver linear overhead power directly above workstations or equipment lines. ROWs are ideal for targeted power distribution in manufacturing cells, labs, and retail environments.
Pre-Fabricated System
- NRTL listed to UL 857 Busway Standards.
- 120V, 208Y (Single-Phase), 208V (Three-Phase), 277V, and 480V compatible.
- Open slot accessibility for ease in re-locating / adding elements.
- Built-in code compliance with protection from fuses / breakers
- Minimize home-run feeds with 160A feeder capacity (4 x 40amp circuits)
Customizable Plug-In Units
Tailor your power drop units with a variety of plug-end options, including duplex or quad boxes, and choose between twist-lock or straight-blade receptacles. For added safety and reliability, each unit can be equipped with circuit breakers or fused disconnects, ensuring a solution perfectly designed for your requirements.
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.
Reduce Circuitry with Trunking Track Busway
Busways are modern, cost-effective tools for distributing electricity in a building. Steel track is a busway, a prefabricated electrical distribution system with insulated conductors hidden inside a steel strut housing.
Because of the nature of busways, one perpendicular row can often aggregate many branches into just one homerun feed. Individual busway sections may be double-decked in the field to achieve up to 4x40amp circuits. Feeding costs with Track Busway are drastically reduced because busway projects inherently have far fewer homerooms.
