Track Busway Outlet Boxes

Compare plug-in outlet boxes for T40 and T225 Track Busway. A multi-circuit busway distributes power on up to three phases. Each tap-off connects to the phase conductor(s), and neutral when needed, for its load.

Tap-offs select a circuit; they do not convert voltage. Match the supply, tap-off and equipment ratings.

T40 and T225 are not interchangeable. The system rating is separate from each tap-off’s load rating.

Why use Track Busway outlet boxes?

Keep receptacle access directly at the overhead busway so equipment cords can plug in at track level.

Explore breakered outlet-box tap-offs for protection at the connection. Unbreakered alternatives are also available where the circuit design calls for them. For power needed lower in the space, use a drop cord.

1-Pole Outlet Boxes (line-to-neutral)

One phase conductor + neutral supplies a single-phase load:

  • 120V from a 120/240V or 208Y/120V supply
  • 277V from a 480Y/277V supply
  • 240V from a 415Y/240V supply

The T40 products shown below are 120V models; other voltages require a matching rated build.

When should I choose a 1-pole outlet box?

Choose a line-to-neutral outlet-box tap-off when single-phase equipment can plug in at the busway. A breakered outlet box provides protection at the tap-off. Match the receptacle, voltage and breaker rating to the load, and the fitting to T40 or T225.

Need power that retracts when the work is done?

A breakered cord reel brings 120V power within reach, then returns the cord overhead when it is not in use.

Busway support requires threaded rod larger than 1/4 in. nominal diameter. 1/4-20 rod is not permitted. Choose the reel that matches your busway family. All receptacles on each reel share one 120V, 20A branch.

2-Pole Outlet Boxes (line-to-line)

Two hot conductors supply a single-phase load:

  • 240V from a 120/240V single-phase supply
  • 208V from a 208Y/120V three-phase supply
  • 480V from a 480Y/277V three-phase supply
  • 415V from a 415Y/240V three-phase supply

Select a tap-off rated for the line-to-line voltage; 480V and 415V require a matching rated build.

How do I choose a 2-pole breakered outlet box?

Match the equipment’s line-to-line voltage, receptacle and required current to the selected tap-off. Keep the outlet at the busway when the equipment cord can reach it; use a drop cord when receptacle access is needed lower down.

3-Pole Outlet Boxes (three-phase)

All three phase conductors serve a three-phase load. Supply examples:

  • 208Y/120V
  • 480Y/277V
  • 415Y/240V

Match the selected tap-off’s voltage rating and neutral connection to the equipment; 415Y/240V T225 builds are project-specific.

Does a 3-pole outlet box need a neutral?

That depends on the equipment connection. Three phase conductors serve the three-phase load; neutral is included when required by the selected receptacle and assembly. Confirm the wiring and protection for the exact T40 or T225 outlet-box tap-off.
