3-Pole T225 Tap-Off Units
All three phase conductors supply three-phase equipment. Include neutral when the equipment connection requires it.
Three phases + neutral. Select the connection you need.
The standard T225 busway shown is a three-phase, four-wire system: L1, L2, L3 and neutral (N). Its grounded housing provides the separate equipment-grounding path.
The tap-off fitting connects the conductors needed for the unit’s circuit. The supply voltage and selected conductors determine the available voltage; the tap-off does not change voltage.
Fits T225 busway only. Match the unit’s ratings to your supply and load.

Drop cord · down to the equipment
Bring the receptacle closer to the equipment with a factory-configured cord drop.

These tap-offs fit T225 busway. The system rating is up to 225A per phase, per feed; each tap-off has its own marked voltage, current and protection rating.
The tap-off uses L1, L2 and L3. The T225 3-pole outlet-box guide includes L15 and L16 connections without neutral, and L21 and L22 connections with neutral. Ground is provided separately.
Supply examples
- 208V three-phase from a 208Y/120V supply
- 480V three-phase from a 480Y/277V supply
For a 415Y/240V three-phase supply, request a matching rated T225 assembly. Three-phase equipment requires a three-phase supply; a 120/240V single-phase panel does not provide three-phase power.
T225 tap-offs are factory wired and have no field-wiring terminals. Use the selected unit’s drawings and instructions for the actual connection.
The outlet-box guide covers its listed receptacle configurations. For a drop cord, use the technical documents for the selected drop-cord assembly.

The standard assembly carries three phases and neutral. The grounded housing provides the equipment-grounding path.
