2-Pole T225 Tap-Off Units
Two phase conductors supply a single-phase, line-to-line load. Neutral depends on the equipment connection.
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.
Select the phase pair: L1–L2, L2–L3 or L1–L3. The T225 2-pole outlet-box guide includes L6 and L8 connections without neutral, and L14 connections with neutral. Match the receptacle and selected build.
Supply examples
- 208V from a 208Y/120V supply
- 480V from a 480Y/277V supply
For 120/240V or 415Y/240V projects, request a matching rated T225 assembly. Supply voltage alone does not establish product compatibility.
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.
Model-based cutaway; supply routing is schematic. IG and 200% neutral configurations differ.
