Part of the 40A Track Busway System

This breakered line feed connects the facility supply to a compatible 40A Track Busway run. Build the supply path with 40A track busway lengths and the appropriate power feed.

Match the feed's breaker rating and the busway configuration to the facility supply. Connect compatible power drops and outlet boxes along the run. Use the Track Busway system design guide to plan the complete layout.

Simplify Overhead Power

Track Busway transforms open ceiling spaces with an innovative system that eliminates traditional overhead power structures, simplifying installations while maximizing flexibility.

Pre-Wired Power Infrastructure: Deliver branch-circuit power exactly where it’s needed using pre-wired Track Busway lengths. Power drops can be added, moved, or reconfigured without rewiring to support evolving layouts.

Plug-and-Play Power Access: Tool-free, plug-in power taps with multiple receptacle options provide fast, reliable access to overhead power while maintaining code-compliant distribution.
