How Tap-Off Units Connect to 40A Busway

40A Track Busway tap-off units plug into the busway channel to deliver power from the overhead run to the point of use. Use Outlet Boxes when receptacles should stay mounted directly at the busway for fixed overhead access. Use Power Drop cords when receptacles need to hang closer to equipment, benches, workstations, or production areas.

Browse the related tap-off collections below to choose between Outlet Boxes and Power Drop cords, or use the 40A configuration links above to select the correct 120V / 1-pole, 208V or 240V / 2-pole, or 3-phase / 3-pole plug-in family.

Multi-Voltage Track Busway – Wiring Diagram

This diagram illustrates how Track Busway distributes electrical power along an electrified busway run and allows plug-in units to connect anywhere along the system.

Three-phase Track Busway configurations are commonly used for industrial equipment, mixed circuit distribution, and applications requiring balanced three-phase power.
