USA TrackBusway® Three-Phase Lengths deliver scalable, overhead plug-in power for multi-circuit and high-load environments. Each steel housing is pre-wired with three hot copper conductors, one neutral + an optional isolated ground, and factory sealed with end caps to form a self-contained grounded section ready for installation. Power may continue through abutting sections using USA TrackBusway® Joiner Inserts, or additional feeds can be added anywhere using a USA TrackBusway® Line Feedwith integral overcurrent protection. The continuous access slot accepts plug-in power taps like Power Drop Cords or Outlet Boxes anywhere along the run—no rewiring or downtime required. Available in galvanized, white, or black finishes, and in lengths of 2.5', 3', 5', 7', and 10'. If three-phase power drops are not required, you may want to explore single-deck lengths for 120/208Y single-phase power distribution.
