Southwire Tray Cable (TC) 8/4-W/G THHN/PVC

Southwire Tray Cable (TC) 8/4-W/G THHN/PVC

The 55769499 Southwire Tray Cable (TC) 8/4 with Ground THHN/PVC is a heavy-duty 600-volt power and control cable designed for demanding industrial and commercial installations. Built with four 8 AWG stranded copper conductors plus ground, this tray cable is engineered for excellent electrical performance and long-term durability in both indoor and outdoor environments. Rated for wet and dry locations, it can be installed in cable trays, conduit, ducts, troughs, or direct burial, and may also be used in aerial applications when supported by a messenger. With TC-ER exposed-run approval and hazardous location compatibility, this cable is a reliable choice for serious electrical work—essentially the electrical equivalent of “install it once and forget about it.”
