Southwire Tray Cable (TC-ER) 6/4-W/G THHN 600V

Southwire Tray Cable (TC-ER) 6/4-W/G THHN 600V

The Southwire 55343899 Tray Cable (TC-ER) 6/4 with Ground THHN 600V is a heavy-duty power and control cable built for demanding electrical installations in industrial, agricultural, and commercial environments. Designed for tray-rated exposed runs (TC-ER), this cable can be installed in cable trays, conduits, ducts, troughs, aerial messenger-supported runs, or direct burial applications. With four 6 AWG stranded copper conductors plus ground, THHN insulation, and a durable outer jacket, it provides dependable power delivery while handling harsh conditions. It’s rated for 75°C in wet locations and 90°C in dry locations, with emergency and short-circuit temperature tolerance built in—because good wiring should power the equipment, not cause the emergency.
