A heavy-duty 600V/1000V dual-rated 500 kcmil 4-conductor aluminum tray cable engineered for power, control, signal, lighting, and branch circuit distribution in commercial, industrial, and utility environments. Constructed with Class B compact stranded 8000 series aluminum alloy conductors wrapped in flame-retardant XHHW-2 insulation, this cable is protected by a heavy-duty, sunlight- and moisture-resistant black Polyvinyl Chloride (PVC) outer jacket. Featuring an Exposed Run (TC-ER-JP) rating, it can transition directly from cable trays to equipment or conduit without requiring metal armor or continuous conduit enclosures per NEC Article 336.
When routing multi-conductor power lines across commercial facilities, industrial plants, or outdoor sites, installation flexibility and physical durability are critical. Type TC-ER 500 kcmil 4-conductor aluminum cable eliminates the high cost and labor of pulling individual conductors through rigid conduit. It is approved for direct earth burial, aerial messenger wire support, outdoor tray runs, and wet/dry industrial environments exposed to oils, chemicals, and sunlight.
Exposed Run Certified (TC-ER-JP): Listed for exposed runs between cable trays and utilization equipment or raceways per NEC Article 336, drastically reducing installation labor and conduit hardware costs.
4-Conductor Assembly with Ground: Contains 4 black insulated circuit conductors (typically 3 phases + 1 neutral) with ICEA Method 4 printed numbers ("1-One", "2-Two", "3-Three", "4-Four") plus 1 dedicated green insulated 1 AWG aluminum ground wire.
XHHW-2 Core Insulation: Individual conductors feature heat- and moisture-resistant cross-linked polyethylene (XHHW-2) insulation rated for 90°C wet or dry locations.
Industrial PVC Jacket: Tough black PVC outer sheath resists sunlight (UV), moisture, flame, petroleum oils (PRI/PRII), and direct burial earth pressure.

500 MCM 4-Conductor Aluminum Tray Cable (Type TC-ER) building wire is designed for high-capacity primary power distribution, main service feeders, control networks, and heavy machinery circuits in commercial and industrial settings. It contains three 500 kcmil circuit conductors and a 1 AWG ground wire, making it ideal for 3-phase 3-wire power applications or high-amperage single-phase loads without neutral.
TC-ER stands for Tray Cable - Exposed Run under UL 1277 standards. Under NEC Article 336, cables carrying this rating pass rigorous crush and impact testing, permitting them to be installed as exposed wiring outside of cable trays without requiring metal armor or conduit.
Yes, absolutely. This cable is UL-listed for Direct Burial. Its heavy PVC outer jacket and XHHW-2 insulated conductors protect the assembly against soil moisture, earth pressure, and direct chemical exposure without requiring a conduit sleeve.
A 500 kcmil 3-Conductor Tray Cable contains 3 circuit conductors plus a ground (used for 3-phase 3-wire systems or single-phase loads without neutral). A 500 kcmil 4-Conductor Tray Cable contains 4 circuit conductors plus a ground, accommodating 3-phase 4-wire systems that require a dedicated neutral conductor (such as 120/208V or 277/480V circuits).
Yes. It is UL approved for use in Class 1 and Class 2, Division 2 industrial hazardous locations per National Electrical Code standards. Its outer jacket passes the rigorous IEEE 1202/FT4 flame test and is resistant to gas and oils (PRI/PRII).
Yes. When terminating 8000 series aluminum conductors, always wire-brush the bare strands, apply a listed antioxidant joint compound (de-ox) to prevent oxidation, and tighten terminal lugs to the manufacturer's specified torque rating using AL7CU or AL9CU dual-rated connectors.
Yes. If your equipment disconnects require copper conductors, or if you require higher ampacity in a compact footprint, view our 500 MCM 4-Conductor Copper Tray Cable Type TC-ER (THHN/PVC).
