This heavy-duty 4 AWG 3-conductor Copper VNTC tray cable delivers reliable 600V power across industrial cable trays, commercial wireways, and direct-buried facility feeders. Engineered with Class B stranded bare copper phase conductors and dual-layer THHN/THWN-2 insulation, it includes a dedicated 8 AWG bare copper equipment ground wire in a compact, balanced assembly. Protected by a sunlight-, oil-, and moisture-resistant black Polyvinyl Chloride (PVC) outer jacket, it provides contractors with a versatile wiring solution rated for up to 85 Amps (75°C terminals) / 95 Amps (90°C rating) power distribution.
Routing high-amperage machinery circuits or primary branch lines requires wiring that balances physical flexibility with extreme environmental defense. Type TC/TC-ER 4 AWG 3-conductor copper tray cable slashes field labor by eliminating the need to pull individual conductors through continuous metal conduit in industrial environments. It is fully code-approved for open-air ladder trays, underground duct banks, outdoor direct burial, and hazardous chemical or utility environments.
Exposed Run Certified (TC-ER): Approved for open-air runs between cable trays and machinery or equipment disconnects per NEC Article 336, cutting installation hardware and labor costs.
3-Conductor Assembly with Ground: Features 3 black phase conductors marked with ICEA Method 4 identification ("1-One", "2-Two", "3-Three") alongside a dedicated 8 AWG bare copper ground wire.
THHN / THWN-2 Insulation: High-dielectric PVC with a tough nylon outer skin that protects against oils, chemicals, moisture, and pulling friction.
Rugged Environmental PVC Jacket: Thick black outer sheath forms a durable shield against UV sunlight exposure, direct burial earth pressures, and flame migration.

4 AWG 3-Conductor Copper Tray Cable (Type TC/TC-ER) is engineered for primary feeder power distribution, motor branch circuits, control networks, and direct-buried commercial or industrial facility feeders. It contains three 4 AWG insulated copper phase conductors and an 8 AWG bare copper equipment ground wire, making it ideal for 3-phase 3-wire power applications or single-phase 240V industrial loads without a neutral conductor.
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 tests, permitting them to be installed as exposed wiring outside of cable trays (between the tray and equipment disconnects) without requiring metal armor or continuous conduit.
Yes, absolutely. This cable is UL-listed for Direct Burial. Its heavy PVC outer jacket forms an impermeable barrier against soil pressure, groundwater, and earth corrosion without requiring a continuous conduit sleeve.
Yes. The extruded black PVC outer jacket is explicitly UL-listed and sunlight-resistant per UL 1277 standards. It features built-in UV inhibitors that prevent jacket degradation, cracking, or color fading from long-term exposure to direct sunlight in open-air cable trays, rooftop runs, and outdoor facility raceways.
Yes. It is UL-approved for use in Class 1, Division 2 industrial hazardous locations per National Electrical Code guidelines. Its outer jacket passes the IEEE 1202 / CSA FT4 flame test and resists oils, UV sunlight, and harsh chemical exposure.
Yes. If your project specifications permit aluminum conductors for cost savings or weight reduction, view our 4/3 Aluminum Tray Cable Type TC-ER with Ground (XHHW-2 PVC) here.
