Engineered for extreme durability and continuous heavy-duty power distribution, this 4 AWG 3-Conductor Type W Portable Power Cable is built to withstand relentless jobsite punishment. Rated for continuous 2000V operation, this industrial-grade trailing cable features fully flexible tinned copper conductors insulated with high-dielectric Ethylene Propylene Rubber (EPR) and encased in a heavy-duty Chlorinated Polyethylene (CPE) thermoset outer jacket.
Whether powering heavy mining machinery, mobile compressors, high-capacity temporary generators, or 3-phase motor leads, this cable delivers unyielding mechanical impact resistance, extreme cold flexibility down to -40°C, and superior defense against oil, heat, flame, and sunlight.
Extra-Flexible High-Strand Tinned Copper: Built with 259 fine strands of soft-drawn tinned copper (ASTM B33) per conductor, giving you maximum flexibility around tight corners while preventing copper oxidation and corrosion at lugs and terminations.
Ultra-Rugged Thermoset CPE Jacket: Heavy-duty Chlorinated Polyethylene (CPE) outer sheath provides extreme protection against severe mechanical impact, sharp rock abrasion, crushing, fuels, solvents, and aggressive chemicals.
Extreme Weather & UV Protection (-40°C to +90°C): Highly resistant to ozone, UV sunlight, weather, open flames (FT1/FT5), and shallow water immersion. It stays completely pliable in sub-zero freezing cold down to -40°C while delivering full 90°C wet/dry thermal protection.
2000V Heavy-Duty Power Capacity: High-grade Ethylene-Propylene Rubber (EPR) insulation delivers high dielectric strength and reliable 2000V power density without thermal breakdown.
Color-Coded Conductors: Features color-coded conductors (Black, White, Green) for fast, error-free circuit and phase identification during panel assembly and field terminations.
Anti-Slipping Core Construction: Built with rubber fillers and a heavy-duty internal binder tape that locks the inner conductors to the outer jacket. This prevents internal slippage, conductor twisting, and sleeve bunching when dragging the cable across job sites or pulling under high tension.

Multi-conductor 4/3C Type W cable is a heavy-duty 2000V portable power cable designed for high-amp three-wire temporary power distribution, dynamic portable equipment, industrial pumps, and mining equipment. Common uses include generator tails, heavy industrial motor leads, shallow water dewatering pumps, shipyard power, and temporary jobsite distribution panels.
Per NEC Table 400.5(A)(2) and manufacturer specs, a 4 AWG 3-conductor Type W cable rated at 90°C carries a maximum continuous ampacity of 130 Amps in free air (based on a 30°C ambient temperature). Always check derating factors and local electrical codes for your specific setup.
Yes. 4 AWG Type W cable features an extra-heavy-duty CPE jacket and EPR insulation rated for shallow water immersion, as well as wet or dry environments from -40°C to +90°C. It handles continuous UV sunlight, ozone, oils, and aggressive jobsite chemicals without breaking down.
No. Under NEC Article 400, multi-conductor flexible portable power cords are restricted to temporary power distribution and equipment leads. Unlike single-conductor Type W (which carries a dual RHH/RHW-2 building wire rating), multi-conductor Type W cannot be pulled through permanent building conduit or raceways.
While both are multi-conductor flexible cords, they are built for different duty levels:
4 AWG 3-Conductor Type W uses 259 fine strands of tinned copper per conductor for extra pliability around tight corners. With a minimum bending radius rating of 6 times the overall outer diameter (1.14" OD), this cable needs a minimum bending radius of 6.84 inches (174.0 mm) for safe routing.
The three conductors inside a 4/3C Type W cable are color-coded Black, White, and Green for clear circuit identification. Per UL and CSA standards, the Green conductor is designated specifically for grounding purposes.
Yes! Wire America supplies 4/3C Type W cable cut-to-length by the foot with zero cut fees, so you only pay for the exact footage your jobsite demands. Full master reels are also available for major industrial projects with fast jobsite delivery
