Product Details

The ultimate solution for high-capacity 3-phase power or complex multi-circuit control, this 10 AWG 4-conductor SJOOW cord represents the peak of the "Junior" service portable cord family. Engineered to handle massive current draws in the most punishing industrial environments, this 300V-rated cord provides the electrical muscle and physical durability required for heavy automated machinery, high-wattage mobile equipment, and temporary power distribution.

Why Choose 10/4 SJOOW Flexible Cord?

The 10 AWG gauge is the largest size available in SJOOW construction, offering a high-amperage capacity that bridges the gap between standard portable tools and heavy industrial plant equipment. The SJOOW designation ensures the cord is fully resistant to Oil, Water, and Weather (UV). Its thermoset CPE jacket is chemically cross-linked, meaning it will not melt, "cold flow," or deform even under intense mechanical pressure or when in contact with high-heat surfaces.

  • 3-Phase and High-Load Versatility: The 4-conductor configuration is the industry standard for 3-phase portable motors (using the fourth wire as ground) or for heavy-duty 240V equipment requiring a neutral and a ground.

  • Elite Environmental Shielding: The Chlorinated Polyethylene (CPE) jacket provides the highest level of protection against tearing, abrasion, and degradation from cutting oils, lubricants, and industrial chemicals.

  • Extreme Cold-Weather Reliability: Rated for a temperature range of -40°C to +90°C, this cord remains supple and resistant to cracking in freezing temperatures while handling high-ambient heat without softening.

  • Industrial-Grade Mechanical Strength: Features high-count Class K bare copper stranding, providing the flexibility and durability needed for equipment that undergoes constant vibration or repetitive movement.

This 10 AWG, 4-conductor portable cord is the most robust cable in the "Junior" service class. It is engineered for applications that require massive power delivery alongside multiple control or neutral pathways. It is the specific choice for 3-phase motors, heavy-duty industrial pendants, and commercial kitchen equipment (such as large ovens or fryers) that require a 120/240V split-phase connection with a dedicated neutral and ground. With a 25-amp capacity per conductor, it handles high-torque startups and continuous heavy loads without breaking a sweat.

The SJOOW rating defines a cord built to endure high-stress environments where failure is not an option.

  • Thermoset CPE Jacket: Unlike standard PVC (thermoplastic) cords that melt or deform when exposed to heat, this rubber-like jacket is "thermoset." It maintains its structural integrity even if it accidentally brushes against a hot motor, steam pipe, or weld spatter.
  • Junior Service (J): The "J" rating denotes a 300V capacity. This allows the cord to remain more flexible and have a smaller outer diameter than its 600V "SOOW" counterparts, which is critical for wiring handheld control stations or mobile machinery where maneuverability is a priority.
  • OOW (Oil & Water Resistance): The "OO" confirms that both the internal conductor insulation and the outer jacket are resistant to oil, while the "W" ensures it is UL-listed for outdoor moisture and sunlight exposure.

Because 10-gauge copper is thick and heavy, it would be virtually impossible to bend if it were solid. 10/4 SJOOW solves this by using Class K high-strand-count bare copper.

  • Repeated Flexing: Hundreds of fine copper wires are twisted together, allowing the thick cord to bend, twist, and be coiled thousands of times without the metal "work-hardening" or snapping.
  • Vibration Resistance: In manufacturing environments, machines create constant micro-vibrations. This stranded construction prevents the wires from fatiguing at the terminal blocks, ensuring a secure and low-resistance connection for years.
  • Cold-Weather Suppleness: The combination of stranded copper and the CPE jacket allows the cord to remain easy to handle and unroll in temperatures as low as -40°C.

To prevent dangerous wiring errors in multi-phase or complex control setups, this cord follows the standard North American color code:

  1. Black: Hot (Phase 1)
  2. White: Neutral (or Phase 2)
  3. Red: Secondary Hot (or Phase 3)
  4. Green: Ground
    This 4-wire configuration allows for 3-phase power plus ground or 240V equipment with a neutral, meeting all NEC and OSHA safety requirements for equipment grounding.

This cord is built to perform in the harshest "real-world" industrial climates:

  • Thermal Range: Rated for continuous operation between -40°C and 90°C.
  • Chemical Immunity: The jacket is specifically formulated to resist degradation from gasoline, diesel, machine oils, solvents, and acids.
  • Abrasion Resistance: The thick thermoset jacket is designed to be dragged over concrete and rough factory floors without tearing or exposing the internal conductors.
