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 -40C to +90C, 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.
