10/3 SJOOW Flexible Cord | 300V

The heavy-duty standard for grounded portable power, this 10 AWG 3-conductor SJOOW cord is designed for maximum power delivery in rigorous industrial environments. Featuring high-capacity copper conductors and a specialized thermoset jacket, this 300V-rated cord provides the electrical muscle and physical resilience required for the most demanding professional tools, high-wattage machinery, and temporary power applications.

Why Choose 10/3 SJOOW Flexible Cord?

The 10 AWG conductors offer a massive 30-amp capacity, making this the primary choice for equipment where 12 AWG would result in excessive voltage drop or overheating. The SJOOW designation identifies it as a “Junior” (300V) service cord that is fully resistant to Oil, Water, and Weather (UV). Its thermoset CPE jacket is chemically cross-linked, ensuring it will not melt, “cold flow,” or deform even under intense heat or mechanical pressure.

• Maximum Power Throughput: Optimized for 30A grounded circuits, providing the necessary current for high-torque motors and heavy industrial heating systems.

• Elite Environmental Shielding: The Chlorinated Polyethylene (CPE) jacket is engineered to withstand constant exposure to cutting oils, lubricants, and harsh solvents without degrading or swelling.

• Sub-Zero Resilience: Rated to remain supple and maneuverable in temperatures as low as -40C, preventing the jacket brittleness and cracking that plagues thermoplastic cords in winter conditions.

• Safety Ground Integration: Includes a dedicated green grounding conductor along with standard black and white leads, providing essential fault protection for metal-housed tools.

• Superior Flex Life: Features high-count Class K bare copper stranding, allowing the cord to endure constant coiling, vibration, and pulling without conductor fatigue.
