The 18 AWG 3-conductor SJOOW cord is a highly resilient, flexible solution for portable power and grounding. Engineered to handle the rigors of industrial environments, this 300V-rated cord features high-flex stranding and a specialized thermoset jacket that provides ultimate protection against oils, chemicals, and extreme weather.
The SJOOW designation is the industry hallmark for durability in "Junior" (300V) service. With three conductors, this cord is the standard choice for portable equipment requiring a dedicated equipment ground. The thermoset jacket is "cured" during manufacturing, meaning it will not melt or deform even when in direct contact with high-heat surfaces or hot oils.
Superior Environmental Shielding: The CPE (Chlorinated Polyethylene) jacket is rated for continuous exposure to oil, water, and sunlight (UV), making it suitable for both indoor and outdoor industrial use.
Cold-Weather Flexibility: Remains supple and easy to coil in temperatures as low as -40°C, preventing the jacket brittleness and cracking common in standard PVC cords.
High-Flex Stranding: Features Class K bare copper stranding, specifically designed to withstand the mechanical stress of constant coiling, pulling, and vibration.
Safety Ground Integration: Includes standard color-coded conductors (Black, White, Green) to ensure safe and proper grounding of portable hand tools and machinery.
Conductor Size: 18 AWG
Number of Conductors: 3
Color Code: Black, White, Green
Ampacity: 10 Amps (Based on NEC Table 400.5(A)(1))
Voltage Rating: 300V
Jacket Material: Premium Grade Thermoset CPE (Black)
Insulation: Oil-Resistant EPDM
Conductor Material: Fully Annealed Stranded Bare Copper (Class K)
Standards: UL 62, CSA C22.2 No. 49, MSHA Approved, OSHA Acceptable
Portable Hand Tools: The definitive choice for grinders, soldering stations, and specialized industrial drills.
Temporary Job-Site Lighting: Reliable power delivery for LED work lights and temporary construction area illumination.
Industrial Pendant Controls: Ideal for overhead crane controls and push-button stations where high flexibility is required.
Commercial Floor Care: Frequently used for professional vacuum cleaners and floor buffers that face constant movement and abrasion.
Small Motor Leads: Perfectly suited for powering small pumps, fans, and blowers in environments where oil or water splashes are likely.
Extension Cord Fabrication: The industry standard for creating heavy-duty custom-length extension cords for professional use.
Technical Note: All values are nominal and subject to industry tolerances and manufacturer corrections. Specifications are subject to change without notice. It is the buyer’s responsibility to verify that all materials meet the specific requirements of the project and comply with local electrical codes.

This 18 AWG, 3-conductor portable cord is the standard choice for grounding-type light-duty electrical equipment. It is most frequently used for powering portable tools, small appliances, and shop lights, as well as for OEM power supply cords on consumer electronics. Because it includes a dedicated grounding conductor, it is the safe choice for any equipment with a metal housing that requires protection against electrical shock.
The SJOOW label identifies the cord's specific construction and environmental durability:
This cord is rated for 10 Amps per conductor. This rating is based on an ambient temperature of 30°C (86°F) per NEC standards for 3-conductor assemblies.
Yes. The "W" rating indicates the cord is water and weather-resistant, meaning it is designed to hold up against rain, sunlight, and outdoor temperature fluctuations.
Following the standard North American color code for 120V power, the three conductors are identified as:
18/3 SJOOW is designed for "Hard Service," meaning it can survive conditions that would destroy standard plastic extension cords:
Standard extension cords (often made with PVC or SJT jackets) stiffen in the cold and melt when exposed to oils or heat. SJOOW uses rubber-based materials that maintain their flexibility and chemical resistance, making them the only choice for professional/industrial use.
