Rugged Durability for Tough Conditions: Our Heavy Duty 16 AWG 300V SJOOW (Service, Oil, and Water Resistant) cable (50 FT - 4 Conductor) is the first choice for industrial, commercial, and outdoor uses. With its insulated design and robust PVC jacket, it's built to withstand oils, acids, water, and chemicals, ensuring reliability in even the harsh environments (-40 to 90). Safety and Superior Performance with OFC (Oxygen Free Copper) Wire: Our 16/4 AWG OFC (Oxygen Free Copper) wire has 4 conductors. Each conductor features 42 thin copper wire to manufacture, delivering enhanced conductivity for greater current capacity. Benefit from heightened corrosion resistance and superior heat absorption compared to non-OFC wire, ensuring reliable performance and peace of mind. SJOOW Electrical Wire Applications: This type of wire finds frequent use in industrial settings, as well as outdoor and marine environments. Each wire is made of 4 conductors, each conductor has an average thickn
