Electrical & Automotive Primary Wire

Del City: Your Trusted Source for High-Quality Electrical and Automotive Wiring Solutions

Del City provides direct access to a comprehensive range of electrical and automotive wiring products, tailored to meet the specific requirements of your projects. Our extensive selection of primary wire spans from 20 to 8 gauge sizes, available in various colors and spool lengths to ensure the perfect fit for any application. Each single conductor primary wire is encased in durable polyvinyl chloride (PVC) insulation, designed for superior resistance against grease, oil, and acids. This makes it ideal for use in automotive, truck, trailer, marine, construction, and a wide array of other electrical connections. Del City’s primary wire is engineered to meet or exceed SAE J1128 specifications, delivering optimal performance across a wide temperature range from -40°C to 80°C (-40°F to 176°F).

Our primary wire gauge sizes represent the outer diameter of the copper strands within the PVC insulation, exclusive of the insulation's thickness. While the insulation thickness may vary slightly, the integrity of the wire's gauge remains consistent. We offer wire sizes ranging from 20 gauge (nominal outer diameter = .084 inches) to 8 gauge (nominal outer diameter = .208 inches), with spools available from 100 feet to 6,000 feet. Additionally, we provide thrifty spools in select gauge sizes for added convenience. A broad spectrum of wire colors is also available depending on gauge size and spool length, including red, white, dark blue, dark green, black, yellow, brown, gray, purple, and orange. Whether tackling a large-scale project, a specific set of applications, or performing a quick repair, Del City offers the precise gauge, color, and spool size you need—always in stock and ready to ship
