Electrical & Automotive Primary Wire

Del City is your direct connection for all electrical and automotive wiring needs. We offer a huge selection of primary wire from 20 to 8 gauge sizes, in a variety of colors and spool lengths to fit the exact demands of your project or application. The single conductor primary wire features a polyvinyl chloride (PVC) insulation that is highly durable and resistant to grease, oil, and acids - making it ideal for automotive, truck, trailer, marine, construction, and many other electrical connections. Del City's primary wire is manufactured to meet or exceed SAE specifications J1128 and operates optimally between temperatures -40°C to 80°C (-40°F to 176°F).

The gauge size of the primary wire offered refers to the outer diameter of the copper strands housed within the PVC insulation, not including the insulation walls. The thickness of the insulation may vary slightly, but the gauge size within will not. The wire below ranges from 20 gauge (nominal O.D. = .084 inches) to 8 gauge (nominal O.D. = .208 inches) and is offered in 100 feet to 6,000 feet spools, as well as convenient thrifty spools in select gauge sizes. An assortment of wire colors is available, depending on gauge and spool length, including: red, white, blue, green, black, yellow, brown, grey, purple, and orange. Whether you are working on a large project, a set of applications, or just making a quick repair - Del City has you covered. Find just the right gauge, color, and spool size of primary wire you need, in stock and ready to ship.
