Southwire 55671823 10 Gauge Automotive Primary Wire 100 Ft

Product Description

The SOUTHWIRE 55671823 is a 10-gauge black automotive primary wire designed for surface vehicle electrical systems. Measuring 100 feet in length, it features a PVC outer insulation rated for temperatures up to 85 degrees F and a 19/23 strand count that provides flexibility for routing through tight chassis and body cavities. The outside diameter measures 0.178 inches. This wire is packaged on a spool for clean, organized dispensing and is sized for general-purpose 12-volt automotive and fleet wiring applications. Automotive electricians, fleet maintenance technicians, and experienced DIYers install this type of wire for primary circuit runs, accessory feeds, and trailer wiring harnesses.

This wire is suited for surface vehicle electrical installations where a flexible, insulated primary conductor is required. Common applications include power feeds to accessories, lighting circuits, audio systems, trailer connectors, and general chassis wiring. The 100-foot spool length accommodates multiple circuits or full-vehicle harness runs from a single package. The black color supports standard color-coding practices used in automotive wiring.

Installation Notes

Installation is typically performed by automotive electricians or fleet maintenance technicians familiar with SAE and vehicle wiring standards. Disconnect the vehicle battery before beginning any primary circuit work. Use appropriate crimp terminals, wire looms, and grommets when routing through firewalls or sharp edges. Verify ampacity requirements for the intended circuit load before selecting wire gauge.
