Southwire 55879923 10 Gauge Automotive Primary Wire 100 Ft

Product Description

The SOUTHWIRE 55879923 is a 10 gauge automotive primary wire designed for use in surface vehicle electrical systems. This 100-foot spool features blue PVC outer insulation and a 19-strand conductor configuration, providing flexibility and reliable conductivity in demanding vehicle wiring applications. Rated for 60 volts and a maximum operating temperature of 85 degrees F, it meets SAE standards for automotive primary wire. The blue color coding simplifies circuit identification during installation and troubleshooting. Licensed automotive electricians and 12-volt specialists routinely use this wire for power distribution, accessory wiring, and chassis harness work.

This wire is suited for use in passenger vehicles, light trucks, trailers, marine craft, and other surface vehicle electrical systems where a flexible, color-coded primary wire is required. The 100-foot spool length accommodates both single-run installations and multi-run jobs on a single vehicle. Its PVC jacket resists abrasion and common automotive fluids, making it appropriate for routed and loom-protected wiring in engine compartments, interior panels, and underbody applications.

Installation Notes

Installation should be performed by a qualified 12-volt technician or automotive electrician familiar with vehicle wiring practices. Disconnect the vehicle battery before beginning any wiring work to eliminate shock and short-circuit risk. Route wire away from sharp edges, exhaust components, and moving parts, using grommets and loom protection as required. Follow SAE wiring practices and any applicable vehicle manufacturer specifications for termination and connector type.
