Southwire 55669123 14 Gauge Automotive Primary Wire 100 Ft

Product Description

The SOUTHWIRE 55669123 is a 14 gauge automotive primary wire rated for use in surface vehicle electrical systems. This 100-foot spool is insulated with PVC and colored red for easy circuit identification. The wire features a 19/27 strand configuration for flexibility during routing through vehicle harnesses, panels, and chassis components. Rated at 60 volts and up to 85 degrees F, it meets SAE standards for automotive wiring applications. The outside diameter measures 0.12 inches (3.05 mm). Automotive electricians, fleet technicians, and specialty vehicle builders use this wire for primary circuit runs, accessory wiring, and system repairs where a flexible, color-coded conductor is required.

This wire is suited for 12-volt and 24-volt surface vehicle electrical systems including passenger cars, light trucks, trailers, and specialty vehicles. The red insulation supports color-coded wiring practices, making it easier to trace circuits and document harness layouts during installation or service. The 100-foot spool length accommodates both single-run jobs and multi-circuit installations without requiring additional splicing. It is appropriate for low-voltage primary circuits in automotive, marine-adjacent, and off-road vehicle applications where SAE-compliant wire is specified.

Installation Notes

Installation should be performed by a qualified automotive or fleet electrician familiar with vehicle wiring practices. Disconnect the vehicle battery before beginning any primary circuit work to prevent shorts or unintended activation of electrical components. Route wire away from sharp edges, heat sources, and moving parts, and secure with appropriate grommets, clips, or conduit. Follow all applicable SAE and vehicle manufacturer wiring guidelines when sizing circuits and selecting overcurrent protection.
