Southwire 55671923 10 Gauge Automotive Primary Wire 100ft

Product Description

The SOUTHWIRE 55671923 is a 10 gauge automotive primary wire designed for use in surface vehicle electrical systems. Supplied on a 100-foot spool, this white PVC-insulated wire carries a 60-volt rating and is built to handle the vibration, heat, and routing demands common in automotive and light-vehicle wiring applications. The 19/23 strand configuration provides flexibility for runs through tight spaces and around bends without compromising conductivity. With an outside diameter of 0.178 inches and a maximum temperature rating of 85 degrees F, it fits standard automotive wiring connectors and terminals. Licensed electricians and automotive technicians install this wire for accessory circuits, trailer wiring, and other low-voltage vehicle electrical work.

This primary wire is suited for 12-volt and low-voltage DC circuits in cars, trucks, trailers, and other surface vehicles. The white color coding supports organized, readable wiring harnesses where circuit identification matters. The 100-foot spool length covers most single-circuit runs or provides stock for multiple shorter runs on a service vehicle or in a shop environment. It is appropriate for accessory additions, relay wiring, lighting circuits, and general electrical repairs on production and specialty vehicles.

Key Features

Compatibility

Designed for use in surface vehicle electrical systems as an automotive primary wire. Suitable for 10 gauge terminal connections, inline connectors, and crimped or soldered automotive wiring applications.

Installation Notes

Disconnect the vehicle battery before beginning any wiring work to eliminate shock and short-circuit risk. Route wire away from sharp metal edges, exhaust components, and moving parts, using grommets where wire passes through body panels or firewall openings. Secure wire runs with appropriate automotive loom clips or tie straps at regular intervals to prevent chafing. Terminate connections with properly rated 10 gauge crimp terminals or soldered joints covered with heat-shrink tubing for a durable, moisture-resistant finish.
