Southwire 55667623 18 Awg Automotive Primary Wire 100 Ft Blue

Product Description

The SOUTHWIRE 55667623 is an 18 AWG automotive primary wire rated for use in surface vehicle electrical systems. It ships as a 100-foot spool with blue PVC outer insulation, making it a practical choice for circuit runs that benefit from color-coded identification. The conductor is a 16/30 stranded configuration, which provides flexibility for routing through tight spaces, panels, and conduit. Rated to 60 volts and a maximum temperature of 85 degrees C, this wire meets SAE standards for automotive and light-vehicle wiring applications. Licensed electricians, auto technicians, and fleet maintenance professionals install this type of wire for power distribution, accessory circuits, and trailer wiring work.

This wire is designed for surface vehicle electrical systems including passenger cars, trucks, trailers, and similar light-duty automotive applications. The blue color coding aids in circuit identification during installation and future service work. The spool format makes it well-suited for shop use where multiple runs of the same gauge are needed across a service day. It is appropriate for low-voltage DC circuit work operating within its 60-volt rating.

Installation Notes

Installation should be performed by a qualified automotive technician or licensed 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, heat sources, and moving components, using grommets or loom where wire passes through sheet metal. Follow applicable SAE and vehicle manufacturer wiring guidelines for connector type, fusing, and termination method.
