Southwire 55667433 Primary Wire 18 Awg 33 Ft Red

Product Description

The Southwire Company LLC 55667433 is an 18 AWG primary wire rated for general-purpose low-voltage wiring applications. Measuring 33 feet in length and finished in red, this single-conductor wire is suitable for automotive, marine, HVAC control, and light electrical wiring tasks. The 18-gauge conductor size handles low-current circuits efficiently, making it a practical choice for thermostat wiring, control panel runs, and accessory connections. It is packaged on a card for clean storage and easy dispensing on the job. Licensed electricians, HVAC technicians, and automotive service professionals commonly use this wire for short-run control and signal circuits.

This primary wire is used in residential and light commercial applications where a reliable, color-coded conductor is needed for low-voltage control wiring. The red jacket aids in circuit identification when running multiple conductors in a panel or wiring harness. Typical install scenarios include HVAC control board connections, automotive accessory wiring, marine electrical systems, and trailer wiring. It is sold in a 33-foot carded format, sized for single-job or repair use rather than bulk coil applications.
