Southwire 55843833 Primary Wire 18 Awg 33 Feet Yellow

Product Description

The Southwire Company LLC 55843833 is an 18 AWG primary wire sold in a 33-foot length with yellow insulation. Primary wire of this gauge is a general-purpose single-conductor wire used for low-voltage DC wiring runs in automotive, trailer, marine, and light equipment applications. At 18 AWG, it handles moderate current loads suitable for accessory circuits, control wiring, and hookup work. Licensed electricians, HVAC technicians, and equipment installers reach for this wire when running short branch runs, connecting control components, or replacing damaged wiring segments. The carded packaging keeps the wire coiled and protected for jobsite or shop storage.

This wire is suited for use in residential and light commercial settings where a flexible, color-coded single-conductor is required for low-voltage control circuits or accessory wiring. Yellow insulation makes it easy to trace and identify within a wiring harness or panel. The 33-foot length provides enough stock for most single-run applications without excess waste. It is commonly used in HVAC control wiring, panel sub-feeds, trailer lighting circuits, and similar low-voltage hookup tasks.

Installation Notes

Installation should be performed by a qualified electrician or licensed trade professional in accordance with applicable NEC requirements. Always de-energize the circuit before making connections and verify the current rating of the circuit does not exceed the ampacity of 18 AWG wire under the applicable installation conditions. Use appropriate terminals, connectors, or soldered joints rated for the application. Avoid routing wire near sharp edges or heat sources without appropriate protective sleeving.
