Pacer Black 18 AWG Primary Wire - 100'

The Pacer Black 18 AWG Primary Wire in 100-foot length is purpose-built for marine electrical systems where reliability and corrosion resistance are non-negotiable. After years on the water, any serious boater knows that substandard wiring in saltwater or freshwater environments leads to dangerous voltage drops, electrical fires, and catastrophic system failures. This marine-grade primary wire is manufactured in the USA to exceed industry specifications, making it the trusted choice for rewiring projects, circuit repairs, and new installations on recreational and commercial vessels.

The 18 AWG gauge specification delivers optimal current-carrying capacity for low-voltage applications—bilge pumps, navigation lights, cabin lighting, and auxiliary systems—without unnecessary weight or bulk. Pacer's marine wire features enhanced insulation formulations that withstand UV exposure, extreme temperature swings, diesel fuel, and saltwater spray that would degrade standard automotive wire within months. The black outer jacket provides both durability and easy identification during troubleshooting. At 1.2 pounds for the full 100-foot spool, this wire remains manageable for single-handed installation while maintaining the gauge integrity necessary for safe current delivery and code compliance.

Whether you're rewiring an older center console, adding a new auxiliary power system, or upgrading aftermarket electronics, the Pacer Black 18 AWG Primary Wire pairs seamlessly with standard marine connectors, battery terminals, and panel-mounted switches. The 100-foot length provides adequate slack for most single-circuit runs or multiple shorter branches without wasteful excess. Professional installers and weekend DIYers alike depend on this wire's consistent diameter and insulation thickness to avoid mid-project surprises and ensure systems perform reliably for years.
