Ancor Yellow 16 AWG Primary Wire - 100'

Ancor Yellow 16 AWG Primary Wire in 100-foot spools is purpose-built marine electrical wire designed to withstand the harsh saltwater environment. Manufactured from tinned copper stranding, this marine-grade primary wire resists corrosion and electrolysis—two of the most destructive forces in boat electrical systems. The ultra-flexible Type 3 stranding design accommodates vibration and constant flexing inherent to marine applications, preventing insulation fatigue that leads to shorts and circuit failures.

The 16 AWG gauge is rated for circuits up to approximately 15–20 amps at typical marine voltages, making it suitable for lighting, accessory wiring, and auxiliary systems throughout cabin and bilge applications. Ancor's proprietary premium vinyl insulation maintains flexibility in extreme cold and resists salt water, battery acid, oil, gasoline, and ultraviolet radiation—critical durability factors in coastal and offshore environments. The 600-volt insulation rating provides substantial safety margin for 12-volt and 24-volt marine DC systems. Each 100-foot spool ships in a compact 4-inch cube, making storage aboard practical without consuming valuable space.

Weekend anglers upgrading bilge pumps, running new cabin lighting, or adding fish-finder power will appreciate the reliability; serious offshore operators rely on Ancor primary wire for critical systems where electrical failure compromises safety. This yellow wire simplifies troubleshooting in wiring harnesses and meets American Boat & Yacht Council (ABYC) standards for marine electrical installation. Stock multiple spools for system redundancy and future projects—marine electrical work rarely fits neatly into a single run.
