Ancor 18/2 250' Spool Tinned Copper Duplex

The Ancor 18/2 250' Spool Tinned Copper Duplex cable is a marine-grade electrical wire engineered for reliable power distribution aboard vessels of all sizes. After years running systems in saltwater environments, experienced boaters know that standard copper wire fails quickly when exposed to corrosive salt spray and moisture. This duplex configuration—two conductors in a single jacket—simplifies installation in tight spaces while delivering the redundancy needed for critical 12V DC circuits like navigation lights, bilge pumps, and auxiliary systems.

Built from tinned copper stranding, this cable resists oxidation and corrosion far better than bare copper alternatives, extending service life by years in harsh marine conditions. The 18 AWG gauge (2 × 0.8mm conductors) supports moderate-load circuits up to approximately 20 amps under ideal conditions, making it suitable for secondary systems and sensor wiring. The flat duplex design reduces bulk compared to round twin-lead cable, fitting neatly along cabin sole, behind panels, and through tight routing channels—a practical advantage when retrofitting older vessels or managing cable runs in modern cabin layouts. The 250-foot spool ensures sufficient length for complete system rewiring without splices on most recreational and commercial boats.

Boaters upgrading aging wiring, installing new electronics, or replacing corroded factory harnesses will find this cable meets ABYC (American Boat and Yacht Council) marine electrical standards. The red and yellow primary conductors in a white common jacket follow industry color conventions, simplifying identification during installation and future troubleshooting. Whether you're wiring a fishing boat's navigation suite, a cruising sailboat's auxiliary systems, or a commercial work vessel, the Ancor 18/2 duplex cable delivers the corrosion resistance and electrical reliability that saltwater environments demand.
