Ancor Black 6 AWG Tinned Copper Wire - 250'

Ancor Black 6 AWG Tinned Copper Wire in a 250-foot spool is the marine-grade standard for powering everything from trolling motors and fish finders to navigation lights and bilge pumps on recreational and commercial vessels. After decades on the water, any experienced angler knows that electrical failures at sea are not merely inconvenient—they're dangerous.

This wire exists because saltwater environments demand corrosion resistance that standard copper simply cannot provide, and proper gauge selection is non-negotiable when lives and equipment depend on reliable current flow. The tinned copper construction sets this Ancor wire apart from bare copper alternatives. Tinning—a thin layer of solder applied to the copper strands—prevents oxidation and corrosion, critical factors in the harsh marine environment where salt spray, moisture, and UV exposure work constantly to degrade unprotected conductors.

At 6 AWG gauge, this wire handles high-current applications with minimal voltage drop over moderate distances, making it ideal for main battery runs, engine starting circuits, and large 12V or 24V loads. The 250-foot spool provides ample length for most single-boat projects, and the black PVC jacket offers additional UV and abrasion resistance during installation and operation. This wire is essential for anglers retrofitting older boats with modern electronics, installing new battery banks, or replacing degraded original wiring.
