Ancor #10 Red 250' Spool Tinned Copper

The Ancor #10 Red 250' Spool Tinned Copper wire is the marine electrician's trusted choice for reliable, corrosion-resistant boat wiring. Whether you're upgrading your vessel's electrical system, running new circuits to nav lights, or rewiring a cabin retrofit, this 10 AWG tinned copper conductor delivers the durability and safety margins that professional and recreational boaters depend on. Marine-grade wire isn't optional—it's the foundation of a safe electrical system in a saltwater environment.

Ancor's tinned copper construction exceeds UL 1426, ABYC, and US Coast Guard specifications for chartered vessels (CFR Title 46)—standards that exist because electrical failures at sea carry life-and-death consequences. The tin coating bonds directly to the copper strands, preventing oxidation and corrosion that would otherwise degrade conductivity over years of exposure to moisture, salt spray, and vibration. At 10 AWG (5mm), this wire handles up to 55 amps at 12V DC in typical boat installations, making it suitable for main distribution runs, thruster circuits, and high-draw systems. The 250-foot spool provides flexibility for larger projects without mid-run splices.

This wire is essential for saltwater anglers, cruisers, and commercial operators who cannot afford electrical downtime or safety compromises. Red insulation aids circuit identification and meets standardized marine color coding for positive DC conductors. The spool format stores compactly and allows you to cut precise lengths for bilge pumps, battery banks, main switchboards, and thruster installations without waste. Pair with marine-grade breakers, switches, and connectors rated to the same standards for a system that performs year after year in demanding conditions.
