Ancor #10 Black 100' Spool Tinned Copper Wire

Ancor #10 Black 100' Spool Tinned Copper Wire is the marine electrician's foundation for reliable vessel wiring. Whether you're rewiring a cabin cruiser, upgrading a fishing boat's electronics, or replacing corroded connections on a saltwater platform, this tinned copper wire delivers the corrosion resistance and longevity that freshwater and saltwater environments demand. Built to exceed UL 1426, ABYC, and US Coast Guard CFR Title 46 charter boat standards, it's the specification choice for professionals and serious boaters who understand that electrical failures at sea are non-negotiable risks.

The #10 AWG gauge provides optimal amperage capacity for primary circuits—battery banks, main engine starts, and high-load accessories—while remaining manageable for hand installation in tight bilge and helm spaces. Tinned copper construction resists oxidation far longer than bare copper, a critical advantage in the constant humidity and salt spray of marine service. The premium vinyl insulation jacket protects against chafing, UV degradation, and galvanic corrosion when routed through metal conduit or alongside dissimilar metals. At 100 feet per spool, one roll handles most single-circuit runs on mid-size to large vessels without splicing, reducing failure points and simplifying troubleshooting.

This wire suits battery-to-alternator runs, main distribution panels, and trolling motor circuits where amperage demands and environmental exposure are high. Installation is straightforward—tin-plated conductors accept solder and crimp terminals reliably, and the black color simplifies negative/return identification on traditional boats. The 4.46 lb spool weight makes it portable for jobsites and easy to manage in confined spaces. Coast Guard-compliant boats, commercial fishing vessels, and any owner serious about electrical safety will find this tinned copper wire the standard against which others are measured.
