Ancor Dark Blue 10 AWG Tinned Copper Wire - 1,000'

Ancor Dark Blue 10 AWG Tinned Copper Wire in a 1,000-foot spool is the marine electrician's choice for reliable, long-lasting boat wiring installations. Whether you're upgrading an older vessel's electrical system, installing new circuits, or performing mid-season repairs, this heavy-gauge wire delivers the durability and safety standards demanded by saltwater and freshwater environments alike. After years on the water, experienced boaters know that electrical failures can strand you far from shore—this wire is engineered to prevent that scenario.

The 10 AWG tinned copper construction exceeds UL 1426, ABYC, and U.S. Coast Guard Charter boat (CFR Title 46) certification standards, ensuring compliance with marine electrical codes. Tinning the copper prevents oxidation and corrosion—critical in salt-spray and damp environments where bare copper rapidly deteriorates. The premium vinyl insulation is rated at 600 volts and handles the vibration, temperature cycling, and UV exposure inherent to marine applications. At 43.6 pounds, the full 1,000-foot spool provides ample length for complete system rewiring, multiple circuit runs, or backup spares without mid-project resupply issues.

This wire suits both DC house-bank circuits and AC shore-power installations on sailboats, powerboats, and commercial fishing vessels. The dark blue insulation makes polarity identification easier during installation and troubleshooting, reducing wiring errors that can damage sensitive electronics or create fire hazards. Professional marine electricians and DIY boaters restoring vessels use Ancor marine-grade wire as the foundation of systems they trust with safety and navigation equipment in remote waters.
