Ancor Brown 18 AWG Tinned Copper Wire - 1,000'

Ancor Brown 18 AWG Tinned Copper Wire - 1,000' is the marine-grade electrical backbone that keeps your vessel's systems running safely and reliably for years. Whether you're wiring navigation lights, running shore power connections, or installing custom electronics, this tinned copper wire meets or exceeds every standard that matters—UL 1426, ABYC, and US Coast Guard CFR Title 46 requirements for charter boats. Built for salt spray, vibration, and the corrosive marine environment, it's the wire serious boaters and professional installers specify for permanent installations where failure isn't an option.

The 18 AWG gauge delivers optimal ampacity for branch circuits, lighting, and low-power sensor wiring without unnecessary bulk. Tinned copper construction—a tin coating applied to pure copper—provides superior corrosion resistance compared to bare copper, especially critical in saltwater and humid environments where oxidation accelerates wire degradation and resistance buildup. The premium vinyl insulation is rated at 600V and 105°C, allowing safe operation in engine rooms, cabin runs, and exposed deck installations. This full 1,000-foot spool minimizes splice points, reducing failure risk and ensuring consistent voltage delivery across long cable runs common in cruising sailboats and larger powerboats.

This wire is ideal for bilge pumps, cabin lighting circuits, instrument clusters, and any permanent 12V or 24V DC system where reliability trumps cost. The generous 1,000-foot length makes it economical for new builds, major rewiring projects, or maintaining a well-stocked marine electrical inventory. Installation is straightforward with standard crimp terminals and marine-grade connectors; the supple insulation resists cracking even at sub-freezing temperatures. Boaters seeking Coast Guard compliance, insurance approval, or simple peace of mind during extended cruising choose Ancor marine wire—it's built to outlast the vessel itself.
