Ancor White 12 AWG Tinned Copper Wire - 400'

The Ancor White 12 AWG Tinned Copper Wire – 400' spool is a marine-grade electrical conductor engineered for saltwater environments where standard automotive or household wire fails. Built to exceed UL 1426, ABYC, and US Coast Guard CFR Title 46 standards, this tinned copper wire delivers the corrosion resistance and electrical reliability that offshore and inshore boaters depend on for safe, long-term installations in harsh marine conditions.

The 12 AWG gauge handles moderate current loads typical of navigation lights, bilge pump wiring, and cabin circuits, while the premium vinyl insulation is rated 600V at 105°C dry and 75°C wet—far exceeding the demands of typical marine DC systems. Tinned copper construction prevents galvanic corrosion and oxidation that plague bare copper in salt air, and the flexible insulation remains supple even at extreme cold (-40°F), resisting battery acid, gasoline, oil, UV radiation, and abrasion. At 400 feet per spool, a single roll covers most complete rewiring projects on fishing boats, cruisers, or sport-fishing vessels.

This wire suits weekend fishermen running basic electrical upgrades as much as serious offshore anglers installing redundant systems or full boat rewires. Anglers who've experienced corroded connections mid-trip recognize the value of marine-specific wire—it eliminates the false economy of adapting automotive wire that oxidizes within months in saltwater. Whether you're installing new electronics, replacing failing circuits, or building auxiliary power runs, Ancor's marine-grade construction ensures connections that stay corrosion-free and carry full rated current throughout the life of the vessel.
