Ancor Grey 18 AWG Tinned Copper Wire - 100'

Ancor Grey 18 AWG Tinned Copper Wire in 100-foot spools is a marine-grade electrical conductor engineered for harsh saltwater environments. This tinned copper wire exceeds UL 1426, ABYC, and US Coast Guard (CFR Title 46) standards, making it the specification choice for boat electrical systems where reliability directly affects safety. The tinned copper construction resists corrosion far longer than bare copper, a critical advantage when exposed to salt spray, battery acid, and constant moisture that quickly compromises standard marine wiring.

The 18 AWG gauge provides ideal current-carrying capacity for low-voltage DC circuits common in modern marine electrical systems—navigation lighting, bilge pumps, radio feeds, and auxiliary accessory circuits. Insulation is premium vinyl rated at 600V with dry temperature tolerance to 105°C and wet tolerance to 75°C, delivering margin above typical marine operational demands. Critically, this wire remains flexible even at extreme cold (-40°F/-40°C), resisting salt water, battery acid, oil, gasoline, heat, abrasion, and ultraviolet radiation. The combination of these properties means this wire maintains integrity through seasonal temperature swings and prolonged UV exposure on deck or in engine compartments.

Weekend anglers upgrading boat wiring, offshore fishing operations running complex electrical systems, and marine technicians performing certification work all specify Ancor tinned copper wire. The 100-foot length covers most single-run applications—from helm instruments to through-hull fittings—without excessive waste or the need for multiple spools. For any boat application where electrical integrity cannot fail, tinned copper wire is the marine standard that coastal boaters and commercial operators depend on.
