Ancor Grey 18 AWG Tinned Copper Wire - 35'

Ancor Grey 18 AWG Tinned Copper Wire — 35 feet — is a marine-grade electrical conductor engineered for saltwater applications where standard copper wire fails. Built to exceed UL 1426, ABYC, and US Coast Guard CFR Title 46 standards for charter and commercial vessels, this tinned copper wire delivers reliable power distribution in the harshest marine environments. The 18 AWG gauge handles mid-range electrical loads in bilge pumps, navigation lighting, and auxiliary circuits where flexibility and corrosion resistance are non-negotiable.

The tinned copper construction resists oxidation and salt spray far longer than bare copper, while premium vinyl insulation rates at 600V, 105°C dry, and 75°C wet — tolerating the thermal swings and moisture exposure of marine electrical systems. The wire remains flexibly even at extreme cold (-40°F), critical for deep-water operations and winter storage. The insulation resists salt water, battery acid, oil, gasoline, UV radiation, and mechanical abrasion — each a common failure point in boat wiring. The 35-foot length suits typical runs from battery to distribution panel, engine compartment circuits, or through-hull applications without excessive splicing.

This wire serves weekend anglers rewiring older boats, offshore charter operators upgrading aging systems, and DIY boaters executing electrical repairs or additions. Anyone replacing corroded original equipment or running new circuits in a saltwater environment benefits from Ancor's proven durability. Proper gauge selection matters: 18 AWG suits lower-amperage circuits; oversizing to heavier gauge adds unnecessary cost and bulk, while undersizing invites voltage drop and fire risk. Refer to ABYC guidelines for your specific circuit load before installation.
