Ancor Red 18 AWG Tinned Copper Wire - 250'

Ancor Red 18 AWG Tinned Copper Wire in 250-foot spools is the marine electrician's choice for reliable, corrosion-resistant wiring in saltwater and freshwater vessels. Whether you're rewiring a fishing boat's console, upgrading trolling motor circuits, or installing navigation lighting, this wire meets or exceeds UL 1426, ABYC, and US Coast Guard Charter Boat (CFR Title 46) standards—the same stringent requirements applied to commercial fishing fleets and offshore vessels. Red insulation helps identify positive circuits in complex wiring systems, reducing installation errors and troubleshooting time.

The 18 AWG gauge provides optimal balance for low-voltage and moderate-current marine applications, handling up to 25 amps at typical boat voltages without excessive voltage drop over moderate distances. Tinned copper construction resists oxidation and corrosion far better than bare copper, a critical advantage in salt-spray environments where unprotected wire fails prematurely. Premium vinyl insulation is rated at 600V and rated to 105°C, providing protection against mechanical abrasion, UV exposure, and thermal cycling from engine compartments or exposed deck runs. The 250-foot spool length minimizes waste while supplying enough wire for comprehensive rewiring projects or multiple circuit installations.

Serious boaters, commercial fishing operations, and marine technicians rely on Ancor wire for permanent installations where reliability directly impacts safety and equipment longevity. Use this wire for battery circuits, bilge pump wiring, through-hull fittings, and any DC or low-voltage system where exposure to moisture and salt is inevitable. Pair with marine-grade connectors and crimp terminals (sold separately) and follow ABYC guidelines for circuit protection and wire sizing to ensure Coast Guard compliance and warranty protection on your vessel's electrical systems.
