Ancor White 18 AWG Tinned Copper Wire - 100'

Ancor White 18 AWG Tinned Copper Wire in 100-foot spools represents marine-grade electrical backbone for any vessel serious about reliability in saltwater environments. Built to exceed UL 1426, ABYC, and US Coast Guard Charter boat standards (CFR Title 46), this tinned copper construction resists corrosion where standard copper fails—a critical advantage for boats exposed to constant salt spray, battery acid, and fuel vapors.

The 18 AWG gauge handles moderate-load circuits throughout marine electrical systems—bilge pumps, nav lights, cabin wiring, and accessory installations. Premium vinyl insulation rated at 600V with dual-temperature performance (105°C dry, 75°C wet) means the wire functions reliably from engine room heat to submerged bilge conditions. The formulation stays flexible even at -40°F, preventing brittleness during winter storage or northern operation. This insulation also resists oil, gasoline, ultraviolet radiation, and mechanical abrasion—environmental stressors that degrade standard electrical wire within months on a working boat.

Weekend anglers upgrading fish finders, GPS units, or adding auxiliary charging systems rely on tinned copper to eliminate green corrosion at connection points. Commercial operators and serious offshore fishermen use Ancor wire because failure at sea is not an option—a corroded connection to your navigation system or engine instrumentation creates safety and legal liability. The 100-foot spool length accommodates full boat rewiring projects or supplies spare wire for repairs and modifications without excess waste.

Tinned copper wire costs more than bare copper, but marine electrical failure is exponentially more expensive. For vessels in saltwater service, this is not an optional upgrade—it is the correct electrical material.
