Ancor Red 18 AWG Tinned Copper Wire - 500'

Ancor Red 18 AWG Tinned Copper Wire - 500' is the marine electrician's foundation for reliable boat wiring systems. Whether you're upgrading navigation circuits, installing new battery banks, or running auxiliary power to deck equipment, this tinned copper conductor delivers the corrosion resistance and durability demanded by saltwater and freshwater environments alike. Built to exceed UL 1426, ABYC, and US Coast Guard Charter Boat (CFR Title 46) standards, it's the wire serious boaters and professionals specify when system reliability cannot fail.

The 18 AWG gauge and tinned copper construction resist oxidation and salt spray far longer than bare copper alternatives, critical for systems exposed to moisture and electrolytic corrosion. Premium vinyl insulation rated at 600V and 105°C ensures safe operation under deck loads and engine compartment heat. The 500-foot spool format reduces splice points in longer runs, lowering resistance losses and minimizing potential failure modes—a detail that matters when your bilge pump or cabin lighting depends on clean voltage delivery. Tinning also improves solderability and mechanical strength during termination, reducing installation labor and connection degradation over seasons of use.

Ideal for marine wiring upgrades, custom harness builds, and repair work on fishing boats, cruisers, and commercial vessels, this wire pairs seamlessly with Ancor terminals, breakers, and distribution panels. The red insulation color follows standard positive-circuit conventions, simplifying troubleshooting and future maintenance. At 5.35 pounds per 500-foot spool, it's manageable for single-person installation while maintaining substantial copper mass for low-resistance performance. Buy Ancor Red 18 AWG Tinned Copper Wire when you need marine-grade dependability that outperforms consumer-grade alternatives and lasts through decades of demanding conditions.
