Ancor Green 18 AWG Tinned Copper Wire - 500'

Ancor Green 18 AWG Tinned Copper Wire – 500' is a marine-grade electrical conductor engineered for long-term saltwater durability and reliability in demanding boating environments. This 500-foot spool delivers the corrosion resistance and mechanical strength needed for permanent marine wiring installations, from center console boats to offshore fishing vessels and cruising sailboats. Manufactured to exceed UL 1426 and ABYC standards—the same specifications required for U.S. Coast Guard certified charter vessels—Ancor's tinned copper construction resists the accelerated corrosion that bare copper wire experiences in salt air and spray.

The 18 AWG gauge provides optimal flexibility for tight runs and terminal connections while maintaining suitable amperage capacity for common 12V and 24V marine circuits: nav lights, cabin lighting, auxiliary pumps, and instrument feeds. Premium vinyl insulation rated at 600V and 105°C (dry) / 75°C (wet) stays supple even in extreme cold down to −40°F, resisting salt water, battery acid, oil, gasoline, UV radiation, and mechanical abrasion—factors that degrade standard electrical wire quickly in marine service. The ultra-flex construction allows multiple bends without cracking the insulation, critical for installations where wire must navigate through tight compartments, alongside rigging, or through engine rooms subject to vibration.

Serious boaters and marine electricians specify Ancor tinned copper wire for systems designed to last decades rather than seasons. Weekend fishermen upgrading electronics, cruising sailors rewiring for modern autopilots and watermakers, and commercial operators maintaining regulatory compliance all depend on this wire's proven track record. The 500-foot length covers most single-system installations—battery banks, switch panels, thruster circuits, or complete auxiliary systems—with sufficient reserve for terminations and future modifications. Marine-specific wire ensures your electrical system won't become a corrosion liability in the harsh saltwater environment where standard copper wire fails within seasons.
