Ancor Black 18 AWG Tinned Copper Wire - 100'

The Ancor Black 18 AWG Tinned Copper Wire – 100' is a marine-grade electrical conductor engineered for harsh saltwater environments where standard automotive or household wire fails. This 100-foot spool of tinned copper wire meets or exceeds UL 1426, ABYC, and US Coast Guard CFR Title 46 standards, making it the correct choice for any boat electrical system requiring reliability in extreme conditions.

The 18 AWG gauge is ideal for low-current circuits, sensor wiring, and auxiliary systems where space and weight matter. Premium vinyl insulation rated at 600V handles typical boat electrical loads while remaining flexible even at –40°F, critical for cold-weather operation or northern climates. The tinned copper construction resists salt water corrosion, battery acid, oil, gasoline, UV radiation, and abrasion—the exact failure modes that destroy standard copper wire in marine service. This means longer intervals between inspections and replacement, translating to lower maintenance costs and fewer mid-season electrical failures.

Anglers, cruisers, and commercial operators rely on Ancor marine wire for bilge pump circuits, GPS/chartplotter feeds, fish finder connections, and navigation light wiring. Whether you're running weekend fishing trips in coastal waters or maintaining a working charter boat, this wire handles repeated vibration, temperature swings, and salt spray without degradation. The 100-foot length covers most small-to-mid-sized boat projects or serves as inventory for ongoing repairs.

For any permanent boat wiring—whether new installation or replacement—marine-grade tinned copper wire is non-negotiable. Standard copper wire oxidizes in salt air and corrodes at connections, creating voltage drops and fire hazards. Ancor's compliance with Coast Guard and ABYC standards ensures your electrical system meets inspection requirements and insurance standards.
