Ancor Yellow 18 AWG Tinned Copper Wire - 250'

Ancor Yellow 18 AWG Tinned Copper Wire in 250-foot spools is the marine-grade standard for reliable electrical installations aboard vessels of all sizes. Built to exceed UL 1426, ABYC, and U.S. Coast Guard CFR Title 46 standards, this tinned copper conductor delivers the corrosion resistance and conductivity that saltwater environments demand. Whether running power circuits, navigation systems, or auxiliary equipment, this wire handles the electrical loads and environmental stresses that come with time on the water.

The 18 AWG gauge suits mid-range circuit protection and lighting applications, with tinned copper construction providing superior oxidation resistance compared to bare copper. Premium vinyl insulation is rated 600V and maintains flexibility from -40°F to operating conditions, resisting salt spray, battery acid, diesel fuel, oil, gasoline, UV radiation, and mechanical abrasion. The 250-foot length accommodates full-boat wiring projects or repair stock for extended cruising. Marine electricians and DIY boaters value the predictable performance and longevity that comes from wire engineered specifically for salt-air exposure and deck-mounted equipment.

This wire serves both weekend fishermen upgrading cabin systems and serious offshore operators maintaining critical navigation and engine monitoring circuits. It is equally suited for new builds, refit projects, or emergency repairs at sea. The tinned copper core and UV-resistant jacket eliminate the maintenance burden of bare copper wire in harsh marine conditions, protecting both the investment in electrical components and the safety systems that depend on reliable conductivity.

Marine wire specifications matter because undersized or corroded conductors create voltage drop, fire risk, and equipment failure at sea. Ancor's compliance with Coast Guard standards ensures your installation meets insurance and regulatory requirements, while the 250-foot spool format reduces connector joints and simplifies troubleshooting during operation or repair cycles.
