Ancor Pink 18 AWG Tinned Copper Wire - 500'

Ancor Pink 18 AWG Tinned Copper Wire in 500-foot spools is the marine electrician's choice for reliable, long-lasting vessel wiring. Whether you're running power circuits through a fishing boat, restoring a saltwater cruiser, or upgrading navigation and safety systems, this tinned copper wire meets the same rigorous standards that keep commercial charter vessels compliant with US Coast Guard regulations. The 500-foot length provides ample coverage for most single-run applications, from engine compartment work to cabin rewiring projects.

Built with premium vinyl insulation rated at 600V and 105°C, the Ancor Pink 18 AWG wire exceeds UL 1426, ABYC (American Boat and Yacht Council), and CFR Title 46 marine standards—the gold standard for marine electrical safety. Tinned copper construction resists corrosion from saltwater exposure far better than bare copper, making it essential for coastal and offshore use where oxidation and green corrosion can compromise circuit integrity. The 18 AWG gauge balances flexibility for routing through tight spaces with adequate ampacity for mid-range loads, making it ideal for auxiliary systems, lighting circuits, and instrument panel connections.

Boaters upgrading older aluminum or uninsulated wiring, or those installing new systems on a fresh build, will appreciate the durability that tinned copper delivers in marine environments. The 500-foot spool reduces splice points and waste, critical when running circuits from battery banks to bilge pumps, charging systems, or throughout cabin infrastructure. Compatible with standard marine-grade connectors and terminals, this wire integrates seamlessly into ABYC-compliant electrical systems and withstands the vibration, humidity, and temperature cycling inherent to life on the water. Installation is straightforward with basic marine electrical tools, and the pink color coding helps crews visually track circuit runs during troubleshooting and future upgrades.
