Ancor Dark Blue 18 AWG Tinned Copper Wire - 250'

Ancor Dark Blue 18 AWG Tinned Copper Wire – 250' is purpose-built for marine electrical systems where reliability and longevity are non-negotiable. After years on the water, any experienced boater knows that corroded or undersized wiring creates dangerous voltage drops, fires, and equipment failure when you need it most. This marine-grade wire meets or exceeds UL 1426, ABYC, and US Coast Guard Charter boat (CFR Title 46) standards, ensuring your vessel's electrical integrity in saltwater and freshwater environments alike.

The 18 AWG gauge provides optimal current-carrying capacity for branch circuits, lighting runs, and sensor connections throughout cabin and deck systems. Tinned copper construction resists oxidation far better than bare copper—critical when salt spray, humidity, and condensation are constant threats in a marine environment. Premium vinyl insulation is rated for 600V and 105°C, protecting against abrasion, UV exposure, and thermal stress in confined engine compartments and exposed topside locations. The 250-foot spool delivers enough wire for comprehensive rewiring projects, panel upgrades, or maintaining a well-stocked boat maintenance kit without frequent reorders.

This wire suits anglers and cruisers running electronics—GPS, fishfinders, VHF radios, navigation lights, and auxiliary systems—where voltage stability directly affects performance and safety. Use it for bilge pump circuits, battery interconnects, and any DC wiring that demands long-term reliability in harsh conditions. Its dark blue color aids identification in crowded junction boxes and makes troubleshooting faster when tracing circuits. Whether you're upgrading an aging vessel or building new systems to modern standards, Ancor's proven track record makes this the wire specification trusted by professional boat builders and serious recreational boaters.
