Ancor Grey 16 AWG Tinned Copper Wire - 500'

The Ancor Grey 16 AWG Tinned Copper Wire – 500' is a marine-grade electrical conductor engineered for serious boaters who demand reliability in harsh saltwater environments. This 500-foot spool of 16 AWG tinned copper wire exceeds UL 1426 and ABYC standards, meeting US Coast Guard Charter boat (CFR Title 46) specifications for critical electrical installations on vessels. Tinned copper construction resists corrosion far better than bare copper, making this wire the preferred choice for permanent wiring in marine battery systems, electronics, navigation equipment, and engine compartments where salt spray and moisture are constant threats.

The 16 AWG gauge delivers sufficient ampacity for moderate-current circuits while maintaining flexibility in tight installation spaces—critical when routing wiring through cabin walls, under gunwales, or around engine blocks. Premium vinyl insulation is rated 600V at 105°C dry and 75°C wet, ensuring safe operation in both engine room heat and below-deck moisture. The insulation remains flexible even at -40°F, a significant advantage for year-round boaters in northern waters or those storing vessels in unheated sheds. Chemical resistance to salt water, battery acid, oil, gasoline, and UV radiation means this wire won't degrade from exposure to fuel spills, bilge conditions, or unprotected deck routing.

This 500-foot spool suits weekend fishermen upgrading trolling motor wiring, cabin lighting circuits, or radio installations, as well as offshore anglers and charter operators performing comprehensive electrical system upgrades. The 6.9-pound spool is manageable for single-person installation while providing enough length to wire a mid-size vessel or service multiple circuits without splicing. Boaters who have experienced corroded marine electrical failures understand the true cost of cutting corners on wire quality—Ancor tinned copper eliminates that risk at the source.
