Ancor Black 18 AWG Tinned Copper Wire - 500'

The Ancor Black 18 AWG Tinned Copper Wire – 500' is a marine-grade electrical wire built for harsh saltwater environments where standard wiring fails. This 500-foot spool delivers the reliability demanded by serious boaters, whether you're running electronics on a weekend fishing boat or powering complex systems on a commercial or offshore vessel. Constructed with tinned copper conductor and premium vinyl insulation, this wire exceeds UL 1426, ABYC, and US Coast Guard Charter boat standards, making it the specification choice for any marine electrical installation that demands longevity and safety.

The 18 AWG gauge handles circuits requiring moderate current capacity—ideal for running LED navigation lights, cabin lighting, bilge pumps, and low-draw accessory circuits common in recreational and commercial marine applications. The tinned copper construction resists corrosion that would degrade standard copper wire in the salt air and spray environment typical of coastal boating. Rated at 600V with insulation maintaining flexibility at temperatures as low as -40°F, the wire stays pliable during cold-weather launch and storage, unlike brittle alternatives. The vinyl jacket resists salt water infiltration, battery acid spills, fuel contact, engine oil exposure, abrasion from deck hardware and through-hull fittings, and UV radiation—the spectrum of threats marine electrical systems face.

This spool length suits both new builds and system upgrades where a single run or multiple shorter circuit runs are needed without excessive waste. Anglers upgrading fish finders, GPS plotters, or autopilot systems will find this wire meets the same standards required for safe DC power distribution in electrical systems. The 500-foot length provides adequate supply for substantial wiring projects while remaining manageable for storage in tight engine compartments or electrical lockers aboard most vessel sizes.

Marine-grade wire is not a cosmetic upgrade—it is a safety requirement in saltwater environments where corrosion-related electrical failures create fire and navigation hazards. Ancor's reputation in the marine industry rests on consistent adherence to these standards across their product line, making this wire a dependable choice for any boater prioritizing system reliability and regulatory compliance over budget alternatives.
