Build a reliable, corrosion-resistant electrical system on your boat or vehicle with Ancor Marine Grade primary wire. This 14 AWG black wire is engineered to thrive in the harshest marine environments, exceeding UL 1426, US Coast Guard, and ABYC standards for safety and performance.

Ideal for DC negative returns or general low-voltage wiring, this 18-foot mini-spool gives you the perfect amount of premium wire for small projects, equipment upgrades, and targeted repairs without the waste of a massive bulk spool.

Technical Advantages

• Premium Tinned Copper: Every individual strand of the conductor is coated in pure tin. This critical barrier stops copper oxidation and corrosive "green rot" from traveling up the wire sheath in salty or humid conditions.

• Ultra-Flexible Type III Stranding: Built with high-strand-count copper that withstands constant engine vibration, hull flexing, and tight routing bends through standard conduit without cracking or fatiguing.

• Proprietary Vinyl Insulation: The heavy-duty jacket resists salt water, battery acid, oil, gasoline, and extreme heat. It stays flexible even down to -40°C and maintains its integrity in environments up to 105°C.

• True-to-Gauge Precision: Fully rated AWG (American Wire Gauge) sizing ensures maximum current carrying capacity and minimal voltage drop compared to undersized automotive alternatives.
