Ancor Black 16 AWG Tinned Copper Wire - 500'

Ancor Black 16 AWG Tinned Copper Wire in 500-foot spools sets the standard for marine electrical wiring. Built to exceed UL 1426 and ABYC standards—the same certifications required for U.S. Coast Guard charter boats—this tinned copper wire delivers corrosion resistance and flexibility that hold up in salt water, extreme cold, and harsh offshore environments where standard wiring fails.

The 16 AWG gauge handles circuits up to 20 amps on vessels under 65 feet, making it ideal for running navigation lights, bilge pumps, battery banks, and deck equipment. Premium vinyl insulation is rated 600V with a wet operating temperature of 75°C, maintaining flexibility even at -40°F. The tinned copper core resists battery acid, salt spray, oil, gasoline, UV radiation, and abrasion—eliminating the green oxidation and brittleness that plague uncoated copper in marine applications. At 500 feet per spool, a single roll covers most re-wiring projects on center console boats, sailboats, and fishing vessels.

Weekend anglers and professional captains rely on Ancor wire for reliability at sea. Whether upgrading aging electrical systems, installing new fish finders and autopilot systems, or replacing corroded rigging, this marine-grade wire eliminates voltage drop and fire hazard. The 500-foot spool reduces splice points and labor on larger boats while remaining practical for smaller craft where excess wire storage is tight.

Marine electrical codes require tinned copper for permanence and safety below deck. Ancor's formulation exceeds these baselines, making it the specification wire for original equipment manufacturers and yards performing class-certified repairs. The 7-pound spool weight reflects the density and gauge; plan accordingly for transport and storage on larger vessels.
