Ancor tinned copper marine wire 16 AWG (1 mm²) — 100 ft black, ultra-flex Type 3, 75°C wet rated

Ancor 102010 is a 100-foot spool of tinned-copper, 16 AWG (1 mm²) marine-grade wire with ultra-flexible Type 3 stranding and premium vinyl insulation built for corrosion resistance and durability.

This 16 AWG black wire is designed for demanding marine and outdoor electrical work where exposure to salt, vibration, temperature swings and chemicals is common. The conductor is made from many fine copper strands that are tinned to slow corrosion and improve long-term conductivity, while the proprietary vinyl jacket remains pliable in cold weather and resists oils, gasoline, UV and battery acid. The result is a long-lasting, serviceable wire suited to boats, RVs, off-grid systems and other environments where reliability matters.

How does this wire stand up to salty, wet environments?

The copper strands are individually tinned to create a protective coating that inhibits electrolysis and corrosion when exposed to moisture and salt air. The insulation is rated for wet conditions and holds flexibility in freezing temperatures, reducing stress on connections.

• Tinned stranded conductor for improved corrosion resistance
• Insulation rated for 75°C wet operation and resists salt water
• Proprietary vinyl stays flexible down to -40°F/°C

Will this wire handle vibration and repeated movement?

Yes — the Type 3 ultra-flex stranding is engineered to tolerate bending and repeated motion without breaking. That makes it suitable for engine spaces, wiring harnesses, or locations that experience constant vibration.

• Fine multi-strand construction reduces metal fatigue
• Superior flexibility for routing through tight spaces
• Durable against abrasion from chafe and movement

What electrical and safety ratings should I expect?

This cable is built to recognized marine and safety standards, rated for 600 volts and tested for high-temperature performance in dry conditions. It meets or surpasses UL 1426, USCG Charterboat (CFR Title 46) and ABYC criteria for marine wiring.

• 16 AWG (1 mm²) conductor — nominal current capacity per application needs
• 600 V insulation rating, 105°C dry, 75°C wet temperature ratings
• Compliance with UL, US Coast Guard, and ABYC standards

How is the insulation resistant to chemicals and sunlight?

The premium vinyl jacket resists common chemical exposures found around boats and vehicles, such as fuel, oil and battery acid, and it includes UV resistance to reduce degradation from sunlight. This extends the service life of exposed runs and connections.

• Chemical-resistant jacket repels gasoline, oil and battery acid
• UV-stable compound prevents cracking and brittleness outdoors
• Heat and abrasion resistant for demanding installations

Who this is for: technicians, DIYers and marine owners who need a reliable, long-lasting 16 AWG wire for boat systems, RV wiring, solar or mobile electrical projects will appreciate the combination of tinned copper strands and flexible, chemical-resistant insulation. Choose this spool when you want wiring that tolerates vibration, salt spray, temperature extremes and routine wear while conforming to established marine safety standards.
