Ancor 12 AWG Tinned Copper Marine Primary Wire — 100 ft, Ultra-Flexible 600V

Ancor 106810 is a 100-foot spool of 12 AWG (3mm²) tinned, ultra-flexible marine primary wire in red, engineered for corrosion resistance and long-term durability in marine and harsh environments.

Built for boats, RVs, and other demanding electrical installations, this Ancor primary wire uses tinned copper stranding and Type 3 ultra-flexible construction to stand up to vibration, saltwater exposure, and repeated flexing. The premium vinyl insulation remains pliable down to -40° F/C and is rated for 600 volts, giving you a reliable conductor that meets or exceeds marine safety standards.

Why choose tinned copper wire for marine use?

Tinning the copper strands adds a protective layer that slows corrosion and minimizes electrolysis in salty or humid conditions. That improved longevity helps prevent voltage drop and connection failures over time without requiring oversized conductors.

• Resists corrosion from saltwater and humid climates
• Reduces risk of electrochemical degradation at terminations
• Maintains conductivity and flexibility over long service life

How does the wire handle flexing and vibration aboard boats?

This wire uses Type 3 ultra-flexible stranding, which distributes mechanical stress across many fine strands. The result is a conductor that resists metal fatigue and breakage where cables bend, vibrate, or route through tight chases.

• Fine multi-strand construction tolerates repeated movement
• Less prone to strand breakage at connection points
• Simplifies routing in confined or moving spaces

What does the insulation protect against and what are its ratings?

Ancor's proprietary vinyl insulation is formulated for marine exposure, resisting salt water, battery acid, oil, gasoline, and UV. It stays flexible in extreme cold and is heat-rated for both dry and wet conditions, supporting safe operation in varied environments.

• 600 V voltage rating for primary circuit applications
• 105° C dry / 75° C wet continuous temperature ratings
• Remains flexible down to -40° F/C and resists abrasion and chemicals

Does this wire meet marine safety and performance standards?

Yes. Ancor 106810 is built to exceed key marine standards, ensuring compatibility with commercial and recreational vessel requirements. Choosing certified wire simplifies inspections and supports long-term safety.

• Meets or exceeds UL 1426 marine wire standards
• Complies with US Coast Guard CFR Title 46 where applicable
• Meets ABYC recommendations for marine wiring

Who is this for? If you install, maintain, or upgrade electrical systems in boats, yachts, RVs, or other moisture-prone vehicles and equipment, this 100-foot spool of Ancor 12 AWG tinned primary wire is a practical choice. It suits DIY boat owners, marine electricians, and fleet technicians who need a dependable, code-compliant conductor that resists corrosion, holds up to vibration, and stays flexible in cold weather. Use it for battery feeds, fuse block runs, panel wiring, and general DC circuits where a durable, marine-grade 12 AWG cable is required.
