Ancor Tinned Copper Primary Wire 14 AWG Red — 100 ft Marine-Grade, Ultra-Flexible, 600V

Ancor Tinned Copper Primary Wire, 14 AWG, Red, 100 ft is a marine-grade, ultra-flexible electrical cable designed to resist corrosion, vibration, and harsh environmental exposure while carrying up to 600 volts.

This 100-foot spool of 14 AWG primary wire from Ancor combines finely stranded tinned copper conductors with a durable vinyl jacket formulated for marine conditions. The tinned stranding improves resistance to electrochemical corrosion and the Type 3 ultra-flexible construction reduces fatigue where wires bend or vibrate. The insulation remains pliable in extreme cold and stands up to saltwater, fuels, battery acid, sunlight and mechanical wear.

How does this wire handle salty, humid, or wet conditions?

Corrosion resistance comes from the tinned copper strands which slow oxidation and electrolysis compared to bare copper. The insulation is specified for wet environments and maintains electrical integrity at elevated temperatures, making it suitable for exposed marine installations when paired with proper connections and protection.

• Tinned copper stranding reduces corrosion and prolongs conductor life.
• Insulation rated for 75°C (wet) resists moisture penetration and breakdown.
• UV-resistant jacket prevents sun-related degradation on deck runs.

Will this wire withstand continuous movement and vibration aboard a boat?

Yes — the Type 3 ultra-flexible stranding is engineered to bend repeatedly without breaking, lowering the chance of conductor fatigue in areas that flex or vibrate. That flexibility also makes routing and termination easier in tight spaces.

• Type 3 stranding improves flex life around pulleys and through grommets.
• Fine individual strands allow smoother bends and reduce stress risers.
• Works well in engine compartments and near vibration sources.

What temperature and voltage limits should I expect from this cable?

The Ancor primary wire carries a 600-volt rating and is built to perform across a wide thermal range. The jacket and conductor are rated for high-dry and moderate-wet temperatures, so the cable retains safety margins for most onboard electrical circuits.

• Rated 600 V for general marine electrical systems.
• Dry temperature rating up to 105°C (221°F) and wet rating up to 75°C (167°F).
• Remains flexible down to -40°F/-40°C for cold-weather use.

How does this product meet marine and safety standards?

Ancor’s wire is manufactured to exceed recognized maritime and electrical standards, offering confidence for commercial and recreational applications. Using compliant wire simplifies inspections and helps maintain safe installations when paired with correct terminals and routing practices.

• Meets or exceeds UL 1426 electrical wire requirements.
• Complies with ABYC recommendations for marine wiring.
• Designed to satisfy USCG requirements for certain charter-boat installations (CFR Title 46).

Who is this for? This 100 ft spool of Ancor 14 AWG tinned-copper primary wire is intended for boat owners, marine electricians, fleet operators, and anyone fitting or repairing DC and low-voltage AC circuits in wet or corrosive environments. It’s a practical choice where long runs, frequent movement, or exposure to saltwater and sunlight demand a cable that resists corrosion, stays flexible in cold climates, and complies with common marine wiring standards. Use it for battery leads, accessory circuits, cabin power runs, and other onboard wiring where a dependable 14 AWG marine-grade conductor is required.
