Ancor 2 AWG Tinned Copper Battery Cable — 50 ft Red, Marine-Grade Flexible Insulation

Ancor 114505 is a 50-foot, 2 AWG (32mm²) red tinned-copper battery cable built for marine and harsh-environment power runs, combining ultra-flexible Type 3 stranding with premium vinyl insulation for long-lasting corrosion resistance.

This heavy-gauge battery cable is engineered for boats, RVs, and demanding outdoor installations where salt, vibration and temperature extremes shorten ordinary wire life. The conductor is made from fine tinned-copper strands to resist electrolysis and corrosion, while the high-performance vinyl jacket remains flexible in extreme cold and resists chemicals, UV and abrasion. It meets or exceeds UL 1426, ABYC and USCG Charter boat (CFR Title 46) standards to help you install a dependable DC power connection that stands up to wet, salty and moving environments.

How does this cable stand up to marine corrosion and electrolysis?

The conductor uses tinned copper stranding that provides an electrochemical barrier against corrosion, significantly reducing the rate of copper degradation in saltwater and humid conditions. Tinning also improves solderability and long-term electrical contact integrity.

• Tinned individual strands reduce galvanic corrosion on terminals and through bulkhead penetrations.
• Fine Type 3 stranding minimizes moisture pockets and helps maintain conductivity under vibration.
• Proven compliance with USCG and ABYC standards for marine wiring environments.

Is the insulation durable enough for battery compartments and exposed runs?

Ancor’s proprietary premium vinyl jacket is formulated for chemical, thermal and mechanical resistance so it performs in battery compartments and exposed bilge or deck areas. It retains flexibility down to -40°F/C and resists battery acid, oil, gasoline, UV rays and abrasion that commonly damage ordinary wire jackets.

• Rated 600 volts; heat ratings 105°C dry and 75°C wet for safe continuous operation.
• Flexible at very low temperatures to prevent cracking during cold-weather use.
• Resists acids, oils and fuels commonly found around engines and battery boxes.

What makes the 2 AWG, 50-foot length a practical choice for installations?

2 AWG (32mm²) provides a high current capacity suitable for main battery feeds, inverter connections and heavy accessory circuits while limiting voltage drop over runs up to 50 feet. The 50-foot spool length covers typical power distribution routes on midsize boats, RVs or utility vehicles without excess joins that can invite failure.

• Heavy gauge minimizes voltage loss for inverters, starters and high-draw loads.
• 50-foot length reduces the need for splices in long runs, improving reliability.
• Fine stranding and tinned finish ease routing and terminal terminations.

How should I terminate and maintain this wire for best performance?

Use appropriate marine-grade crimp terminals or soldered connections and seal terminations with heat-shrink or corrosion inhibitor to preserve the tinned surface and insulation. Regular visual checks and cleaning of terminals help maintain low-resistance contacts in saltwater environments.

• Crimp or solder with marine-rated lugs sized for 2 AWG conductors.
• Protect exposed lugs with shrink tubing and anti-corrosion paste where applicable.
• Inspect periodically for abrasion, chafe, or compromised insulation, especially near fittings.

Who is this for: This Ancor 114505 cable is aimed at boat owners, marine electricians, RV and off-grid system installers, and anyone needing a rugged, low-resistance DC power lead that resists corrosion, vibration and harsh chemicals. Choose this cable when you need a flexible, standards-compliant 2 AWG conductor for battery feeds, inverter hookups, or heavy accessory circuits where long-term reliability in wet, salty or mobile environments matters.
