Ancor Marine Battery Cable, 50 Feet, 6 AWG, Black — Tinned Copper, Flexible

The Ancor 112005 is a 50-foot, 6-gauge tinned copper marine battery cable designed for long-lasting, flexible power runs in saltwater and rugged boat environments.

Built to withstand vibration, moisture and chemical exposure, this black 6 AWG wire provides a reliable connection for batteries, inverters, windlasses and other DC systems on boats and marine vehicles. Its fine-stranded, tinned copper conductors combine conductivity with corrosion resistance, while the premium vinyl jacket maintains flexibility across extreme temperatures. The cable exceeds common marine safety standards, making it a practical choice for professional installers and DIY boat owners who need durable cable with predictable performance.

How does this cable resist corrosion and marine wear?

The Ancor 112005 uses individually tinned copper strands and an ultra-flexible Type 3 stranding pattern to slow oxidation and tolerate constant motion. Tinning protects each strand from salt and humidity, and the jacket repels chemicals that would otherwise degrade connections.

• Tinned copper strands for improved corrosion protection
• Type 3 flexible stranding reduces metal fatigue under vibration
• Vinyl insulation resists saltwater, battery acid, oil and gasoline

What electrical and temperature ratings should I expect?

This 6 AWG cable is rated for 600 volts and built to tolerate high operating temperatures and cold starts. The insulation is specified for 105°C in dry conditions and 75°C in wet conditions, and it remains flexible down to -40°F/C for reliable routing in tight or exposed locations.

• 600 V insulation rating suitable for common marine DC applications
• 105°C dry / 75°C wet thermal ratings for stable performance
• Flexibility maintained to -40°F/C for cold-weather installations

Will this cable meet marine codes and professional standards?

Yes — the cable is manufactured to exceed relevant marine safety and construction standards, which helps when complying with vessel wiring rules. It surpasses UL 1426 and aligns with ABYC and U.S. Coast Guard charter-boat requirements, supporting both regulatory compliance and safe installation practices.

• Exceeds UL 1426 marine wire standard
• Meets ABYC recommendations for battery and DC wiring
• Compliant with U.S. Coast Guard charter-boat electrical criteria

How does the cable perform during installation and daily use?

Fine stranding and a supple jacket make routing through tight conduits and around bends straightforward, minimizing stress at lugs and terminals. For boaters, that translates to fewer brittle connections, easier terminations, and longer service life even with constant engine vibration and UV exposure.

• Ultra-flexible construction eases bending and termination
• Rugged jacket resists abrasion and UV damage in exposed runs
• Durable under repeated vibration—reduces the chance of broken strands

Who is this for: The Ancor 112005 6 AWG battery cable is aimed at marine technicians, boat owners upgrading or replacing battery and shore power runs, and anyone needing a resilient, flexible 50-foot cable for DC systems. It's well suited for battery-to-bus wiring, inverter feeds, windlass and trolling-motor installations where corrosion resistance, code compliance and long-term flexibility matter most.
