CONEPY 12 Gauge Marine Wire 15.2 m Duplex - Tinned Copper, Flexible UV-Resistant Jacket

CONEPY 12 Gauge Marine Wire 50FT is a 12/2 tinned-copper duplex cable built for saltwater, automotive and RV power runs that needs flexible, corrosion-resistant performance.

This 50-foot spool of CONEPY 12 AWG marine wire combines fine-stranded, oxygen-free tinned copper with a thick PVC jacket to deliver reliable conductivity and long-term durability in demanding environments. It meets marine and industry standards for electrical safety and is rated for a wide temperature range, making it suitable for onboard wiring, trailers, vans, solar systems and low-voltage installations up to 600V.

How does this wire stand up to saltwater and sunlight?

The CONEPY cable uses tinned copper strands to resist corrosion and a heavy-duty PVC jacket formulated to repel UV damage, abrasion and salt spray. These layers work together to prolong service life and reduce maintenance compared with untreated copper or standard jacketed wire.

• Tinned, oxygen-free copper resists electrochemical corrosion in marine environments
• Thick PVC jacket protects against UV, abrasion and saltwater exposure
• IP68 waterproofing for enhanced moisture resistance
• Temperature-rated -40°F to 221°F for varied climates

Will this cable handle common boat and RV electrical loads?

Yes — each conductor is 12 AWG (3.32 mm²) made of 47 strands of 0.3 mm tinned copper, giving it higher conductivity and current capacity than comparable aluminum wire. The cable is suitable for 5V, 12V and 24V systems and can be used safely in applications within the rated 600V limit.

• 12 AWG cross-section (3.32 mm²) for efficient power transfer
• 47-strand construction increases flexibility and current capacity
• Compatible with LEDs, lights, speakers, inverters and more
• UL 1426, SAE and ABYC compliance for marine-grade installations

How easy is the wire to work with during installation?

The multi-stranded tinned construction keeps the cable flexible at bends and through bulkhead chases while the duplex format (12/2) simplifies runs by bundling the positive and negative conductors. Its robust jacket is still stripable with standard tools, and the spool length minimizes joins on a moderate-sized vessel or vehicle.

• Flexible 47-strand conductors ease routing and connection
• Duplex 12/2 pairs positive and negative conductors together
• 50-foot length reduces need for splices in many installations
• Works with common connectors and marine terminals

What safety and performance specs should I know before buying?

CONEPY marine wire carries multiple industry ratings: VW-1 flame retardant, IP68 waterproof protection and compatibility with ABYC, SAE and UL 1426 standards. The cable’s operating range and voltage rating make it suitable for most low-voltage onboard and vehicle applications when installed per code and best practices.

• Rated voltage up to 600V; suitable for 5V/12V/24V systems
• Flame retardant rating VW-1 and IP68 waterproof rating
• Operating temperature -40°F to 221°F for climate resilience
• Designed to meet ABYC, SAE and UL 1426 guidance

Who is this for: The CONEPY 12 Gauge Marine Wire 50FT is aimed at boat owners, RV and van converters, trailer builders and DIYers who need a flexible, corrosion-resistant 12/2 cable for power runs, lighting, speakers and low-voltage systems. Choose this cable if you want a marine-grade, easy-to-route wire that supports long-term reliability in wet, hot or UV-exposed installations without sacrificing conductivity.
