Ancor Standard Duplex Cable - Flat 12/2 AWG - 2 x 3mm² Red/Black - 500'

The Ancor Standard Duplex Cable in 12/2 AWG with red and black conductors is the go-to choice for boat builders, marine electricians, and serious boaters who demand reliability below deck. This 500-foot spool of flat duplex cable handles the core electrical runs in your vessel—from battery banks to distribution panels, through-hull systems, and DC appliance circuits. Built to marine-grade standards, this cable exceeds UL 1426 and ABYC specifications, meaning it meets the same rigorous certifications required by US Coast Guard charter vessels, so you're investing in wiring that performs in salt spray, vibration, and the demanding environment of saltwater and freshwater operation.

Ancor's premium vinyl insulation and copper conductors rated at 3mm² (12 AWG) per conductor deliver the current capacity and voltage drop performance your boat's electrical system requires without compromising safety margins. The flat duplex configuration—two conductors bonded side-by-side—makes routing cleaner than round cable, fitting more easily through tight spaces in engine rooms, bilges, and behind cabin walls. The red and black color coding follows standard marine practice: red for positive, black for negative or ground, eliminating confusion during installation and future troubleshooting. At 38 pounds per 500-foot spool, the cable handles typical gauge stiffness while remaining manageable for on-site pulling and termination.

Anglers and cruising boaters upgrading batteries, installing auxiliary systems, or rewiring aging vessels will appreciate the extensive coverage a 500-foot run provides—eliminating splices over long runs and reducing voltage drop in critical circuits. The 12/2 AWG size suits 12V and 24V DC systems found in fishing boats, cruisers, and trawlers, making it ideal for connecting house banks, starting systems, and distribution panels. Proper termination with marine-grade lugs and connectors ensures corrosion resistance; always follow ABYC guidelines for sizing, installation, and bonding to maximize system integrity and safety on the water.
