Ancor 6/2 250ft Spool Bonded Tinned Copper Duplex Black/Red

The Ancor 6/2 250ft Spool Bonded Tinned Copper Duplex Black/Red marine electrical cable is the professional-grade wiring solution trusted by serious boaters, commercial fishermen, and marine electricians for permanent onboard installations. This duplex configuration delivers two independent 6 AWG conductors in a single jacket, eliminating the need for separate cable runs and simplifying routing through tight engine compartments and console panels. Whether you're upgrading a fishing vessel's power distribution, installing a new battery bank, or running heavy-load circuits from alternator to battery or battery to thruster, this 250-foot spool provides enough capacity to handle projects across center consoles, cruisers, and sportfishing boats without mid-project splices.

Ancor's bonded tinned copper construction resists corrosion in salt and freshwater environments—critical for boats where standard copper wire oxidizes and fails prematurely. The tinning process coats each copper strand, preventing green verdigris buildup and maintaining conductivity year-round, especially vital in engine rooms and through-hull applications where condensation and spray are relentless. The duplex design means the two 6 AWG conductors share a single UV-resistant polyethylene jacket, reducing installation labor while maintaining the voltage-drop characteristics needed for high-amperage circuits like 200+ amp main feeds or dedicated thruster power. At 70.65 pounds, the full 250-foot spool balances weight and capacity for both boat shops and technicians who value having sufficient stock without excessive handling.

Serious anglers and vessel operators rely on Ancor duplex cable for battery-to-engine systems, auxiliary power circuits, and shore-power backbone runs where reliability cannot be compromised. The black and red conductor color-coding follows standard marine positive/negative convention, eliminating guesswork during installation and future service calls. This spool is ideal for repairing aging wiring, upgrading undersized circuits that cause voltage drop on electronics, or building out a secondary battery system for tournament fishing or extended offshore runs—applications where mid-journey electrical failure is unacceptable.
