Ancor 6/2 100' Spool Tinned Copper Duplex

The Ancor 6/2 100' Spool Tinned Copper Duplex is the workhorse marine electrical cable that serious boaters and marine electricians trust for permanent vessel installations. Whether you're running power to a new console, rewiring a fuel pump circuit, or upgrading your vessel's electrical backbone, this dual-conductor cable delivers the reliability needed in the saltwater and freshwater environment. Built to handle the demands of modern marine systems, it's the standard choice for professional-grade boat wiring where corrosion resistance and long-term durability matter.

This cable features tinned copper conductors—a critical advantage in marine applications where bare copper corrodes rapidly in moisture-rich environments. The tinning process coats each strand with a protective layer of solder, dramatically extending service life and maintaining conductivity even in bilge areas, engine compartments, and exposed deck runs. The 6/2 gauge (two 6 AWG conductors) provides ample amperage capacity for high-draw circuits—think battery banks, thruster systems, or primary distribution panels—while the 100-foot spool length accommodates most mid-size to large vessel projects without splice waste. Duplex configuration means both conductors are bonded together for easier routing and installation.

This cable is essential for any boater tackling electrical upgrades or maintenance who refuses to compromise on materials. Marine electricians and restoration shops specify Ancor tinned copper duplex for everything from new-build wiring to legacy system retrofits, knowing it won't degrade in bilge spray or develop hidden corrosion inside insulation. The 100-foot spool is ideal for single-run projects or as stock for marine shops that service multiple vessels. Installation is straightforward with standard UL-listed marine terminals and breakers; always verify your circuit amperage rating against the 6 AWG current-carrying capacity for your specific voltage and run length to ensure safe operation.
