Ancor 14/2 100' Spool Tinned Copper Duplex

The Ancor 14/2 100' Spool Tinned Copper Duplex marine-grade electrical cable is built for serious boaters and marine electricians who demand reliability in demanding saltwater and freshwater environments. This dual-conductor wire serves as the backbone for everything from cabin lighting and navigation systems to bilge pump wiring and shore power connections. Whether you're installing new electrical systems, running upgrades, or performing maintenance on a fishing vessel, cruiser, or commercial boat, this 100-foot spool delivers the length needed to complete jobs without excessive splicing or waste.

The 14-gauge tinned copper construction provides superior corrosion resistance compared to bare copper, a critical advantage in the harsh marine environment where salt spray and moisture constantly attack exposed metal. The duplex configuration—two insulated conductors run parallel—simplifies installations by consolidating positive and negative runs into a single, manageable cable that reduces clutter in tight engine compartments and cabin spaces. Tinning protects the copper strands from oxidation while maintaining excellent conductivity and flexibility, ensuring long-term reliability even after years of exposure to UV, temperature cycling, and moisture. The 100-foot spool length (5.55 lbs) makes it practical for mid-sized projects without the weight penalty of larger industrial spools.

This cable is ideal for DC systems on sailboats, fishing boats, and RV-equipped vessels where 14-gauge conductors handle 15–20 amp circuits efficiently. Marine electricians and boat owners frequently specify Ancor tinned copper duplex for cabin wiring, battery jumper cables, and auxiliary system feeds because it meets ABYC (American Boat and Yacht Council) standards for marine electrical safety. Installation is straightforward with standard marine terminals and heat-shrink connectors; the flexibility of the tinned copper allows it to route through tight spaces and around engine components without kinking or cracking.
