Ancor #4 Red 100' Spool Tinned Cooper

The Ancor #4 Red 100' Spool Tinned Copper battery cable is the marine electrician's standard for reliable DC power distribution on boats of all sizes. Built to withstand the corrosive salt-air environment and constant electrical demand of modern vessels, this heavy-gauge tinned copper wire delivers the low-resistance performance your boat's electrical system demands. Whether you're wiring a new 24V trolling motor circuit, upgrading shore power connections, or rebuilding a battery bank from scratch, this spool provides the quality cable that serious boaters and professional installers trust.

Constructed with tinned copper conductors and exceeding UL 1426, ABYC (American Boat and Yacht Council), and U.S. Coast Guard Charter Boat standards, the Ancor #4 Red 100' Spool offers marine-grade durability that standard automotive cable cannot match. The #4 AWG (19mm) gauge provides optimal current-carrying capacity for high-load applications while maintaining flexibility for routing through tight engine compartments and bulkheads. Tinning prevents oxidation and corrosion that would otherwise degrade conductivity over time, a critical advantage in saltwater and brackish environments where bare copper fails rapidly. The 100-foot spool length covers most complete rewiring jobs without excessive waste.

This cable is ideal for battery-to-engine starter circuits, main DC feeders, and any primary power run where voltage drop and safety are non-negotiable. The red insulation convention clearly marks positive polarity, reducing installation errors and simplifying future troubleshooting. Install terminals using proper crimping tools and heat-shrink tubing rated for marine service, and your electrical foundation will outlast the vessel itself. At 18.6 lbs per spool, the weight reflects genuine copper content—never aluminum or other inferior substitutes that fail under load or in harsh conditions.
