Ancor #10 Black 25' Spool Tinned Copper

The Ancor #10 Black 25' Spool Tinned Copper wire is the backbone of reliable marine electrical installations and repairs. Whether you're running a new console, replacing corroded wiring in engine compartments, or upgrading your boat's electrical backbone, this tinned copper conductor is engineered for saltwater environments where standard copper fails. Marine electricians and serious boaters choose Ancor because it resists corrosion and maintains conductivity where conditions demand absolute dependability.

The #10 gauge tinned copper construction delivers low resistance and superior current-carrying capacity for high-draw circuits—navigation lights, bilge pumps, battery banks, and auxiliary systems. Tinning (the thin layer of solder coating the copper strands) acts as a barrier against oxidation and saltwater corrosion, preventing the green patina that degrades traditional copper wire and causes voltage drop over time. The 25-foot spool format is ideal for custom lengths and test installations, eliminating waste and keeping spares organized in your engine room or tackle locker.

Anglers and cruising boaters rely on Ancor tinned copper for systems that won't fail mid-water—GPS plotters, fish finders, trim tabs, and thruster controls all demand this level of reliability. The black insulation simplifies identification and blends seamlessly into cabin and console layouts. Use this wire for any 12V or 24V marine DC circuit rated up to the amperage your #10 conductor supports; pair it with proper marine-grade connectors and heat-shrink tubing to ensure waterproof joints that last.
