Ancor Black 12 AWG Tinned Copper Wire 250-Foot

The Ancor Black 12 AWG Tinned Copper Wire is a 250-foot spool of single conductor with Type 3 ultra-flexible stranding.

Twelve gauge single conductor is the size most boat DC circuits use, and single conductor is how most of them are actually run. Positives fan out individually from a panel while negatives collect at a bus, so buying duplex for every circuit means burying half of each cable unused.

Two hundred and fifty feet suits adding circuits or refitting an area rather than rewiring a boat. Black is the traditional negative color, with yellow stocked in the same gauge and length for boats following ABYC convention.

Tinned copper stranding protects against corrosion and electrolysis in damp and saltwater conditions. Ultra-flexible Type 3 construction routes through panels, consoles and machinery spaces while resisting vibration and repeated flexing, with insulation staying flexible in extreme cold.
