Ancor Yellow 8 AWG Tinned Copper Wire 250-Foot

The Ancor Yellow 8 AWG Tinned Copper Wire is a 250-foot spool of single conductor with Type 3 ultra-flexible stranding.

Yellow marks this as a DC negative under ABYC convention, distinguishing it from the black version of the same gauge. On a boat with AC wiring aboard, that distinction is the whole reason the convention exists, since black appears on the AC side too.

Eight gauge negatives are typically shorter than the matching positives, since they run to a common bus rather than out to individual loads. That means a boat rarely needs equal footage of each color, and buying separate spools rather than duplex reflects how the wiring actually runs.

Tinned copper stranding gives added protection against corrosion and electrolysis in wet environments. Ultra-flexible Type 3 construction routes around equipment and through electrical compartments while resisting flexing fatigue, with insulation staying flexible in extreme cold.
