Ancor Yellow 4 AWG Battery Cable Spool, 100-Foot

The Ancor Yellow 4 AWG Battery Cable is a 100-foot spool with Type 3 ultra-flexible construction, rated 600V.

Yellow marks this as a DC negative under ABYC convention, the alternative to black in the same gauge. Four gauge is where the convention starts to matter, since these circuits carry enough current that a wrongly identified conductor is a real problem rather than a puzzle.

A hundred feet suits a windlass or thruster return, or two or three shorter negative runs. Pairing it with the red 4 AWG in the same length covers a complete circuit from one order.

Tinned copper stranding protects against corrosion and electrolysis where salt and moisture reach the conductor. Ultra-flexible Type 3 construction routes through battery compartments and machinery spaces while resisting vibration fatigue, with insulation rated 105°C dry and 75°C wet.
