Ancor Red 4 AWG Tinned Battery Cable 50-Foot

The Ancor Red 4 AWG Tinned Battery Cable is a 50-foot length with Type 3 ultra-flexible construction, rated 600V.

Fifty feet of 4 AWG covers a single positive run, against the 100-foot spool for a boat with several circuits at this gauge. Alternator circuits are specifically worth mentioning here, since an upgraded alternator often needs heavier cable than the engine came with.

Making that upgrade without also reviewing the protection leaves the new cable able to deliver more fault current than the old fuse was chosen to clear. The cable and its protection are one decision rather than two.

Tinned copper stranding resists corrosion and electrolysis where moisture and salt reach the conductor. Ultra-flexible Type 3 construction routes through battery compartments and machinery spaces while withstanding vibration, with premium vinyl insulation staying flexible in extreme cold.
