Ancor Black 3/0 AWG Tinned Battery Cable 50-Foot

The Ancor Black 3/0 AWG Tinned Battery Cable is a 50-foot length with Type 3 ultra-flexible stranding, rated 600V.

Three aught is the heaviest gauge in this range, for very high-current circuits: large battery banks, high-output inverters and heavy charging systems. At that size the cable is expensive enough that measuring the run properly first matters. A 50-foot length is what most single installations actually need rather than a bulk roll.

Ultra-flexible Type 3 stranding is what makes 3/0 routable at all, since a coarser-stranded cable this size barely bends. That flexibility is the difference between a cable that follows the run and one that fights every turn through a machinery space.

The tinned copper conductor protects against corrosion and electrolysis in damp, salty and vibration-prone conditions. Premium vinyl insulation stays flexible in extreme cold, and Ancor states the cable exceeds UL 1426, ABYC and applicable US Coast Guard charter-boat standards. Explore more battery cable.
