Wire Sizing Calculator Wire Size Calculator – EXPLORIST.lifeΔThis calculator does NOT supersede manufacturers’ recommendations. Always read and follow the manufacturer’s recommended wire and fuse sizes when provided. This calculator is set up to be used with high-quality stranded wire with a 105 degree C temperature rating only. This calculator is for DC circuits only and is NOT to be used to size 120V or 240V AC circuits.Amps Amps After Derating Voltage Length Is this wire installed in an engine compartment?
