## How far can you run 12 gauge wire on a 20 amp circuit?

Originally Answered: How far can you run 12 gauge wire on a 20 amp circuit? You don’t want the voltage drop to exceed 3%, or 3.6 V. A length of 53 feet will cause a voltage drop of 3.6 V. So I would say 50 feet is the max length on a 120 V, 20 A permanent branch circuit.

## Can 12 AWG handle 25 amps?
