A breaker for an AC unit should be sized according to the maximum current the unit will draw. The breaker should be rated for at least that amount of current.
How To Size Breaker For Ac Unit
The size of an air conditioner breaker is determined by the maximum current draw of the unit. Most air conditioners have a current draw of between 10 and 15 amps. The breaker size should be equal to or greater than the unit’s current draw. For example, if the air conditioner has a current draw of 12 amps, the breaker size should be 20 amps or greater.
