So, you must ensure that the main breaker size is either the same or higher than the sub-panel breaker.Īs I said, you need to calculate the appliance’s wattage and the number of amps.įor example, a basic load is 30 watts per square meter. The sub-panel will feed from the main breaker.
It means your house should have at least a 200 amp main breaker panel with a 120-volt single phase to power your house.
