This new requirement is not voltage specific. Dishwasher 120v 15a electric range 240v 50a the microwave requires yet another 120 volt 20 amp circuit but this circuit can be shared with another appliance such as a gas stove. What is the reason for gfci here. Current code suggests a dedicated line run to the breaker box for use with the dishwasher.
