A microwave oven's amp draw can vary depending on its wattage and power requirements. Generally, a residential microwave oven can draw between 9 and 15 amps. For example, a 1,200-watt microwave would draw approximately 10 amps on a 120-volt circuit (1,200 watts / 120 volts = 10 amps). Always check the appliance's specifications for accurate amp draw information. For professional assistance with circuit repairs, the Electricians Service Team is ready to help.
