Because most microwaves pull about 12 amps, they need their own dedicated circuit. This means they shouldn’t share a circuit with any other appliances, or they’ll quickly overload the circuit and trip the breaker. To check to see if your microwave is on a dedicated circuit, look at the label on the tripped breaker.

Do microwave ovens have fuses?

Microwaves usually contain several types of fuses for safe operation. A main fuse or line fuse is a fuse that will cut the flow of electricity if too much current passes through it. Conversely, a thermal fuse will prevent electrical flow if the fuse is heated to a specific temperature.
