A standard household microwave typically requires a dedicated circuit with a 15-amp or 20-amp rating, depending on the specific model and its power requirements. The manufacturer's specifications for the microwave will typically indicate the appropriate circuit amperage.
For smaller microwaves with lower power ratings, a 15-amp circuit is usually sufficient. However, larger microwaves or those with higher wattage might require a 20-amp circuit to handle the increased power demand.
To ensure safe and proper operation, it's always recommended to follow the manufacturer's instructions and consult with a qualified electrician or professional for accurate information regarding the electrical requirements of your specific microwave model.
