Yes, the NEC allows you to put a kitchen microwave on a 15-amp circuit breaker under the following conditions



Manufacturer's Approval

The manufacturer of the microwave must specifically approve the use of a 15-amp circuit breaker. Check the appliance's installation instructions or contact the manufacturer for confirmation.

Minimum Circuit Capacity

The microwave's maximum amperage draw must not exceed 80% of the circuit breaker's rating. For a 15-amp circuit breaker, this means the microwave's maximum amperage draw should not exceed 12 amps (80% of 15).

Dedicated Circuit

The microwave must be on a dedicated circuit, meaning it is the only appliance connected to that circuit. This prevents overloading the circuit.

Proper Wire Gauge

The wire used for the circuit must be at least 14 AWG (American Wire Gauge) copper or aluminum.

Additional Considerations



Other Appliances on the Circuit

If the circuit powers other appliances besides the microwave, it's important to factor in their amperage draw to ensure the total load does not exceed the circuit breaker's rating.

Circuit Protection

The circuit should be protected by a Ground Fault Circuit Interrupter (GFCI) or an Arc Fault Circuit Interrupter (AFCI). This provides additional protection against electrical hazards.*

Consultation with a Qualified Electrician: It's highly recommended to consult with a qualified electrician to ensure that the installation meets all electrical codes and safety standards. Flag for review
