Exactly. The breaker trips because the oven is getting damaged by arcing. This is correct behavior. Running microwave underloaded is incorrect behavior.
Why does my microwave keep tripping the arc fault breaker?
Electrical Overload
Like any other breaker, an arc circuit breaker can trip if there’s too much electrical usage on a single circuit and it overheats the wires. Perhaps you plugged in a power tool on the same circuit with your washer, dryer, and microwave, and it’s too much for the circuit to handle.
Can a microwave be on a AFCI breaker?
The breaker for this dedicated circuit is a Dual Function AFCI/GFCI Circuit Breaker (Siemens, 15 amp). The microwave manual recommends a dedicated 15 amp circuit. The microwave works fine for a few days, then suddenly it starts tripping the breaker within 5 seconds of starting it, no matter what is in it.
How do you stop a microwave from tripping the circuit breaker?
Plug the unit into an alternate outlet, in an area of your home where the breaker has a higher amperage, such as in a garage or workshop, or into an outlet with a guaranteed dedicated circuit. If the appliance trips the breaker, the problem lies with the microwave, and you’ll need to either repair or replace it.
Where are arc fault breakers required 2020?
In the 2020 edition of the NEC®, Section 210.12 requires that for dwelling units, all 120-volt, single-phase, 15- and 20-ampere branch circuits supplying outlets or devices installed in dwelling unit kitchens, family rooms, dining rooms, living rooms, parlors, libraries, dens, bedrooms, sunrooms, recreation rooms, …
Does a microwave need a GFCI breaker?
A GFI or GFCI outlet is needed if the microwave is located less than 6 feet from a water source such as the edge of the sink, toilet, shower, etc. It is also needed if located outdoors, garages, kitchen counter tops, near laundry, utility sinks, wet bar sinks and near swimming pools.

Does a microwave need a dedicated circuit?
Microwave ovens often demand dedicated circuitry, but this isn’t always a necessity. The National Electrical Code requires it for all fixed equipment, so a circuit must be set aside for any built-in oven. Small or older countertop models draw less power than modern full-size units.
Can an AFCI replace a GFCI?
Yes, they both can be used on the same circuit; however, the Dual Function AFCI/GFCI Receptacle offers the option of providing both AFCI and GFCI protection in a single device.
Do kitchens require AFCI?
The National Electrical Code (NEC) requires arc fault circuit interrupters (AFCI) and ground fault circuit interrupters (GFCI) for certain electrical circuits in your home, including the kitchen.
Where are AFCI breakers not required?
Exception: AFCI protection shall not be required where the extension of the existing branch circuit conductors is not more than 1.8 m (6 ft) and does not include any additional outlets or devices, other than splicing devices.
Does refrigerator need AFCI?
Refrigerator Circuit
This circuit usually does not require GFCI protection unless the outlet is within 6 feet of a sink or located in a garage or basement, but it generally does require AFCI protection.
What requires AFCI breaker?
AFCI protection is currently required for all 15 and 20 amp branch circuits providing power to outlets* in residential family rooms, dining rooms, living rooms, parlors, libraries, dens, bedrooms, sunrooms, recreation rooms, closets, hallways, and similar rooms or areas.
