Does a microwave need its own breaker?

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.

What type of breaker do I need for a microwave?

The microwaves require a 120 volt, individual, properly grounded branch circuit with a 3 prong grounding type receptacle protected by a 15 or 20 amp circuit breaker or time-delay fuse. Over-the-Range microwave models should always be on a dedicated circuit.

What appliances need their own breaker?

Appliances drawing enough power to require their own circuit include ovens, stoves, dryers, washing machines, dishwashers and hot tubs. Some garbage disposals, space heaters, microwaves, refrigerators, freezers and garbage disposals also might require enough wattage to demand separate circuits.

Can a microwave be on a 15 amp breaker?

Larger 1000-1100 watt microwaves absolutely require a 20 Amp breaker for safe and optimal use. Though a 15 Amp circuit is generally sufficient for lower-wattage (600-700 watt) microwave ovens, a 20 Amp circuit is still the recommended size for safe and reliable use.

Can I share a microwave outlet?

And it's good to note that they've changed since the early days of microwaves. According to the 2020 version of the NEC, you can't power a microwave and refrigerator on the same circuit because each of these appliances requires a dedicated circuit, which is one shared by no other appliances or lights.

Root Electric FAQ - Microwave Tripping The Circuit Breaker

Is it OK to plug a microwave into an extension cord?

We strongly recommend that an extension cord not be used with a microwave due to potential safety hazards under certain conditions. Your microwave should be plugged into its own properly grounded, dedicated electrical outlet to prevent the flickering of the lights, blowing of a fuse or tripping of a circuit breaker.

Does a microwave need a GFCI?

Moderator. IMO, the '17 Code clarified this situation. In 210.8(A) GFCI is required for kitchen receptacles that are installed to serve the counter-top surfaces.

Does a microwave need a 15 or 20-amp outlet?

Microwaves require a 20-amp branch circuit due to constant load and spike issues. Under strenuous use, a microwave could draw nearly the maximum 15 amperes of current regularly for hours. Under this maximum load scenario, 14- gauge wiring could heat up beyond safe levels.

Why is my microwave tripping the breaker?

The answer: The microwave is overloading the electrical circuit. In other words, the circuit is rated to handle a certain amount of amps (unit of electrical current), and the microwave is exceeding that amount, causing the breaker to trip.

How many amps is a 1200 watt microwave?

But, keep in mind that a 1200 Watt microwave use 10 Amps @120 volts. In order to power such microwave at full power, 2000 watts power inverter combined with a deep-cycle battery is recommended.

Can microwave and dishwasher be on same circuit?

Dishwashers, disposals, and microwaves all tend to be power-hungry beasts, meaning that you're going to have a hard time fitting even two of the three on the same branch circuit, and putting all three together on a single circuit is a non-starter.

Should a refrigerator be on its own breaker?

Having the refrigerator on its own dedicated circuit is the recommended best practice for homeowners. Most refrigerators run between 3 to 6 amps, with that said, a refrigerator can spike at peak usage up to 15 amps.

Why is there a need to separate some appliances in a circuit and place them in their own circuits?

The reason that certain appliances require their own dedicated electrical circuit is that their electrical draw is significant enough that it is safest to not have any other appliances drawing power through that wiring or breaker switch.

What size breaker do I need for a 700 watt microwave?

Microwaves require either a 15 amp breaker or a 20-amp breaker, depending on their wattage requirements. Microwaves that use 600 to 700 watts can get by with a 15-amp breaker, but microwaves that use over 700 watts should have a 20-amp breaker.

How many amps does a microwave pull?

The microwave ovens consume power at a rate of 650– 1200 watt, which equates to a current of around 10 Amps.

Can I use any 20 amp fuse for my microwave?

Generally with fuses as long as you replace it with a fuse having the same rating it is OK to do so. Although ceramic fuses do offer better thermal and arc protection than glass fuses which is why they're used in microwave ovens and other high current appliances.

Can an old microwave trip a breaker?

Microwaves pull a lot of electricity from your circuit, and so a microwave might trip your circuit breaker due to overloading the circuit. However, it could also be tripping your breaker if the microwave is faulty, or you have an electric issue.

Can I plug a microwave into a non grounded outlet?

For personal safety, this appliance must be properly grounded. The power cord of this appliance is equipped with a three-prong (grounding) plug which mates with a standard three-prong (grounding) wall receptacle to minimize the possibility of electric shock hazard from this appliance.

How many amps is a 900 watt microwave?

According to the manufacturer this unit uses about 900W, 110V and draws 13 amps.

Can a microwave be on small appliance circuit?

A portable trash compactor, dishwasher and microwave are legal to plug in to the small appliance circuits.

Should a refrigerator be plugged into a GFCI outlet?

Residential Kitchen

In a dwelling unit (residential), GFCI protection is only required for kitchen receptacles that serve the countertop surfaces. There's no requirement to GFCI protect receptacles that serve a refrigerator. Unless the fridge is plugged into a countertop receptacle.

Is a microwave 110 or 220?

The majority of microwaves operate on 220 volts.
