Do microwaves need this GFCI? Depending on its proximity to water sources such as a wet counter, kitchen sink, shower, or even swimming pools, a microwave should be plugged into a GFCI outlet.

Electric shocks are standard when uncontrolled electrical appliances come into contact with these locations. As a result, a microwave should be plugged into a GFCI outlet before being utilized in any of these situations.

We also use microwaves outside, and a GFCI outlet must be utilized if the microwave is used within six feet of laundry, utility sinks, or garages.

Although some microwaves are used in areas far from water sources and moist locations, it is strongly recommended that they be plugged into a GFCI outlet, which serves as a dedicated circuit that protects both the microwave and the user from electrical power surges.

Do Microwaves Require GFCI

Do Microwaves Require GFCI?

Microwaves do require GFCI. Regardless, the size of the GFCI needed is determined by the position of the microwave.

The use of a ground fault circuit interrupter (GFCI) decreases the risk of severe electric shock or electrocution in certain fatal circumstances. Microwaves should be used with GFCI to be on the safe side.

What Does Gfci Do?

It sure is a good idea to use a GFCI outlet in a place where there is a slight chance of any mishap happening. So, you should always use a GFCI outlet if your electrical outlet is near water. 

Gfci should be adjusted with the electrical outlet. It helps to continuously trace the current flow to detect if any imbalance is happening. Gfci has three holes in it; two of them are for hot cable and neutral; the last hole, which is situated in the middle, works as ground cable. This GFCI outlet works as a detecting tool because if it finds any disturbance in electrical flow, then it will right away break the flow of the current. 

In this scenario, imagine using a microwave which is too close to the water and by mistake you fell a bowl of water in the outlet. Then the GFCI will identify the disturbance and will break the electricity flow instantly to secure your safety. 

What are the reasons behind using GFCI for a microwave?  

There are many reasons to be found to choose an outlet for microwaves. The main reason behind selecting a GFCI outlet for a microwave would be it decreases the possibility of acute or deathly electric shock. So, if you are still thinking that will you need a GFCI outlet for your microwave, then look down below to find your answers-

  • Depends on the placement: You need to select the outlet and be decided by its location because you will only need a GFCI outlet if the electric cables are close to the water—for example, wet kitchen countertop, garage, near swimming pool, close by the laundry, etc. So, you will need it if the microwave is within 6 feet of the water. 
  • No expectation: Use a GFCI outlet for a microwave if it is used too frequently. Suppose the microwave is kept in a public place, for example, a restaurant, commercial area, hotels, etc. 
  • Microwave size: If you have a large microwave in your house, then keep in your mind that it has more risk than the smaller microwaves. Because it has a higher risk for unfortunate electrical incidents, the larger microwaves work more than the smaller ones. In this case, if you choose a GFCI outlet, then you can easily avoid such accidents. 

 What Are The Advantages Of Using Gfci?

If you own microwave in your house and connect it to a GFCI outlet. But you don’t know what is it for or how is it helping you, then let me tell you its benefits-

If your microwave cable comes in contact with water or supposes the cables are damaged, then there is a chance of getting shocked. But if the microwave is connected with a GFCI outlet, this mishap won’t happen.

Again, if the cable gets damaged and leaks spark due to overheating, then it has a possibility to catch fire. So, before the cable catches fire, the GFCI outlet will break the electricity flow to avoid catching fire.

Also, GFCI outlets are known as monitoring devices as well. Because it will identify any changes happening in the current flow by its built-in sensor, it can detect the changes even if it is in milliamps. So, before any further damage, GFCI will cut off the eclectic flow and save you from any risk.

Is It Possible To Plug A Microwave Into Any Electrical Outlet?

Yes, we can get a microwave to function by plugging it into a standard appliance outlet. However, for a microwave to operate securely, it must be connected to a separate circuit.

Large microwaves require a lot of electrical power to work correctly, so we’ll need a fixed outlet with a dedicated circuit that can readily give the power these microwaves require.

On the other hand, smaller microwaves can be plugged into a standard wall outlet, but only if the microwave is kept away from water and damp surfaces.

What Type of Outlet Does a Microwave Require?

Any outlet that decreases the risk of moderate and fatal electric shocks will suffice for a microwave. Because this is a GFCI’s most crucial feature, it is highly recommended for microwave safety.

Regardless, when choosing an electrical outlet for a microwave, we need to consider a few variables such as the location of use, the size of the microwave, safety, and whether the microwave will be used professionally or in a home setting.

1. Useful Location:

Consider where you’ll be using the microwave. After that has been identified, choose the outlet that meets the requirements for proper operation in that type of place.

A GFCI outlet is required for a microwave operated near water or on a nearly always damp surface, such as a wet bar sink or kitchen countertop. A previously used microwave in a different location can also be utilized in another outlet.

2. Microwave Dimensions

Because large microwaves do more jobs than smaller microwaves, they have a more considerable risk of electrical accidents. Choose an electrical outlet with a dedicated circuit that regulates and supplies appropriate electric power to the microwave to avoid this.

On the other hand, smaller microwaves require less electricity to operate and may be plugged into any standard electrical outlet.

3. Security Level

When it comes to choosing an outlet for our microwaves, the ideal option is to go with one that has the best safety features and capabilities. Some outlets are designed to keep users safe by preventing electrical fires, shocks, and electrocution.

Because of its capacity to avoid electric shocks, GFCI outlets are usually put in areas vulnerable to dampness and water, such as bathrooms and kitchens. A GFCI outlet is a viable and safe option for a microwave.

4. For use in a business or at home,

There are outlets available to satisfy the needs of any microwave used to serve many people or for commercial purposes. Likewise, certain outlets have been created specifically for microwaves solely used at home.

The outlets utilized in these two configurations are not interchangeable and should not be used interchangeably. When picking an outlet, it’s crucial to consider whether you’ll be using your microwave for business or home reasons.

What Causes the GFCI to Trip in My Microwave?

When a microwave trips a GFCI outlet, it simply implies the circuit is overloaded. When a microwave is plugged into an overloaded course, it affects efficiency by turning quick and straightforward operations into challenging, tedious, and time-consuming labor. This is because the circuit can no longer produce the power required by the microwave.

An overloaded circuit can be caused by various factors, including too many appliances plugged into the same circuit as the microwave, a broken GFCI, or a faulty microwave.

1. There are too many appliances on a single circuit:

Microwaves consume a lot of power from a circuit, but when other appliances are on the same course, the demand exceeds what the circuit can manage, and the circuit trips.

When this happens regularly, the circuit may fail, causing damage to all the appliances that rely on it. Extreme circuit tripping can heat the house’s wiring and trigger electrical fires.

This is why a separate circuit for each microwave is strongly recommended, as a dedicated circuit only powers one device and nothing else.

2. Fault of GFCI:

If your microwave is connected to a dedicated circuit but still trips the GFCI, the outlet may not be adjusted appropriately. If the GFCI outlet continues to stumble after reset, the course has a defect.

If you connect the microwave into another outlet and it works fine without tripping the GFCI, you have a malfunctioning GFCI.

To find the source of the issue, an electrician should test the GFCI outlet appropriately.

3. Fault of Microwave:

A GFCI outlet can be tripped by a microwave merely because it has developed a fault.

Connect the microwave to a dedicated circuit and another outlet to test this. If it keeps tripping, the issue is most likely with the microwave.

Because this is harmful to an inexperienced user, a qualified technician should look for and repair the cause of the defect in the microwave.

Because the microwave may be defective due to age or low cost, replacing it with a new and better model is better than repairing it.

Is it necessary for an over-the-range microwave to have its circuit?

Circuit for Microwave Oven A dedicated 20-amp, 120/125-volt course is required to power the microwave oven. Microwave ovens can be plugged into regular appliance outlets, but larger microwave ovens, which can take up to 1500 watts, require dedicated circuits.

Should the freezer be GFCI-compliant?

The “protector outlet” you’re referring to is a GFCI receptacle, which is required by construction code in garages, kitchens, bathrooms, and on the exterior of new residences. As a result, GFCIs should never be used to power freezers or refrigerators.

What appliances are GFCI-compliant?

For 125-volt to 250-volt receptacles provided by single-phase branch circuits rated 150 volts or less to the ground, GFCI protection is necessary. Bathrooms, garages, crawl spaces, basements, laundry rooms, and other facilities with a water source must have GFCI receptacles.

Is it possible to hardwire over-the-range microwaves?

While it is possible to wire the new microwave during the installation process, it is not the best solution. The old house had the range fan hardwired without a plug-in for the microwave, and while it is possible to wire the new microwave during the installation process, it is not the best solution. In such circumstances, the range fan’s electricity is fed through the wall behind the fan, into the fan, and connected.

 Is it possible to put a microwave into a standard outlet?

A dedicated 20-amp, 120/125-volt circuit is required to power the microwave oven. Microwave ovens can be plugged into regular appliance outlets, but larger microwave ovens, which can take up to 1500 watts, require dedicated circuits.


It performs best when a microwave is plugged into a dedicated circuit and a safe outlet, such as a GFCI outlet.

The microwave will last longer this way without placing the user at risk of electrical shock. To minimize avoidable failures, it’s also a good idea to avoid sharing a circuit with a microwave and other equipment.
