Does A Microwave Need A Dedicated Circuit

Microwaves may be the most useful for quick meals on long days. However, because of its significance, every home requires it. So, you may want to replace your old one, purchase one for the first time, or relocate to a new home and wonder does a microwave need a dedicated circuit.

A microwave, on the other hand, necessitates its own circuit. When using the microwave, a dedicated circuit is required to provide continuous power. Because there would be no appliances to drag for energy, it would provide just the right amount of energy required to make the microwave function properly. 

Dedicated microwave circuits should have a current of 20 amps flowing through it. All of your kitchen appliances must have enough power outlets in your home. In this article, we’ll look at why you should have a microwave breaker and how to make sure your home is ready for all of your cooking needs.

Does A Microwave Need A Dedicated Circuit?

Electrical appliances such as ovens, refrigerators, air conditioners, washing machines, and dryers all operate on alternating currents (AC). When using these devices, make sure they don’t overload the circuit. Microwaves are subject to the same rule. So, does a microwave require its own circuit?

Microwaves come in a variety of shapes and sizes, and each model has its own set of requirements. As a result, some models — countertop models, over-the-range or built-in models, above the stove — require their own circuit. Keep in mind that larger ovens require separate circuits as well. It varies depending on the model’s maximum wattage.

However, having a separate circuit is not always required. Each circuit has its own circuit breaker. High-wattage appliances require their own electrical board to achieve the desired wattage. As a result, they can run without causing the breaker to trip.

A dedicated circuit is required for a countertop microwave. A dedicated circuit would help provide enough energy for proper operation. Connecting to a dedicated circuit would be much easier as a countertop appliance. This is because the distance between the circuit and the microwave is relatively short. Even so, a dedicated circuit for a countertop microwave is not strictly necessary.

A countertop microwave has the advantage of being able to be connected to a regular outlet rather than a dedicated circuit. However, a dedicated circuit is required. It will assist in maintaining a steady electric flow to the microwave without any interruptions that you may experience when another appliance is sharing it.

A countertop microwave usually draws a lot of power. As a result, it is necessary to connect to an electronic source that provides a high current. When a countertop microwave is connected to a dedicated circuit, the circuit should have a constant power of 20 to 25 amps. This constant current flow will aid in the proper operation of the countertop microwave.

Can You Plug A Microwave Into A Regular Outlet?

Regular outlets are frequently used to connect many other appliances, which can sometimes damage them. As a result, some appliances require a dedicated circuit. So, can you plug a microwave to a regular outlet?

Yes. A microwave can be plugged into a standard outlet. Regular outlets to which a microwave can be connected should have enough electric capacity to allow the microwave to function properly without causing any problems. These problems frequently result in fires or the microwave being damaged. As a result, it’s preferable if the outlet itself allows for consistent electric power flow.

Microwaves typically consume 6.5 amps, 1500 watts, and run on 120 volts. As a result, when using a standard outlet, the amperage should be at least 12.5 amps. This capacity can sustain the microwave and allow it to operate at peak levels without interruption in the microwave’s power supply.

The lack of a breaker that controls the flow of electricity to the microwave is a significant disadvantage of using a regular outlet. As a result, an overflow of current may occur, causing damage to the microwave and, in some cases, causing fires that may cause damage to other appliances.

When using a regular outlet, it is best to use it solely for the microwave to avoid a power outage while the microwave is in use. Standard outlets are frequently shared, which contributes significantly to power shortages.

Sharing adds drag to the power supply, which may cause the microwave to malfunction due to a power shortage. As a result, regular outlets with the appropriate number of ports for the microwave are required.

Most microwaves have three prongs, and these prongs must be properly fitted to the outlet to allow current flow. If they are not done correctly, the microwave will frequently trip. This tripping may cause the microwave to malfunction, and the outlet, as in most cases, may be damaged.

What Is The Purpose Of Dedicated Circuits?

Dedicated circuits usually come with several features. Here, I’ll explain the purpose of dedicated circuits.

They detect the electrical circuits that operate the signal processing functions in microwave frequencies. Amplification, frequency conversion, mixing, filtering, phase shifting, power dividing, and detection are just a few examples.

A dedicated circuit is a circuit that is only used for one purpose. In electric boxes, it comes with its own breaker. It is installed in only one appliance for that purpose, making it “dedicated.” This single circuit’s energy will not be used by any other outlets.

They only allow access to the energy of the specific appliance, making it easier for it to function without overloading the electrical system. A dedicated circuit also has a separate breaker that connects to only one appliance.

Can A Refrigerator And Microwave Be On The Same Circuit?

A lot of people tend to ask if they could connect their refrigerator and microwave to the same circuit.

A refrigerator and a microwave cannot share the same circuit. This is due to the fact that both a refrigerator and a microwave require a large amount of electricity to operate. As a result, connecting them to the same circuit will result in an overload and a break in the current flow. This could result in the refrigerator, microwave, and even circuit damage. From time to time, fire can break out.

Overloading a circuit occurs when two or more appliances that require a lot of power to operate are connected to the same circuit. For example, regardless of the capacity of the circuit, it is not advisable to connect a refrigerator and a microwave to the same circuit. This may cause the breaker to burn, resulting in a complete shutdown of the current flow.

When you have a refrigerator and a microwave, you should connect them to separate dedicated circuits to ensure that they have enough power.

This would avoid a disruption in current flow that could occur if both were connected on the same circuit. Additionally, dedicated circuits for each appliance will aid in controlling current flow and reducing damage.

When a refrigerator and a microwave are connected to the same power source circuit, both may operate very slowly. This is due to insufficient current being supplied to both the microwave and the refrigerator, resulting in slow operation.

And if they operate slowly, you will not achieve the goal of connecting them. Another effect of connecting the refrigerator and microwave is that heat may be produced slowly while working. Heating up could be harmful to both appliances.

The consequences may be that the outlet burns or that vital components of the appliances begin to malfunction.

What Size Breaker Do I Need For A 1000 Watt Microwave?

Are you curious to know the best size for a breaker for a microwave of 1000 watt?

The size of the breaker required for a 1000 watt microwave is 1700 watts of circuit power, which is usually around 14 amps. A microwave, on the other hand, should only require 120 volts of electricity. As a result, using a larger breaker for the microwave will aid in the proper conduct of electricity.

Breakers come in a variety of sizes to fit the right side of the appliance. The larger the appliance, the larger the breaker that must be used. When using a 1000 watt microwave, keep in mind that the breaker size should be large enough so that the microwave can function properly without being damaged.

Due to the microwave’s high current demand, a smaller-sized breaker will trip on a regular basis. This will have an effect on the microwave because the required current may not be available. In this case, the breaker may be burned during the process, and there may be instances of fire outbreaks.

Best Microwaves

  1. Panasonic NN-SN75LB 1.6 cu.ft Cyclonic Inverter Countertop Microwave Oven

This Panasonic microwave is quick due to two factors: It has a heating power of 1,250 watts, one of the highest wattages we tested, and a built-in inverter that helps heat food more quickly and evenly. Microwaves typically simulate low heat by cycling the power on and off repeatedly, which is slower and can result in uneven cooking. Inverters aid in the continuous delivery of power. Microwaves with inverters performed well in our tests for evenly reheating food and baking potatoes, but they couldn’t defrost ground beef as well as regular microwaves.

This model includes a smart sensor that detects the amount of steam released by the food and adjusts both the power level and the cooking time for the best results. Ita “quick 30” button, more and less buttons for adjusting cooking times in 10-second increments, a quick-minute timer, a delay-start feature, and a child safety lock. We like the keep warm feature, which can be enabled at the start of the cook cycle and will run for up to 30 minutes after the cook cycle is completed. The sensor cook button has 14 presets for everything from oatmeal to fish fillets, but keep your owner’s manual handy because that’s a lot of codes to remember.


  • Food is evenly reheated.
  • Cook times can be increased or decreased in 10-second increments.
  • Keep warm function


  • Not the best at defrosting


When using a microwave, a dedicated circuit is not required, but it must be kept operational. A dedicated circuit also reduces electricity drainage, which frequently affects current flow to the microwave.

The consequences could be complications that damage the microwave. This article discusses the benefits of using dedicated microwave circuits.
