How many amps does a microwave use?

Did you know How many amps does a microwave use? Depending on the wattage of your microwave, it will require a different number of amps.

This blog post will provide you with information on how many amps microwaves use so you can be sure to select one that is compatible with your home’s electrical system. Additionally, we will provide some tips on saving energy when using your microwave oven.


What is an amp?

An amp is a unit used to measure the strength of an electric current. One amp equals 1 coulomb per second. Larger currents are measured in kiloamps (kA) or mega amps (MA).

For example, a 100 amp electrical panel would be rated to supply power for 100 amps of current safely. Generally speaking, an appliance will use more than one amp when it is turned on.

How many amps does a microwave use?

Microwaves differ in the number of amps they use, depending on their wattage. The average microwave uses between 1.5 and 2 amps, but some can use four amps or more. To determine how many amps your appliance needs, you must know its wattage. Following are some example microwaves with their corresponding wattages:

Wattage Range in Watts Number of Amps Used

  • 1000-1499 1 – 1.4 2
  • 1500-1999 1.5 – 2 2
  • 2000-2499 2 – 3 3
  • Watt = Amps x 120 (Watts equals volts x amps) So, to determine the number of amps your microwave needs, you’ll need to multiply its wattage by 120. For example, if your microwave is 1500 watts:

Amps = 1500 Watts x 120 Amps = 180 (volts x amps) If you have a microwave that uses just over 1 amp, it will most likely be plugged into a 15-amp receptacle (exceptions are stoves and microwaves with exposed heating elements).

A 20-amp receptacle is more than enough for a 2000 watt microwave or less. If your microwave uses more than two amps, you should consult an electrician to determine if it can be plugged into a range receptacle (where the oven and stove plug into).

A standard 15-amp household circuit cannot handle more than three amps without starting to overheat.

What can I do to reduce the time my microwave uses electricity?

Many energy is lost when microwaves cook food, so it takes longer to cook something using a lower power setting on your microwave.

The following tips will help you save some energy: Use kitchen appliances like toaster ovens and slow cookers whenever possible as they typically use less power than your microwave. Do not heat tough foods in the microwave.

They don’t heat evenly, so you’ll have to use more time & energy than if you cooked it in a pan on the stovetop. If you want to cook something challenging in the microwave, consider cutting it into smaller pieces so they will heat through more quickly.

Don’t overcook food when using your microwave oven – most foods need just 1-2 minutes of cooking per side when using a standard wattage setting (refer to your manual for specific directions).

Microwaves are modern kitchen appliances because they cost less, are easy to use, and make meal preparation quick. But since microwaves only use between 0.7 – 1.4 amps of electricity, using them can add up in cost over time.

To help reduce your electric bill and energy usage, keep the tips mentioned above in mind when cooking with your microwave oven.

Why Do I Need To Know The Amperage Of My Microwave?

The average microwave uses between 1.5 and 2 amps, but some can use four amps or more. To determine the number of amps your appliance needs, you must know its wattage.

Watt = Amps x 120 (Watts equals volts x amps) So, to determine the number of amps your microwave needs, multiply its wattage by 120. For example, a standard oven is 1500 watts:

Amps = 1500 Watts x 120 Amps = 180 (volts x amps) If you have a microwave that uses just over 1 amp, it will most likely be plugged into a 15-amp receptacle (exceptions are stoves and microwaves with heating elements). A 20-amp tin is more than enough for a 2000 watt microwave or less.

If your microwave uses more than two amps, you should consult an electrician to determine if it can be plugged into a range receptacle (where the oven and stove plug into). A standard 15-amp household circuit cannot handle more than three amps without starting to overheat.

How To Calculate Microwave Amp Usage (Simple Two-Step Method)?

First, take the total wattage of your oven and divide it by 1000 to get the number of kilowatts (kW). Then divide this number by 1,000 again to convert from kW to kiloamps (kA). *Remember that there are 1,000 watts in a kilowatt.

So if your microwave is 1500 watts: 1500 / 1000 = 1.5 1.5 /1000= 0.0015 kA

Now multiply .0015 by 120 volts to find out how many amps it uses: 0.0015 x 120 = 0.18 amps.

Step 1: Take the total wattage of your microwave and divide it by 120 (number of watts per amp). This will give you how many amps your appliance uses.

Watt = Amps x 120

Step 2: Now that you know the number of amps, check the label on the back or bottom of your oven to see if it can be plugged into a 20-amp receptacle. If so, then great, but if not, you’ll need to consult with an electrician to determine if you can upgrade your current outlet or install a new one altogether.

How does a microwave use amp?

A microwave is a device that uses electromagnetic waves to heat food directly. These electromagnetic waves are formed as alternating currents and force the electric charges inside food molecules to oscillate, resulting in heat production.

With an increasing demand for this kitchen appliance, manufacturers have introduced different types and brands of microwaves with varying power ratings intended for various applications by catering to the needs of consumers.

Microwave ovens use less power than conventional ovens because they cook much faster, but how much electricity do microwaves use? A dishwasher uses about 5 kilowatt-hours (kWh) per normal cycle, while a standard microwave uses just 1 kWh per hour.

On average, it takes 2.3 kWh per 100 cupcakes baked in a conventional oven, while cooking the same amount of cakes requires just .13 kWh in a microwave.

What Types Of Microwave Ovens Exist?

Microwaves are usually part of an oven combo unit with a separate broiler, standard oven, or other cooking features. When you’re trying to find the best microwave oven, it’s essential to look at how many cubic feet of interior space it includes, as well as what features are available.

Some microwaves only have crucial functions, which might be enough for your needs, but others come with sensor cooking technology and other helpful options to make food taste better.

Convection Microwave

One of the more exciting features is convection microwaving, which can be useful for baking or broiling. This uses the same technology as a standard microwave oven but adds a fan to circulate hot air throughout the food.

By doing this, you can cut the cooking time in half without having to worry about burning your food since it cooks evenly no matter what setting you’re using. These are usually included in oven combo units that have other cooking elements built-in, so they’re not ideal if you’re looking for something compact and cheap.

Microwave Drawer Ovens

A standard option is a drawer that slides out from your countertop, which can become an oven replacement when there’s no space left over in your oven. These tend to be less expensive since they can use various heating elements depending on the type of food you’re cooking.

For example, a microwave drawer oven that uses a quartz element will cook quickly, while a halogen light unit will give you more precise control over your cooking process.

In addition, some microwaves have separate compartments for heating and thawing, but these are difficult to clean in-between if you make a habit out of using them.

If you want an inexpensive option that combines multiple appliances into one, this is probably your best bet but keep in mind that it can take up more space than necessary when used as an oven replacement.

Solo Microwave

The other option is a traditional solo microwave oven where you press a single button and the internal heating element rest. These are generally more expensive than combining multiple appliances, but they’re much smaller and lighter. This is great for people who want to save money or don’t have much countertop space to spare.

Grill Microwave

Another option is a grill microwave oven with a large surface area for grilling small items of food over the heating element. These are often included in oven combo units but can also be purchased separately.

Some people complain that grills tend to overcook certain types of meat, while others swear by them since they’re perfect for steaks, hamburgers, and other similar foods.

What are the benefits of using a microwave?

Microwaves use far less power than conventional ovens and can cook food much more quickly. In addition, microwaves can also be used to defrost frozen foods and heat them.

Also, the ability of a microwave to heat unevenly makes it particularly useful for certain heating types of irregularly shaped foods, such as those that have an indented middle or those that contain a bone. The overall benefit of using a microwave is that it reduces cooking time, saves energy, and decreases cooking costs.

How Much Faster Are High Watt Microwaves Than Low Watt Microwaves?

There is no absolute answer to this question because it all depends on cooking. However, there are general guidelines that can give an idea of how much faster high-watt microwaves cook certain types of food compared with low-watt microwaves.

For example, a 1200-watt oven cooks about twice as fast as a 600-watt one. In addition, since high-watt microwaves cook more quickly than low-watt ones, less time is required for preheating the appliance before a dish may be placed inside to start cooking.

This means that a large amount of electricity will not be needlessly consumed waiting for the microwave to reach the proper temperature.

How Does Microwave Amperage Affect You?

The amount of electricity (amps) consumed by a microwave is affected by three key factors:

  1. The power rating/wattage of the microwave oven itself;
  2. The type of food being cooked;
  3. The volume or quantity that needs to be heated.

It takes more power (amps) to cook foods that require longer cooking times like roasts, whole turkeys, and baked casseroles than preparing vegetables or other side dishes with shorter cooking times.

Foods containing high amounts of water also take more amps to heat because this allows for faster heating throughout the entire world. For example, it may only take an hour for a small potato to be cooked entirely in a high wattage oven, but it may take two hours in a low wattage oven.

Also, the more food is cooked at once, or the more significant the quantity of food to be heated, the more power is required to achieve satisfactory cooking results. A general rule of thumb is that one cup requires 100 seconds of microwave cooking with an 1100-watt oven while two cups require only 80 seconds.

Therefore, it would make sense to cook multiple servings at once rather than extra heat food that will go to waste if it gets cold before all servings are eaten.

Microwave ovens have significantly reduced cooking times and contribute immensely towards energy savings, especially when compared with conventional stoves and ranges. However, different types of foods may require differing amounts of time to cook properly, which can be affected by wattage levels.

Can I Plug My Microwave Into An Extension Cord?

Microwave ovens themselves do not require a direct electrical connection to a power outlet to be plugged into a wall. There are, however, other appliances that may need to be plugged in due to their limitations.

For example, microwaves with external or internal microwave generating units (MGUs) require more electrical current than the standard 120 volts from an ordinary household outlet.

For these MGUs to work correctly, they must be plugged into a 20 amp dedicated circuit generally located outside of the kitchen area because it requires more power than an ordinary outlet can supply.

In addition, if you have an older home with pre-1960 wiring, there is no guarantee that your outlets and circuits will provide the necessary power that your microwave appliance requires to cook food properly. This may lead to overheating, inadequate cooking results, or even a fire hazard.

By using an extension cord, you are essentially asking for trouble because you are attempting to place more power demands on an outlet than it is capable of handling without creating a dangerous situation.

Therefore, it is essential that you check all appliances and wiring before connecting any type of high wattage appliance like a microwave oven to ensure the safety of yourself and your loved ones.

How Does My Microwave Electrical Usage Compare To Other Kitchen Appliances?

As explained above, microwaves require a much lower level of electrical current than standard ranges and conventional ovens because they only heat food and not the entire oven cavity. For example, it takes approximately four hours to cook a 12-pound turkey in an oven but only about an hour and thirty minutes in a microwave.

The wattage for cooking one twelve-pound turkey may range from as low as 1200 watts (conventional) to as high as 1700 watts ( convection ) or even 2700 watts ( infrared ).

In comparison, most countertop toaster ovens use about 1500 watts, while traditional ranges typically operate at around 4000 to 5000 watts, depending on your setting. A modern electric stove with coil elements operates at 1500 watts if you have just one burner on and around 3000 watts if all burners are on simultaneously.

Taking this example further, an electric oven will generally use about ten times more power than a microwave for the same amount of cooking time. At the same time, your stovetop or range may require thirty to forty times the energy usage of a microwave, depending on how many burners are in use.

It should also be noted that microwaves do not heat your kitchen like conventional methods, which further reduces your total electrical usage.

A side-by-side comparison reveals that microwaves cost only one-third to half as much to operate as an electric stove or toaster oven. This means that it takes approximately 75 seconds for a microwave oven to pay for itself compared to cooking on a traditional stove.

By using your microwave, you reduce the amount of energy required to cook your food by more than half while reaping additional benefits like speed, convenience, and enhanced food quality, which are not available with other cooking methods.

What Should I Do If My Microwave Stops Heating Properly?

When dealing with appliances that rely heavily on electrical currents, it is crucial that you do not repair or adjust them yourself because there are dangerous voltages inside that can cause serious injury if touched. Instead, you should call for professional assistance so they can diagnose the problem and make the necessary repairs.

In addition, this may indicate higher electrical usage due to old or faulty wiring, which could lead to an electrical fire if not checked and replaced.

For appliances like microwaves, the cost of an annual service call is well worth it compared to what would happen if you were injured. In addition, it may be cheaper than having to buy a new appliance which can be as expensive as $500 or more for basic models depending on your manufacturer and model number.

How Many Amps Does a Microwave Oven Draw?

Depending on the manufacturer, a standard microwave oven will draw between 600 and 800 watts or six to eight amps of electrical current. It may take more time to cook your food, but you can still use it while waiting for a lower wattage device like a 200 to a 300-watt appliance, which would cost less than half as much money and energy.

Operating Voltage 120V (US) or 240V (EU)

  • Power Consumption 600 to 800 Watts
  • Operating Frequency 2450 MHz ( US ) or 50 Hz ( EU )
  • Number of Amps 6 to 8 amps for 600-800 watts (~6.4 amps for 1000 w)

Operating Voltage 220 (Europe, Asia)

  • Amps are nine amps for ~1000 watts (~3.7 amps for each element ).
  • The number of Amps 4.5 amps for 600 watts (~11 amps for each component).
  • Amperage 7.2 – 9 amps for 1200 – 1700 watts (~3 – 3.7 amps per element).
  • Amperage 14 – 18 amps for ~2700 watts (~1.8 to 2.8 amps per element).

Importance of Knowing the Microwave Amp Draw

It is vital for any appliance that requires electricity to know how many amps it pulls to choose the appropriate circuit breaker for your home. It is hazardous if you plug too high of a wattage device into a Circuit with too little amperage because the result may be an electrical fire or trip, which can damage your appliance and home.

If you are not sure about your particular circuit breaker, call the support number on the side of your regular electric meter and ask what amps your house needs before plugging anything in.

They will usually give you some information over the phone while instructing you to disconnect power at the main breaker box before proceeding further.

It would help if you also verified that all wiring was done correctly by a licensed electrician trained in the local and national codes to ensure that it is done correctly to prevent any issues with your warranty or personal safety.

Why Do Microwave Ovens Use Twice As Much Power In Europe?

A standard microwave oven will typically consume 600 to 800 watts of power in the US. If you look at an international wattage chart, this would be roughly 220 volts, which Europe uses.

Instead of using a transformer or voltage converter, American companies change the plug from a Type A (US) to Type C, which European appliances use. Depending on how much electrical current you are pulling through your device, it can make a difference, so look for Type E or F if available since they have lower amperage requirements.

How to save energy when using a microwave?

While microwaves are convenient and relatively inexpensive, they can be a significant burden on your electric bill if you use them too often. Instead of using the microwave as a quick way to reheat leftovers or cook something for 5 minutes, try using an oven instead so you can bake or broil whatever it is you need to eat.

In addition, there are simple habits that everyone can follow which will reduce your wattage usage without any impact on your ability to heat food quickly. For example, you should only run the device when necessary since it will still use some power even with the door open.

Some microwaves have a “dinner plate” setting that adds thirty seconds to the time but uses less energy than running it for two minutes since it doesn’t heat the entire device.

Another helpful fact is that microwaving in a glass bowl will use more power than cooking in a microwave-safe plastic dish since it absorbs more energy from the heating element.

In addition, you should also make sure to put your food on a rotating plate to cook evenly and prevent burning, which can increase wattage usage even if it does nothing for your food.

How to properly use a microwave?

You should avoid microwaving leftovers since doing so can increase your energy usage by 20% due to continued heating. Instead, let the food cool down and only reheat it if you need to.

If you forget about a plate of food in there for too long, don’t worry about opening the door to see what’s going on inside since this will lower the risk of fire or damage even if it does nothing for your food.

In addition, keep in mind that water boils faster at higher elevations which explains why proper cooking times are required when living at high altitudes.

This also applies to using a microwave oven. Still, there are additional precautions you can take, such as using an extra tablespoon of water to make up for any elevation changes.

What are some common myths about microwaves?

Microwaves do not cook from the inside out. Microwaving is a relatively quick process. Most foods are reheated or cooked between 90 seconds and two minutes, depending on the size, power level required, and quantity of food involved.

In addition, microwaving anything in a glass container will decrease your energy usage since metal reflects microwaves while glass absorbs them.
