For these reasons, it ’ sulfur authoritative to understand how many amps a microwave uses .
Knowing how many amps a microwave uses can help you determine how fast food will be cooked and how a lot the appliance will cost to operate. In fact, some microwaves have variable electrical power settings, which makes it harder to pinpoint how many amps it uses. We ’ ra going to take you through everything you need to know about microwave amps and how to know how many amps your microwave uses .

What is an Amp?

An adenosine monophosphate ( amperage ) is a unit of measurement of measurement that measures how many electrons are located in an electrical racing circuit. Amps are used to determine how mighty a lap is, and in most cases, higher amperage means more power. amperage is used to measure electric circuits across the worldly concern, so it ’ s not a unit of measurement that ’ s particular to the United States or other countries .
silent, there are other factors to consider when it comes to determining the ability of something like a microwave. While amps provide a baseline measurement of a circuit ’ second ability, adenosine monophosphate cultivate hand-in-hand with electric potential .
electric potential is a unit of measurement of measurement that measures the pressure of an electric circuit. When you multiply the amps and electric potential of a circuit, you end up with electrical power. electrical power is the across-the-board measurement of electricity for most electrical appliances like microwaves .

Calculating Microwave Amps 

There are a few ways to calculate the amperage of a microwave. The simplest direction is to refer to your owner ’ s manual, which has most of the unit of measurement ’ s electric requirements and outputs. Another method for calculating the amperage of a microwave is to divide the electrical power by the electric potential.

Product Information 

first and foremost, you should look for your microwave ’ mho intersection data. If you have the owner ’ s manual, there ’ s a full luck you won ’ deoxythymidine monophosphate have to calculate the amperage because it will tell you. With this in mind, there are ways to find product information if you don ’ t have the owner ’ s manual .
The best means is to look for the sword that manufactured the microwave. The mark diagnose is typically found on the face of the microwave .
You can besides look for the exemplary numeral, which is typically located on the back of the microwave. With this information, you can go on-line to find a digital version of the owner ’ s manual .

Divide Wattage by Voltage 

If the owner ’ s manual doesn ’ t have the amperage of the microwave or if you can ’ triiodothyronine find that information on-line, you can use a simpleton rule to find the amps a microwave has. To find the amps of a microwave, you can divide the electrical power by the voltage .
This will give you the amperage of the microwave. Most outlets in the United States are between 110 and 120 volts, so you can take that number and divide it by the electrical power of a microwave. For example, a 1,200-watt microwave with 120 volts has 10 amps .
Most microwaves have wattage settings displayed on the face or rise of the microwave .

High Wattage Microwaves Vs Low Wattage Microwaves 

Microwaves come with many electrical power options. Microwaves with gamey wattages are more powerful but monetary value more to operate. While your meal might be more evenly cooked and finished faster, your electrical circular will suffer. therefore, it ’ mho crucial to examine the advantages and disadvantages of high-watt microwaves and low-watt microwaves .

High Wattage Microwaves 

We ’ ll depart with high-wattage microwaves. high electrical power microwaves ( 1,200+ watt ) cook food quickly and provide a more tied cook. These microwaves are typically larger ( on average ) and come with promote settings or cooking options. This makes high-watt microwaves utilitarian for people who want their food cooked promptly and evenly .
That said, there are a few drawbacks to using a high-watt microwave .
The biggest return is that high-watt microwaves are more expensive to operate. unfortunately, more electrical power means more money added to your electric bill. Another trouble is that you need the right power exit to run a high-watt microwave. Having excessively few amps will lead to several problems and can cause electrical hazards. It besides limits your ability to use things like extension cords.

Low Wattage Microwaves 

Microwaves with low electrical power ( 600 watt ) are great for people who don ’ t need a massive/expensive microwave .
A low-watt microwave is bum to operate and can be used with most outlets. Plus, the humble electrical power makes these microwaves more compatible with propagation cords and you can plug multiple appliances into the same wall socket .
While low-wattage microwaves have their benefits, there are besides several drawbacks. The biggest trouble is that they take longer to heat items. Another problem is that the food is typically not cooked evenly. therefore, these microwaves are designed for people who prefer savings over food quality .
It ’ south besides important to note that there are microwaves with variable electrical power. These are typically high-watt microwaves with settings that range from 1,000 watts to 1,200 watts.

Making Sure You Have the Right Microwave for the Job

When you ’ rhenium looking for a microwave there is more to consider than the amperage. While amps are crucial, you besides need to consider the size, early electrical requirements, and how you ’ ll get power to the microwave. We ’ re going to take you through some other factors to consider .

Microwave Size 

first and foremost, we ’ ll start with the size of the microwave. There are several microwave sizes to choose from and some can be placed in singular locations ( like above an oven or near a cabinet ) .
For this reason, you should measure the space you want to place a microwave in. You should besides consider how big of a microwave you need for the meals you plan on cooking .
typically, microwaves are measured by how many cubic feet of space they have inside. We have some examples below.

  • Compact: less than 1 cubic foot 
  • Mid-size: about between 1 and 1.3 cubic feet
  • Family size: between 1.4 and 1.6 cubic feet 
  • Full-size: About 2 cubic feet 

We recommend installing microwaves in locations that won ’ t take up unnecessary space, which is why wall-mounted microwaves are great choices .

Electrical Requirements 

following, you want to consider the electric requirements of a microwave. This includes the voltage and amperage. The good newsworthiness is that most kitchens have outlets that support 15-20 amps. This means that most kitchens can handle most microwaves, tied higher electrical power products .
That said, we recommend giving a microwave its own release. Plugging other appliances into the lapp mercantile establishment can draw excessively much amperage and create electric problems .

Using Extension Cords 

An reference cord makes a microwave more versatile. Therefore, many people want to use a microwave with an extension cord .
While you can plug a microwave into an extension cord, we recommend against doing so .
This is because some wires are not slurred adequate to handle high-watt microwaves. If you ’ re going to use an extension cord, we recommend using a 14-gauge telegram. Using a 14-gauge wire ensures you don ’ t have any issues with amperage .

Microwave Operating Cost 

Operating a microwave costs money and most people spend about $ 10 per year on microwave custom. When you use a microwave it will increase your electrical bill but the amount your bill increases depends on how often you use the microwave.

Calculating the Cost of Your Microwave

While the average microwave costs about $ 10 per year to run, we ’ re going to provide you with a formula to determine the power custom of your specific microwave. Follow the steps below .

  1. Estimate how long the microwave is used for each day. For example, we’ll use 15 minutes.
  2. Multiply the wattage by the hours a microwave is used per day): 1,000 watts x .25 hours (15 minutes) is 250 watts
  3. Convert the wattage you get into kilowatts, which is a smaller unit of measurement for wattage. You divide the wattage by 1,000 for the result. 250 watts divided by 1,000 is .25 kilowatts.
  4. Take the kilowatts and multiply that number by the cost of electricity per day. The result for 15 minutes is about $.02 per day.
  5. Multiply that number by the number of days in the year, which is 365.

With your microwave, you can plug your numbers into these equations to come up with the solution.

Wrapping Up 

Knowing how many amps your microwave has is important for respective reasons. It can help you determine how much it costs to operate a microwave and gives you an theme of how much power it can handle. If you have a low-amp microwave you can use it in a high-amp power mercantile establishment .
On the other hand, a high-amp microwave in a low-amp power release can lead to electric problems, damaged equipment, and even fires. consequently, we recommend knowing the amps of your microwave before using one.
