How many amps does an electric oven draw?

Electric ovens use a lot of electricity; below, I'll tell you exactly how many amps. 

On average, an electric oven can draw between 20 and 60 amps of electricity. The specific number of amperes depends on the size and model of the electric oven. The exact current value is indicated on the label with the circuit parameters or in the user manual. However, you will have to calculate the booster value if it is not listed on the label. 

Continue below to learn more about booster ratings and how to calculate them.

Average current of electric ovens

Electric ovens typically draw between 20 and 60 amps.

The specific amperage value depends on the size, number of burners, and power requirements (in watts) of the oven. The two most common electric ovens are standard single door and microwave ovens. 

  • Standard electric ovens draw an average of 1,800 to 5,000 watts at 21 amps. 
  • Microwave ovens draw an average of 800 to 2,000 watts at 10 amps. 

Please note that these measurements represent the average ampere rating of electric ovens in the United States. The exact amperage rating of your electric oven depends on its voltage and the power required. You will need a simple calculation to get an accurate amp measurement. Typically, devices that require more power require more current to operate. 

What is the amplifier rating?

Rated amperes refer to the amount of current flowing through the dedicated circuit of the device. 

Three parameters are used to measure the required power supply for a device: voltage, power, and current. While we are more focused on current (amps), it is also important to understand how these three parameters work together. 

  • Voltage is the pressure or force required to supply current to a circuit breaker. 
  • Current (in amps or amps) is the electrical current drawn from a wall outlet or power source. 
  • Power (power) is the electricity required to power and operate the appliance. 

The amp rating tells you the maximum amount of electricity it will draw from the outlet while it is operating. 

Electric ovens are energy-intensive appliances. Depending on size and model, they can draw an average of 20 to 60 amps of electricity. Connecting the oven to an appropriate outlet is important to avoid problems with the amplifier circuit. 

Connecting the oven to an electrical outlet incorrectly can cause several problems:

  1. The oven will not work due to lack of power. 
  2. The oven will draw too much current from the outlet, which may overload the amplifier breaker. 
  3. Risk of electric shock and fire due to risk of overload. 

By consulting the manual, you can determine the exact number of amps required for your electric oven. They also come with installation requirements and guidelines that you can follow. However, if it's not written in the manual or you don't have one, you'll have to calculate the power rating of your electric oven. 

How to calculate the rated current of your electric oven

All electrical appliances have a label containing information about the parameters of the circuit breaker. 

For electric ovens, you will usually find this label on the back next to the power terminals (where the power cord is located). This label contains information about the requirements for oven power, current and voltage. However, most labels only list wattage and voltage, so you'll have to calculate the current rating. 

Calculating the rated current of any electrical appliance is a one-step process. 

The first thing you should do is find the total watts and volts of the device. As mentioned earlier, you can find them on the label or in the user manual. You must divide the power by the voltage to get the amp value.

W/Voltage = Amp

For example, an electric stove has a power of 2,400 watts and a voltage of 240. An amp is calculated as 2,400 divided by 240 equals 20 amps (2400/240 = 20). The resulting value is the average amperage of your electric stove. You will need to use an outlet capable of supplying 20 amps to your electric stove's switch. 

What does the amplifier rating say?

The ampere rating is the expected amount of current drawn by the device. 

We say "expected" because this number may not be entirely accurate. When calculating the current strength, factors such as the age of the device, the state of the dedicated circuit and its functions are not taken into account. This results in minor differences between the expected electricity consumption and the total amount shown on the electricity bill. 

If so, why is it important to find the power rating of your device?

As we have said, it is important to meet the requirements for amplifiers and outlet power. Another reason is that the current rating reflects the number of amps drawn if your device is in perfect working order. You will be able to determine that something is wrong with the device if the rated current and the actual consumption do not match. 

This applies not only to electric ovens. The rated current is also used for other appliances such as air-conditioned refrigerators and hoods. 

Factors affecting the requirements for electric oven amplifiers

The main factors affecting the current consumption of an electric oven are:

  • Oven size
  • Type of heating system used by the stove 
  • How often the oven is used

Large ovens require more powerful heating systems to achieve high temperatures. Usually more burners are needed to store heat and maintain it. Electric ovens are already energy-hungry appliances, so expect larger models to use more electricity than usual. 

Another important factor is the energy efficiency rating of the oven. 

The efficiency rating refers to the amount of wasted power. At the same time, electricity is supplied from the socket to the circuit breaker of the instrument's amplifier. All appliances, such as electric air conditioners and electric stoves, must have an efficiency rating before they are sold to consumers. [1]

A standard single oven has an energy efficiency of 12%.

This number is incredibly low compared to a fryer's 60% efficiency. Electric ovens may need more amps because most of the current they draw from the outlet is wasted as heat.
