How Many Amps Does a Refrigerator Use?

Article Brief Review

The number of amps used by a refrigerator affects how you may arrange your electrical installations and how much extra load you can put on a circuit breaker.

It makes no difference if the installation is for a home, a business, or an RV.

At best, overloading an electric circuit will cause a breaker to trip or some of the gadgets to blow a fuse.

However, it may also result in a short circuit, which can cause a variety of additional issues such as fires and damaged electrical systems, as well as damage to electrical equipment.

A refrigerator consumes how many amps?

The majority of refrigerators, according to the US Department of Electricity, will need between 15 and 20 amps and approximately 700 watts of energy.

This figure, however, will be determined by the voltage of the refrigerator, its location in your house, its age, usage, the number of cubic feet the fridge consumes, and the temperature setpoint.

Is it necessary to have a refrigerator on a separate circuit?

Yes, according to Tru-Line Electric specialists, placing a refrigerator on its own dedicated circuit is the best practice for any home.

Preparing the electrical outlet for a 15-amp draw in advance ensures that it is ready to manage an unexpected surge in demand.

Mr. Electric further claims that the National Electric Code (NEC) necessitates the installation of dedicated circuits for large appliances.

Alternatively, a refrigerator power outlet may be supplied via a branch circuit that connects back to the circuit breaker.

For a refrigerator, what size circuit breaker am I looking for?

In older houses, there’s an issue that’s prevalent.

If you use too many gadgets in the kitchen at the same time, you will short out the electrical circuits.

Every appliance and light source linked to that circuit will be turned off at the same time as a result of this.

Power circuit breakers are devices that stop the flow of electricity to particular parts of your house, and they are intended to prevent you from overloading your electrical system.

Refrigerators need a 115 or 120-volt individual branch circuit that is properly grounded and protected by a 15 or 20 amp circuit breaker or time-delay fuse, with the manufacturer determining the breaker size.

Refrigerators should be connected to a dedicated circuit, and it is important to note that the start-up amps and wattage are typically three times more than the operating amps and wattage.

The “amperage” of an electrical current passing via a circuit is a unit of measurement for this current flow.

The unit of measurement for current is the “amp.”

In order to prevent a wire from overheating, it is necessary to utilize the proper size wire for the amps that are needed. In most cases, a conventional home circuit has a capacity of 20 amps.

Current is pushed through an electrical wire by the pressure created by the voltage.

Currently, there are two standard voltages in use in the United States: 110V and 220V.

Circuit breakers with a single pole are known as single-pole circuit breakers.

These are the most common types of breakers that may be found in a house or apartment. Single-pole breakers are used to prevent a single electrified line from being damaged.

They are capable of supplying 120 volts to a circuit and handling 15 to 20 amps.

Circuit breakers with double poles

This kind of breaker covers two electrified wires and takes up two slots on a breaker panel, which is ideal for small homes.

They can provide up to 240 volts to a circuit and manage currents ranging from 15 to 200 amps.

This kind of circuit breaker is required by large appliances such as refrigerators, dishwashers, and dryers.

An amp is used to calculate the rate at which electricity is used.

The diameters of the chain and course top are determined by electrical regulations based on the square root of the amps used in the circuit.

A course overload causes the wires to get irritated, resulting in a domino reaction in a shot hazard.

When more than one appliance is grafted onto a single circuit, the total amps for all of the jobs tend to add up to a lower quantity than the cable and route roller ratings for that particular circuit.

Refrigerator amps are a unit of measurement for the total amount of electrical energy required by a refrigerator compressor to chill a refrigerator compartment.

Most home refrigerators use an amperage between 3 and 5 amps when connected to a 120-volt electrical supply.

Because the in-rush amperage is much higher, you’ll need a dedicated 15 – 20 amp circuit.

Because the compressor is not in use the whole time, the median amp is small and lightweight.

It is measured in kWh on a regular basis (kilowatt-hours).

Once the door is opened and the fridge is placed inside, it consumes a significant amount of additional electricity.

After all, the appliance is in the process of being turned on, and all of its systems are operational.

However, the refrigerator does more than just devour a collection of items that you place in it.

In addition, this occurs when you are standing in front of your refrigerator, distracted with the door open, gazing at the interior with a regulator preoccupied with uncertainty.

As soon as the optimum temperature is achieved, the refrigerator devotes its energy to reacting to friendly doors or maintaining continuous heat throughout the night when it is not in use.

Individuals scenarios representing the total amount of energy that humans have consumed by the device.

Simply look for the manufacturer’s label on the outside of your refrigerator to find out how much energy it consumes.

Furthermore, it will give you a general understanding of the subject, including the amps required to operate your refrigerator.

An authority pipe with 15 to 20 amps that have been dyed in the wool is thus required for a refrigerator.

It has to be the only piece of equipment that is connected to that particular socket.

Once you have determined the amps and volts of the refrigerator, you will be able to determine the wattage.

To get the watts, you would multiply the volts by the amps, which would give you the watts.

With this information, you will be able to use the Energy Star “Flip Your Fridge” Calculator to determine how much energy you will save by swapping your current refrigerator with a more energy-efficient model.

Because, after all, the refrigerator consumes about 13 percent of the energy used by your house, thus outshining its efficiency the less expensive it is to run your home.

What amperage does a refrigerator consume?

The precise amperage of each refrigerator is determined mainly by the size of the appliance.

Larger refrigerators have the ability to chill more efficiently, but larger compressors are required.

The compressor, on the other hand, is the component of the refrigerator that uses the most electricity.

The light bulb in a refrigerator, in addition to the compressor, is another major user of energy.

However, since it is typically a standard 40W bulb, it does not contribute to the variance.

Even while the vast majority of contemporary home refrigerators are rated between 3 and 6 amps, depending on their actual size and how power-hungry the compressor is, the extreme range may be as high as 1 to 15 amps.

The amperage of a refrigerator may be calculated with relative ease if the wattage of the refrigerator is known.

All that is required is a division of the amperage by the voltage that they are provided with.

For example, a 480-watt refrigerator will use 4 amps while operating on 120 volts of electricity.

However, determining the wattage of your refrigerator may be a difficult task.

Here are a few illustrations:

  • A refrigerator with a capacity of 18 cu ft will use about 6 to 7 amps.
  • A modest freezer will use about 1 amp.
  • Depending on the model, a beverage cooler will use between 6 and 12 amps.
  • A modest wine refrigerator will use about 20 amps from the circuit breaker.

Manufacturers seldom mention it in their literature, and they always tout yearly power usage statistics that, due to the nature of the refrigerator cycle, may be deceptive.

It is more often than not the starting wattage that is specified, which is determined by the locked rotor amperage of the compressor and is much greater than the current that the refrigerator would consume constantly most of the time.

Amperage Factors for Refrigerators and Other Appliances

Other appliances, such as a microwave, may have an impact on the amount of current that a refrigerator consumes in the kitchen if they are connected to the same circuit.

However, there are a variety of additional variables that influence how much energy a refrigerator consumes.

The location of your household’s refrigerator

It will be considerably more difficult for the compressor to operate if the refrigerator is placed in a warm location, such as next to the oven or in an area with inadequate ventilation.

The refrigerator consumes a certain amount of cubic feet.

In general, larger refrigerators use more energy than their smaller counterparts.


If the refrigerator door is left open for an extended period of time or is opened often, the compressor will have to work harder in order to chill the surrounding space.

When compared to a refrigerator that is fully filled, an empty refrigerator will have to work harder since every time you open its door, more ‘warm air’ will replace more ‘cold air.’

Setpoint for the temperature

A factory setting may cause your refrigerator to operate at a lower temperature than is required in your home.

Maintaining a temperature in the range of 3 – 5 degrees Celsius is recommended for safe food storage.

Using a thermometer of this kind, you can ensure that the temperatures in your freezer and refrigerator are not too frigid.


Refrigerators that are more than a decade old often have poorer energy efficiency than modern refrigerator models.


Take a look at the seals that surround the door.

A lower level of efficiency will be achieved if the seals are worn out.

It is essential to bring home an Energy Star-rated refrigerator in order to minimize the amount of electricity used by the compressor.

Another method you may reduce your electricity use is to be vigilant and to understand how to correctly operate your refrigerator, among other measures.

It is not recommended to keep an empty refrigerator running.

The greater the quantity of food in your refrigerator, the less electricity it uses.

This occurs because the items that you store inside the refrigerator block cold air from escaping when the refrigerator door is opened.

As a result, it does not have to work much harder in order to freeze again.

Older refrigerators should also be avoided since they use a greater amount of energy.

These do not feature the Energy Star technology that helps you save money on electricity.

With a smaller-sized refrigerator, you may expect to see a reduction in energy usage.

Defrosting your refrigerator on a regular basis may help to maintain it in good working order and reduce the amount of electricity it consumes.

You may also save money on electricity by avoiding allowing your refrigerator to sit directly in the sunlight.

The number of times the refrigerator is opened and closed should be minimized, as well as the refrigerator is placed on a flat surface.

Generally speaking, despite the fact that a refrigerator uses a significant amount of electricity, you are unlikely to notice a difference in your energy costs when you utilize mini-fridges.

The operating expenses of a typical refrigerator are about 10 USD per month on average.

That may not seem like a huge issue for a single-family home, and members of the household are unlikely to give it much consideration.

However, for college dormitories with 100 or more rooms, 5 dollars a room can quickly add up when multiplied by the number of rooms.

As a result of these considerations, schools place limits on the amount of electricity that refrigerators may use.

The Truth About How many Watts Refrigerator Use?

Our Final Thoughts

Once you have estimated the amperage consumption of your refrigerator, you should attempt to decrease the consumption as much as possible to keep your costs as low as feasible.

Frequently Ask Questions

Is it possible to operate a refrigerator on a 15-amp circuit?

The suggested best practice for homeowners is to install the refrigerator on a separate dedicated circuit from the rest of the house.

Generally speaking, refrigerators use between 3 and 6 amps; but, at peak usage, a refrigerator may consume up to 15 amps.

Refrigerators and freezers should be placed on a dedicated 120-volt circuit with a power rating of 15-20 amps.

A fridge requires a 20-amp circuit, do you think?

To operate a contemporary refrigerator, a dedicated 20-amp, 120/125-volt circuit must be installed.

In the meanwhile, you may have a smaller refrigerator that is connected to a general lighting circuit, but during any significant renovation, you should have a dedicated 120/125-volt circuit built just for the refrigerator.

What is the maximum amperage that a refrigerator can draw?

amps are the amount of electrical current that a refrigerator’s compressor needs to chill the compartment it is located in.

When the voltage is 120 volts, the amperage of typical home freezers ranges from 3 to 5 amperes. Because the in-rush amperage is much greater, a dedicated circuit of 15 to 20 amps is needed.
