How Many Amps Does a Refrigerator Use?

The average refrigerator uses approximately 725 watts of electricity and 15 to 20 amps. This energy consumption equals 10 percent or more of your home’s total energy usage.

Wattage measures the rate of energy converted to electricity, per hour and its units of measurement are watts. Your refrigerator has an energy consumption label, stating, at the very least, its wattage. This number determines your unit’s amperage.

To get the amperage of your fridge, take the total wattage and divide it by Voltage. Bear in mind that all American homes have a voltage of 120V. Therefore, figure out the wattage of your refrigerator and divide it by 120.

It’s still important to comprehend the technical terms associated with the energy consumption of your home appliances, specifically your fridge. Knowing this will help you make a sound decision on what kind of refrigerator you ought to buy.

Amperage

The amperage of your fridge is directly proportional to the wattage of the refrigerator. Meaning the higher the wattage, the higher the amperage. You derive this from dividing the wattage to a constant of 120V, now this seems too technical, but here’s the breakdown for more clarity.

If your refrigerator wattage is 360W, then your amperage is 360/120 which equals to 3Amps.

An amp measures the electricity flow rate and determines the sizes of the wire and circuit breakers. When more than one appliance tends to work on the same circuit, the total amps for every machine should add up to less than the wire and circuit breaker rating to avoid circuit overload. A circuit overload gets the wires overheated and results in a fire hazard.

Refrigerator amps translate to the amount of electrical energy used by a refrigerator compressor to cool down the compartment. For most domestic fridges, the amperage ranges between 3 and 5, given that their wattage ranges from 360W to 600W.

Wattage

As stated earlier, wattage measures the rate of energy converted to electricity per hour. The division of wattage by Voltage, which is 120 Volts in all American homes, gives you the amperage of your appliance.

Calculating the Amperage

Amperage equals the unit’s wattage divided by Voltage. To put simply, Amperage = Watts/Voltage. And as stated earlier, In the US, every home has 120 Voltage.

When you consider this fact, any refrigerator of small size, for instance, Furrion 1.7 cu.ft 110-120 Volt Compact, Energy Efficient, Single-Door Refrigerator having up to 240wattage would fall under the restriction of 2amps that is prevalent in most homes.

Small recommended fridges like ROVSUN Double Door Compact Refrigerator with Freezer, 3.2 CU FT use the Energy Star technology, which can reduce the power consumption of a refrigerator.

When it comes to domestic refrigerators, the consumption power is in the range of 100-200 watts. Meaning a newer model of a domestic fridge averagely uses 1.2 to 3 Amps. Conversely, old models of both domestic and commercial refrigerators use more energy.

Daily Kilowatt Hour

It’s essential to know your refrigerator’s daily kilowatt-hour energy consumption. To do so, multiply the wattage by 24, or the number of hours your refrigerator uses per day. Divide that by 1000 and calculate how much you pay on average, depending on the charges per daily kilowatt-hour.

Saving Energy

To save energy consumption, purchase the smallest refrigerator that’ll work for your home. Pick one that lacks an ice maker or one that has a switchable ice maker. If you have an old model, replace it with a newer model that meets the energy saver standards established by the US Congress.

We recommend The BLACK+DECKER BCRK17W if you are looking to buy a refrigerator that conserves energy and works effectively.

Factors That Influence the Energy Consumption of Your Fridge

Factors That Influence

Location

The positioning of your refrigerator affects its performance. For instance, placing your fridge next to the oven or in a warm area that lacks ventilation ultimately will make the compressor have to consume more energy.

Size

Small fridges generally take less energy; the vice versa is true. If you get a big fridge, prepare yourself for high electricity bills.

If you want to get a perfect size fridge, then you can see our guide about the average refrigerator weight. This article helps you to get a perfect one.

Usage

After using your fridge, ensure you close its door. Opening the door frequently or having it open for long will make the compressor operate harder in order to cool.

Also, an empty refrigerator works harder to cool compared to a well-stocked fridge. Therefore, you should often stock your freezer to avoid high energy consumption.

Temperature Setpoint

For safe storage of foods, set the temperature of your fridge in the range of 3-5 degrees Celsius. A factory setting might keep your fridge unnecessarily cool.

Age

Older models lack the energy-saving feature available in newer refrigerator models.

Condition

Worn out seals on your refrigerator indicate less efficacy. Efficiency is necessary for an appliance to work, ideally putting into consideration all variables that affect your appliance’s efficiency.

A good fridge is an Energy Star-rated fridge, and we recommend EdgeStar CRF321SS 19 Inch Wide 3.1 Cu. Ft. Energy Star Rated Fridge. It is affordable and efficient as a domestic fridge.

Types of Amp Breakers

Types of Amp Breakers

If you run too many appliances at once, you risk short-circuiting. To avoid short-circuiting, use circuit breakers.

Circuit breakers interrupt the flow of electricity to specific areas of your home and protect you from overloading your electrical system. One of the best circuit breakers that has a manual reset is the T Tocas 200 Amp Circuit Breaker with Manual Reset High Amp Switchable, Waterproof, Flush-Mount Circuit Breaker.

Electrical requirements and circuit breaker size for refrigerators are a 115 or 120-volt individual, properly grounded branch circuit, protected by a 15 or 20 amp circuit breaker or time-delay fuse.

Refrigerators ought to be on a circuit. Start-up amps and wattage are usually three times more than running amps or watts. Therefore, a circuit breaker is necessary to avoid overheating, which leads to short-circuiting.

There are two types of circuit breakers, namely single-pole circuit breakers and double-pole circuit breakers. Of the two, the ideal one for large appliances like fridges is the double-pole circuit breaker.

Using large appliances like fridges, dishwashers, washing machines, et al. needs a keen understanding of their energy consumption. Failure to know will lead to unprecedented high bills. Therefore, when purchasing an appliance like a refrigerator, calculate its amperage and the overall charges you’ll incur when using it.

Fortunately, with the above information, calculating the amperage and picking the right fridge will be a piece of cake. If you are looking for a top-quality refrigerator that maintains consistent temperatures, we recommend the GE APPLIANCES GNE25JSKSS refrigerator.
