How many amps are needed to efficiently run a refrigerator?
To have your refrigerator on a dedicated circuit is recommended for its best performance and to prevent overloading house wiring circuits. Most household refrigerators draw between 500 and 750 watts of power during routine operation. With a 110-volt current, a 750-watt appliance will require 6.8 amps to operate.
How many Watts Does a typical refrigerator use?
The operating wattage of most household refrigerators is in the 100-200 Watt range, with 120 Watts being especially common. The power consumption of 18 cubic-foot refrigerators (up to 19 cubic feet included in this section) ranges from 404 kWh to 553 kWh per year.
How many Watts Does It take to run a refrigerator?
Typically, it takes about 350 watts to run a small refrigerator and about 780 watts to run a bigger refrigerator.
How many kilowatts does the average refrigerator use?
The power consumption of refrigerators is 400-1,000 kWh per year (this applies to models in the 21-25 cubic-foot range). The average energy usage of modern refrigerators is 400-600 kWh per year. This translates to 33 kWh-50 kWh per month, or an average wattage of 46 to 69 Watts (this equates to an average hourly power consumption of 46 to 69 Wh).
Does a refrigerator need to be on a 20 amp circuit?
Refrigerator Circuit A modern refrigerator requires a dedicated 20-amp circuit. You may currently have a smaller refrigerator plugged into a general lighting circuit, but during any major remodeling, install a dedicated circuit (120/125-volts) for the refrigerator.
Does a refrigerator need a 15 or 20 amp circuit?
You should have refrigerators and freezers installed on a 15-20 amp dedicated 120 volt circuit. This will avoid an electrical overload due to your current wiring not being capable of handling the additional power.
How many amps should a refrigerator circuit be?
15 to 20 ampsStandard refrigerators need 15 to 20 amps and a 120-volt dedicated circuit.
Does a refrigerator have to be on a dedicated circuit?
In the US, under the NEC, a residential kitchen fridge is not required to be on a dedicated circuit. It is certainly a good idea and best practice, but not a requirement. A fridge can be on one of the minimum two required "small appliance branch circuits".
Can refrigerator be plugged into regular outlet?
Refrigerators do not require additional outlets. They can be plugged into a three-pronged socket in any regular 110-120 volt outlet.
How many amps does a refrigerator draw on startup?
Divide that by 120 volts, which is the amount of power that one outlet can produce, and you will get the amps the refrigerator needs. So, to bring it all together, refrigerators require 7 to 10 amps initially. The number of amps a refrigerator requires may lead to another concern you might have.
Does a refrigerator need to be on an arc fault breaker?
All 120-volt, single-phase, 15- and 20-ampere branch circuits supplying outlets or devices installed in dwelling unit kitchens... shall be protected by any of the means described in 210.12(A)(1) through (6): AFCI protection is required for a refrigerator.
Why does my refrigerator trip the breaker?
Every time your compressor turns on to run the cooling cycle, it will trip the breaker. When this happens, it is typically due to a grounding issue with the compressor that is causing the part to essentially become overloaded with electricity. Essentially, it means it is faulty and needs to be replaced.
Can a refrigerator and freezer be on the same circuit?
A refrigerator and freezer shouldn't be on the same circuit. Appliances like these use a lot of power intermittently, and putting too much strain on one circuit can cause frequent cooling issues, food waste, or even surges in your home.
Is it OK to plug a refrigerator into an extension cord?
Refrigerators require a lot of energy to run, and thus using a regular extension cord to power it may pose as a fire hazard as the cord may not be able to handle its energy requirements. That is why I generally do not recommend plugging your refrigerator into an extension cord for safety reasons.
Can a refrigerator share a wall socket with another appliance?
A fridge should not be sharing an outlet. The addition of other electrical devices to that outlet could overload the circuit, resulting in your circuit breaker being tripped and power supply being cut.
Can you put a refrigerator and microwave on the same circuit?
According to the 2020 version of the NEC, you can't power a microwave and refrigerator on the same circuit because each of these appliances requires a dedicated circuit, which is one shared by no other appliances or lights.
Why does my fridge keep tripping the breaker?
If your refrigerator trips often, then it is likely due to the compressor. Every time your compressor turns on to run the cooling cycle, it will trip the breaker. When this happens, it is typically due to a grounding issue with the compressor that is causing the part to essentially become overloaded with electricity.

For most domestic fridges, the amperage ranges between 3 and 5 in the case of 120 V. You need a dedicated 15 – 20 amp circuit as the starting amperage is significantly more. You should basically check the compressor’s consumption and the general specifications that your manufacturer gives.
How to determine the amperage of a refrigerator?
Once you know your refrigerator’s wattage, you can determine its specific amperage. Amperage is equal to the wattage of the unit divided by the voltage, or: Amperage = Watts/Voltage. All American homes have a voltage of 120. Also Read: The Best Outdoor Refrigerators On The Market!
How to convert watts to amps?
The formula for converting watts to amps is Watts divided by Volts = Amps. A refrigerator will use roughly half of the available amperage of a standard 15-amp circuit, and over one-third of a 20-amp circuit. Remember about a safety margin of 20-30%. A circuit should only carry 80 percent of its rated load during normal operation.
How many amps does a single pole breaker handle?
Single pole breakers protect a single energized wire. They supply 120 volts to a circuit and can handle 15 to 20 amps. This type of breaker protects two energized wires and occupies two slots on a breaker panel. They supply up to 240 volts to a circuit and can handle between 15 and 200 amps.

The average refrigerator uses approximately 725 watts of electricity and 15 to 20 amps, which can equal 10 percent or more of your home’s total energy usage. To understand better you must know some technical terms. Wattage, measured in watts, measures the rate of energy converted to electricity, usually per hour.
How many amps does a refrigerator use?
Most refrigerators run between 3 to 6 amps (the unit of measurement for electrical current), but this represents normal operation and cycling of the cooling system. A refrigerator can spike at peak usage up to 15 amps, and that's what most electricians design circuits around, since that's the worst case scenario. Advertisement.
Why Safeguard Your Refrigerator?
You can probably manage a few days without a microwave, for example, but if the refrigerator loses power , you only have a few hours before all of the food in the refrigerator and its freezer warms into a dangerous temperature and needs to be thrown out .

A GFCI, or Ground-Fault Circuit-Interrupter, is a device that protects you from receiving electrical shocks from faults in electrical devices. Since being introduced into the 1971 National Electrical Code, the number of electrocutions in America has dropped dramatically. The way it works is by comparing the input current on the hot side to ...
How does a power supply work?
The way it works is by comparing the input current on the hot side to the output current on the neutral side. If there is a difference in current it indicates that there is a leak and shuts off the power supply. This is also known as ‘tripping the circuit’.
