How many amps should a fridge draw?
Amperage for most household refrigerators, is anywhere from
3 to 5 if the voltage is 120
. A 15 to 20 amp dedicated circuit is required because the in-rush amperage is much higher. The average amperage is lower because the compressor isn’t running all the time, this is often measured in kilowatt hours KWH.
Can I run a refrigerator on a 15 amp circuit?
Most refrigerators run between 3 to 6 amps, with that said,
a refrigerator can spike at peak usage up to 15 amps
. It’s best to take into consideration worst case scenarios. You should have refrigerators and freezers installed on a 15-20 amp dedicated 120 volt circuit.

How much electricity does a new refrigerator save?
A 1986-era 18 c.f. fridge uses 1400 kWh a year, while a modern energy-efficient model uses only 350 kWh — a whopping 75% reduction. At 15¢ kWh, trading in a pre-1986 fridge for a new efficient one would save about
$158 a year
in electricity costs. And some older fridges are even worse than the average.
How many amps does a 12V fridge draw?
A 12 volt fridge uses
between 30 and 55 Ah
(amp hours) per day on average.
Can I run 2 refrigerators on the same circuit?
Even with all of these cautions, there may be some cases in which you must plug two refrigerators into a single outlet. In this case,
you can install a split-wired receptacle that serves two circuits in your home
. This allows you to draw from two separate circuits, rather than overload one.
How many amps does a small fridge draw?
In general, mini-fridges use between 55 watts and 85 watts, but many can run up to 240 watts. In this case, when applying the formula, most mini-fridges will use
2 amps or less
. This is extremely useful if you are thinking of buying one for your dorm as this is a restriction set by most universities.
Does a refrigerator need a 15 or 20 amp outlet?
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 fridge need a GFCI outlet?
Residential Kitchen
In a dwelling unit (residential), GFCI protection is only required for kitchen receptacles that serve the countertop surfaces.
There’s no requirement to GFCI protect receptacles that serve a refrigerator
. Unless the fridge is plugged into a countertop receptacle.
Can you plug refrigerator into regular outlet?
Refrigerators don’t need special outlets.
They can be plugged into a standard 110-120 volt outlet so long as the socket is three-pronged
. However, it’s best if your refrigerator is on its own dedicated circuit. It may even be required by the code in your area.
Can I turn off the refrigerator every night?
The short answer is
no
, says LeeAnne Jackson, health science policy advisor at FDA’s Center for Food Safety and Applied Nutrition. “Refrigerators should be maintained at a constant temperature setting at 40 degrees Fahrenheit or below,” writes Jackson in an email.
What uses most house electricity?

- Water Heating. …
- Appliances. …
- Lighting. …
- Television and Media Equipment.
Does a refrigerator in the garage use more electricity?
A refrigerator in an uninsulated garage will require a lot more energy to run during the hot summer months and may not operate correctly if the temperature gets too cold.
90 degree environment will use 45-50% more energy than one in a 70 degree environment
.
Are fridges expensive to run?
Running a fridge-freezer costs around seven per cent of your total energy bill
, because it’s one of the few appliances that you have to keep on the whole time.
How can I tell if my refrigerator is using too much electricity?
If the coils or expansion valve become blocked, the compressor will run constantly and use excessive energy
, even though no cool air will reach the refrigerator compartment. If the compressor fails, it must be replaced or you need to buy a new refrigerator.
How much does it cost to run a fridge in the garage?
It will cost
approximately $100 (annually)
to run a refrigerator in the garage. This will come from utility bills due to the added load on the electrical circuit. The cost can vary depending on the size of the fridge.
Will a new refrigerator save me money?
According to EnergyStar.gov, buying a new ENERGY STAR certified refrigerator to replace your existing model that’s over 10 years old
you could save up to $1,100 on energy costs over the appliance’s lifetime
! That’s a lot of money, and reason enough to purchase a new refrigerator for many.
Do refrigerators use more energy as they get older?
Does Age Matter? Another important consideration is that
fridges become increasingly less efficient as they age
and the cooling system degrades. 5-year-old fridges consume 10% more energy, 10-year-old fridges consume 20% more energy, and fridges 15 years old or more consume at least 30% more energy.
How much does it cost to run a 10 year old refrigerator?
If you pay $. 10 for electricity per kWh, that means the aging refrigerator is costing you about $. 55 per day, $16.67 per month, and
$200 per year
. A modern-era Energy Star-rated fridge, by comparison, might only use 350 kWh annually.
How long will a 12V fridge last on a 100Ah battery?
A 100Ah lead-acid deep-cycle battery will run a fridge using 630kWh/year for
13.3 hours
