So, you want to install a ceiling fan. Or maybe you are confused as to how you rack up your monthly or yearly electricity bills and would like an estimate and breakdown. The size of your ceiling fan is the primary determinant of how many amps it will consume, among other factors, such as speed.
The electricity consumption also varies from one brand to another. This article will provide an overview of what to expect from each size, although the average cooling fan requires less than an amp.

How Many Amps Does a Ceiling Fan Draw?
A Ceiling fan draws less than an amp of energy for each hour of use. The energy the appliance will consume depends on the setting it runs on, but even the highest speed shouldn’t require more than 0.65 amps. It can be lower; set it to a low rate, and you can use as little as 0.17 amps.
There are many cooling options in the market today. But if you are conscious about your power usage, you will naturally wonder which is best for you.
An air conditioner requires more energy, consuming between 15 to 60 amps. On the other hand, a ceiling fan requires less, even though you cannot compare both devices’ functions and cooling capabilities.
A ceiling fan will come in handy in temperatures where you don’t need too much cool air. Although it isn’t as effective as an air conditioning unit, you can still use a ceiling fan in the cooler climes, like the early days of summer.
At most, it draws an average of 0.5 to 1 amp. The voltage determines how high the number goes, as well as the speed and size.
For instance, a large ceiling fan will consume a higher voltage and higher number of amps for each hour of use, while a smaller one will stick within two decimals and less than 0.5 amps.
How Many Ceiling Fans Can be on a 15 amp Circuit?
It depends on each ceiling fan’s electrical consumption per unit and hour. But let’s dedicate 1.5 amps to each ceiling fan since the larger and most optimized versions will not consume more than 1 amp of electrical current for each hour. On a 15 amp circuit, you can connect between eight to ten ceiling fans.
Dedicate 1.5 amps to each one to ensure no electrical starvation from any angle. This is also to ensure a short circuit does not affect the performance of your device.
Since the average ceiling fan consumes between 0.5 to 1 amp of electrical currents, a 15-amp circuit will host eight of these gadgets to ensure plenty of protection.
Avoid going above eight ceiling fans to allow room for the additional power surge that may happen now and then.
How Much Electricity Does a Ceiling Fan Use in 24 Hours?
You can calculate the amount of electricity your ceiling fan uses in twenty-four hours, but you need a number of details. These include the number of hours you run it daily, assuming you don’t use the fan all day. You also need to know the number of amps it consumes for each hour, the wattage, and the price you pay for each unit of energy.
The average ceiling fan consumes a low amount of energy. It consumes an average of 120 watts each hour.
The watt means the rate of energy consumption on an hourly basis.
Your electricity consumption will be ultimately determined by multiplying the number of wattage by the number of hours of use. That will give you the kilowatt rating; let’s do that now.
The formula for deriving kWh:
kWh = Ceiling Fan Wattage x Duration of Use (hrs) / 1,000
Estimated Cost = kWh * Average kWh rate in the US
The size of the ceiling fan determines how much energy it will consume. You will often find a ceiling fan between the range of 42 to 48 inches, with an average wattage consumption of 55 to 100 watts on each amp it uses.
Let’s assume the ceiling fan uses 1 amp for this calculation lesson.
At 55 watts per hour and for five hours daily, multiply it by the number of hours and divide by 1000 to gauge the kWh rating. Fifty-five watts x 5 hours daily, divided by 1000, results in 0.275 kWh.
Electricity consumption is calculated by multiplying your kWh consumption by your country’s electricity cost.
Daily electricity consumption for a ceiling fan of 55 watts = 0.275 kWh when used for five hours. Assuming the average kWh rate in the US at 15 cents per hour, you will spend a total of $0.04 daily.
How Many Amps Does a 52,56,60,70 Inch Ceiling Fan Pull?
The ampere consumption of each device varies and depends on the size and functionality. 52, 56, 60, and 70 are pretty common in the household, so let’s examine their electricity consumption one after the other.
A 52-inch ceiling fan consumes about 0.72 amps of electricity. Fifty-two inches is a good size for the bedroom, living room, or small garage. If you decide to install this appliance in any of these areas, you will not use up too much electricity monthly because it does not draw a high amperage.
A 56-inch will also do well in your living room, bedroom, or garage. It consumes about 0.85 amps for each hour of use, at an average of 55 to 120 watts per ampere. Again, this is a reasonable amount to consume, and you will not rack up an exorbitant bill at the end of the month.
Are you also curious about a 60-inch fan’s energy consumption? It pulls 1 amp for each hour you use it. Meanwhile, a 70-inch fan consumes 1.25 amps hourly.
Does a Ceiling Fan Need Its Own Circuit?
Barely! A ceiling fan consumes meager electricity, which means it will not immobilize the breaker. However, you can also give your ceiling fan its dedicated circuit, but there is a condition. As with everything, moderation is key. If a ceiling fan is exposed to a dedicated circuit with excessive ampere coverage, it has a high chance of overheating.
Ceiling fans do not need their own circuit. They don’t consume too much energy, so you can pair them with other devices. It does not matter whether it is a washing machine or a TV.
What Size Circuit Breaker do I Need for a Ceiling Fan?
A ceiling fan does not need a circuit breaker, dedicated or otherwise. But if you insist on providing one, you should opt for the least available rating. The reason is that a circuit power that is too high or strong for the ceiling fan will likely damage it over time.
The essence of circuit breakers is to prevent too much current or too little current from damaging your appliance. To avoid defeating the purpose, stick within a reasonable range.
That range should be higher than the ampere consumption of the appliance you are protecting. Remember, moderation is key.
A ceiling fan may not have a dedicated circuit breaker because most options in the market range from 10 to 30 amps, at least. Therefore, it may be challenging to find a breaker that plays around 4 to five amps, which are ideal options for an appliance with 0.5 to 1 amp ratings.
Can I Install a Ceiling Fan on a 20 amp Circuit?
It is not advisable to install a ceiling fan on a 20 amp circuit because the difference in the amperage rating will be too high and therefore defeat the purpose. Most ceiling fans consume less than 1 amp of electrical energy, which means an allowance of 19 amps is too much.
Installing a circuit breaker involves managing the amount of energy that passes through your appliance. Too much, and it overheats.
If you want to use the ceiling fan alone without any other device plugged in, don’t install it on a 20 amp circuit. That is far too much electricity for one device.
On the other hand, if it will share that breaker with another appliance of a higher rating, that is okay.
Does the Ceiling Fan Consume Less Electricity at a Slow Speed?
Yes, the ceiling fan consumes less electricity at a slow speed because it uses a lower voltage. At a slow rate, the appliance may consume 0.25 amperes. Increase the pace, and the electrical current consumption climbs to 0.4 amps. At the highest speed, your device will consume 0.6 amps.
This is the benchmark for smaller ceiling fans, but even the larger ones will consume something within this ballpark.
A ceiling fan does not consume too many electrical currents hourly on a typical day. It is an affordable cooling option. But when you set it to a lower speed, the energy consumption becomes even lower.
If you cannot decide on the type of cooling system to install in your home, know that a ceiling fan is one of the lowest consumers of energy in comparison with most other appliances in the house. You will spend less than $6 if you use it for an average of eight hours daily for an entire year!
