Have you ever thought about your ceiling fan amp draw and how much electricity is used by all the ceiling fans installed in your house or office? Well if you are interested in such information, you are at the right place as we are going to explore this topic in detail through this article.

There are a number of factors concerning ceiling fan amp draw, keep reading to explore more.

Ceiling Fan Amp Draw - Expensive Or Economical

Ceiling fans are not so expensive in terms of electricity consumption. These electronic devices are quite economical when compared to other similar electrical products like heaters and air conditioners. But we would like to point out an important aspect in this regard which is the starting point of your fan.

To understand its electric consumption at the starting point, we will give you a relatable example. If your Ac is already running then turning your fan on will cause the breaker of your AC unit to trip right away.

Ceiling Fan Amp Draw

Amount Of Amps Required By Your Ceiling Fan

We usually don't use ceiling fans until the weather turns from cold to warm, but the question is, how much electricity does a typical ceiling fan use? It all depends on the speed at which you are using it and the diameter of the ceiling fan.

A regular ceiling fan usually takes less than one amp when starting. If you run the fan on low settings, it will use less power because when set to high settings, it will use more power than at low settings.

Ceiling Fan Light Bulb Size: Which One Suits You Best
You might get confused while thinking of changing or replacing ceiling fan light bulbs due to the different sizes in which they are available out there in abundance. our research team has worked for a long or on your behalf in order to find out the solution to your problem.

Let's say that a regular 120-volt ceiling fan running at low speed will draw 0.17 amps when starting. Depending on the settings, at low settings, it will draw 0.58 amps, while at high settings, it will draw 0.65 amps which is slightly higher than at low settings.

Typical Fan And Amps Usage

In terms of each amps draw, a typical fan can consume about 120 watts on each. So if you operate it at lower settings it will draw fewer amps and if you go for high settings it will draw a high value of amps.

Another factor that affects the use of amps is the speed at which you run the fan. For example, a typical fan uses about 0.25 amps at average speed, when it runs at normal speed, it will use about 0.4 amps while at high speed it will draw 0.6 amps.

Ceiling Fan Size And Amp Usage

In general, ceiling fans are directly related to the size of the fan. You can easily determine the amp drawn through a ceiling fan if you know its exact diameter. Let's understand this by looking at some examples of different-sized ceiling fans and their amps drawn.

Should A Ceiling Fan Wobble? All You Need To Know
Installing a ceiling fan has never been an easy activity, especially for those who are just doing this as a home task. But the real issue sometimes waits ahead when after a long effort your ceiling fan is wobbling in front of you with an ironic smile. This article is

Diameter of


A regular ceiling fan with a diameter of 24-inches will draw 0.34 amps at average speed.


A regular fan with a diameter of 30-inches will draw 0.40 amps at average speed.


A regular ceiling fan with a diameter of 36-inches will draw 0.46 amps at an average speed.


A regular ceiling fan with a diameter of 40-inches will draw 0.54 amps at an average speed.


A regular ceiling fan with a diameter of 48-inches will draw 0.63 amps at an average speed.

Mostly Use

Typically, Most domestic ceiling fans come with a range of diameters between 24 inches and to 72-inches.

Plugging A Fan Into An Inverter

Using a small DC battery you cannot directly power the ceiling fan or other household appliances. You can power them directly from the battery source by using an inverter or converter that will directly convert the DC voltage to AC voltage. Let’s say you can convert a 12-volt DC current into a 110-120 volt AC current by using an inverter.

Frequently Asked Questions

How many ceiling fans can be on a 15 amp circuit?

If you run four ceiling fans on the same 15 amp circuit, it's no big deal, and chances are the load will break the circuit. It all depends on what else is running on the circuit, let's say a 52-inch fan is running at 90-100 watts, and three 60-watt bulbs put the same load as 4 ceiling fans can do.

How many amps does a 52-inch ceiling fan pull?

According to the research conducted by our team, a ceiling fan with a diameter of 52-inches will consume 0.72 amps.

How many ceiling fans can I run on a 20-amp circuit?

Typically, you can run 20 ceiling fans on a 20-amp circuit because most ceiling fans are between 60 and 80 watts and they use less than an amp. On average they use between 0.5 to 1 depending on the model and settings.

For better understanding, one amp used by a ceiling fan is equal to about 120 watts. If you run a ceiling fan on low settings it will use less amperage and when it runs on high settings it will use more amperage.

How long will a 12-volt battery run a fan?

If you want to calculate the exact run time of a 12-volt fan, first you need to find the amps used by the fan. Suppose you are using a battery that has a capacity of 12-amps. Then a 12-volt fan will run for about 12 hours. Because a typical 12-volt ceiling fan uses 1 amp on an hourly basis.

Final Words

We hope this article has cleared up all your questions about how many amps a ceiling fan use. To explain this we have discussed in detail the concept of amps, volts, and total fan power draw.

We also provide you with typical examples of the main types of floor fans ceiling fans and table fans and their usage amps daily and hourly basis. In the end, we are very happy to have answered some of your relatable questions.10
