Ceiling fans appear to be everywhere. The strange thing is when we have non-functional cooling fans, we don’t think about them. But, once warm weather arrives, then we notice their presence. Do you ever wonder how many ceiling fans you have and how much electricity the average ceiling fan set uses?
The fan’s speed and size determine the amperage used by a ceiling fan. It typically consumes less than one amp when a ceiling fan is turned on. Low-power settings consume less amps than medium- and high-power levels.
For example, an average ceiling fan on a low-speed 120-volt ceiling fan, for example, uses 0.17 amps. A low setting draws 0.58 amps, whereas a high setting draws 0.65 amps. (Learn How Often To Run Exhaust Fan In Grow Tent)
How Many Ceiling Fans Can Be On A 15 Amp Circuit?
Ceiling fans consume very little electricity and are economical to run compared to electric heaters and air conditioners that use between 10 and 20 amps.
However, one area often overlooked is that of fan startup. While it doesn’t take too long, if you have air conditioning running, the spike from the fan motor kicking in could be enough to trip the breaker of your AC units.
In our guide, you can find out more about your ceiling fan amp draw and how they can affect the running of heavy-duty appliances when they start up.
By the end, you’ll know how many ceiling fan amps you’ll have on a circuit. You’ll also see how you can adjust these away from higher settings with an adjustable switch to consume less electricity and make a big difference with your electric bill.
How many amps does a normal ceiling fan draw?
A ceiling fan consumes around 120 watts each amp it draws. The lower the setting, the less amperage is used, whereas the higher the level, the more amperage is used. For example, an average ceiling fan set on low speed uses about 0.25 amp, on medium speed about 0.4 amp, and high speed about 0.6 amp.
Running four ceiling fans on a single 15-ampere circuit should be possible, albeit it will depend on what else is on the circuit.
A 52″ fan at high speed consumes 90-100 watts and comprises three 60 watt lights. Therefore, each fixture should be around 280 watts.
An average ceiling fan or box fan runs using less electricity than an AC unit, according to research. As a result, you can continue to use a ceiling fan to keep your space cool.
Depending on the power settings and model type, a typical ceiling fan consumes 15 to 90 watts of electricity. (Learn How To Balance A Ceiling Fan)
You can leave your fan on for up to ten hours without risking damage to the coils or the ceiling. Your box fan will also consume less power than an AC compressor for a shorter duration.
You may ask, how does an amp compare to a watt?
Based on a 120V power source voltage, one amp is equal to 120 watts; hence 0.5 amps is equal to 60 watts.
This method of calculating and comparing electricity is always the same. For example, if the voltage is reduced to 110 volts, one amp equals .54 amps, and so on.
What does a typical ceiling fan draw, or how many amps do ceiling fans use?
A ceiling fan uses around 120 watts for each one amp it draws. So the lower the setting, the less amperage is used, whereas the higher settings use more.
An average ceiling fan uses roughly 0.25 amp, on medium speed about 0.4 amp, and high speed about 0.6 amp.
Ask how many LED lights you can add to a 15 amp circuit. An LED bulb typically draws around 10 watts (give the same amount of light as a 60-watt bulb), so you are safe up to around 30 lights before you reach maximum power use.
How Many Amps Does a 52 Inch Ceiling Fan Pull?
The solution is. 72 volts. Using the Ceiling Fan Amp Use Table, you may determine that a 52-inch-diameter ceiling fan will use 0.72 amps.
|Ceiling Fan Size (in diameter)||Amps|
|24 inch||0.34 amps|
|30 inch||0.40 amps|
|36 inch||0.46 amps|
|42 inch||0.54 amps|
|48 inch||0.63 amps|
|52 inch||0.74 amps|
|56 inch||0.85 amps|
|60 inch||1.00 amps|
|72 inch||1.50 amps|
Ceiling fans come in a size of sizes. For example, a domestic ceiling fan with a diameter of 24 inches is available, and other fans with a diameter of 72 inches or even more are also accessible.
The more amperage an electric motor on a fan requires, the bigger it is. A typical ceiling fan uses less than one amp of electricity, as seen in the table above. Industrial ceiling fans are substantially more expensive and larger than standard ceiling fans.
An industrial ceiling fan can cost up to $1000 and utilize anywhere from one to six amps, depending on the engine and blade size. Industrial fan blades can reach lengths of up to ten feet.
The Hunter Ceiling Fan is a prominent and well-known brand of ceiling fans.
The Hunter ceiling fan uses less than one amp of power.
Does A Ceiling Fan Need Its Own Circuit?
The cooling fan relay is the relay that controls the cooling fans if they are linked to AC units. When specific parameters are met, they activate the relay and deliver power to the fans.
Usually, a faulty cooling fan relay can produce symptoms.
The first symptom of a failing cooling fan relay is running hot or overheating, especially fan motors.
Ceiling fans run for long periods, and cooling fans that do not function or non-functional cooling fans are common symptoms of an issue with your cooling fan relay. (Learn How To Hang Plants From Ceiling)
Cooling fans stay on is also an issue as this means the electric fans are using electric. Depending on the fan speed, it could cause further damage and use more electrical power.
How Many Fans Can You Run On A 20 Amp Breaker?
Any high draw component with a large draw requires the usage of a relay. As a safety issue, fan motors, particularly a parallel pair, are desirable in case of a failing cooling fan relay.
A relay coil only draws an amp or an amp and a half, whereas a motor will draw 17 amps and spike on startup or if the rotor locks.
When a normal ceiling fan is turned on, it consumes 75 watts of electricity.
However, according to code, a circuit with 15 amps can only use 80% of its breaker. As a result, it will provide around 1200 watts of usable current.
We can see that a 15 amp circuit can serve around 16 ceiling fans when these parameters are considered. Providing the circuit isn’t connected to anything else, such as your air conditioner.
As a result, it’s only required if you’re putting ceiling fans in a large space. Otherwise, a 15 amp circuit will be ineffective.
A 20 amp circuit on the other side can support up to 20 ceiling fans. Besides this, on your 20 amp circuit, you can use 12 gauge wire for the wiring.
To understand how many watts a typical ceiling fan uses (it doesn’t need to be on a 20 amp circuit), you’ll find a typical ceiling fan consumes anywhere from 10 to 120 watts. It varies based on brand, model, condition, speed settings, and other factors.
At moderate settings, a typical fan will use roughly 75 watts.
The average ceiling fan states that 16 watts are needed for speed 1 or the low settings. Speed 2 on a regular fan uses 27 to 30 watts.
An average fan uses 45 watts at medium speed and 55 watts at top speed. On average, a ceiling fan that runs at a speed five or high setting consumes 75 watts.
Ceiling fans do not require any additional wiring. The wiring system is like a typical light installation, and ceiling fan amperage is no higher than many other devices or has a higher electrical current than running multiple light bulbs.
A standard 12-2 wire can wire a ceiling fan. Also, if you’re installing an adjustable switch, a 12-3 wire would be great.
For a ceiling fan, 14-gauge wire can be used. However, you must use 14-gauge wire with the ground to comply with the rule for a modern wiring system. A 14-inch gauge wire can carry enough electricity to power a conventional ceiling fan.
Even if you want to use it to power a giant ceiling fan, it’ll work. Ceiling fans use relatively little electric in comparison, so you don’t need any extra wiring. While a 12-2 wire is ideal, a 14 gauge wire will work fine for a ceiling fan.
