Do ceiling fans need their own circuit?

Ceiling Fans are Typically Wired on a Shared Circuit with Other Lights and Outlets. Due to the small amount of amperage a ceiling fan does not require a dedicated circuit.

How many amps do attic fans draw?

5 Amps

An attic fan needs up to 5 Amps of service. Up to 10 electrical boxes can be handled by a standard 15-amp home circuit. A 20-amp circuit can handle up to 13 boxes.

How many amps does a house fan pull?



The majority of modern ceiling fans use less than an amp, averaging between 0.5 and 1 amp, depending on the model and the setting. One amp drawn by a ceiling fan is equivalent to about 120 watts. Low settings use less amperage while higher settings use more.

How many fans can be on a 15 amp circuit?

There should be no problem running 4 ceiling fans on a single 15 ampere circuit, though it will depend on what else is on the circuit. Say a 52″ fan is 90-100 watts (at high speed), plus three 60 watt bulbs.

Can I install a ceiling fan on a 20 amp circuit?

Yes, you can install a ceiling fan on a 20 amp circuit.



You can do so along with other appliances, including light, fans, and more. Note that a 20 amp circuit has a load capacity of 2400 watts. So it is designed to work with heavy appliances. You can install multiple ceiling fans on the circuit without any trouble.

What amp switch do I need for a ceiling fan?

Most ceiling fans use less than 1 amp so it’s best to use a control dimmer that’s a little higher, like 1 to 1.5 amps.

What type of wire do I need for a ceiling fan?



Use 14-2 wire, with ground, unless you are tapping into a 20-amp circuit. In this case, all of your wire should be 12-gauge. Run a 14-3 wire with ground from the fan to the switches.

What type of wire is used for ceiling fans?

For most home ceiling fan wiring the electrical box should have either 14 or 12 gauge solid copper wire in it. 14 gauge wire is for 15 amp 120VAC circuits and 12 gauge wire is for 20 amp 120VAC circuits. The copper wires are sheathed in a cable (Romex Cable) and include a black, white and bare copper wire.
