Can you wire two ceiling fans on one switch?

Dave’s Guide to Home Electrical Wiring:

»You Can Avoid Costly Mistakes!« Here’s How to Do It: Wire It Right with the help of my Illustrated Wiring Book Great for any Home Wiring Project.

1. Powered Ceiling Fan and/or Light Without Any Switches (NoSwitches)

We recommend this method when you simply cannot run a switch into the room. It does require that you have the ability to bring power directly to the fan from a nearby location. It’s certainly an acceptable wiring method and the fans all come with pull string switches to control the fans and light kits. Wiring this type of electrical connection looks like this:

As you can see, this simple connection feeds power to both the fan and (optional) light kit. The ground and neutral wires simply get tied together as you’d expect. The power for the fan motor will typically be black, while most modern-day fans also have a separate blue wire that supplies power to the lights. It’s important to connect this wire even if you don’t plan on using a light kit as it gives the homeowner the opportunity to add one later on without having to remove and rewire the fan from above.

Step 3

Buy cable appropriate for the type of circuit. A 20-amp circuit requires 12-gauge cable, while a 15-amp circuit requires cable no smaller than 14-gauge.

5. Switching the Lightand Fan from the Same Switch with Power at the Switch (Single switch)

This is identical to situation #3 above. However we wanted to outline the wiring differences when the power is actually at the switch instead of in the ceiling. We find this method is encountered in roughly fifty percent of the time in older homes. It especially occurs when electrical wiring originated in the crawl space. Additionally, there is a sort of clean-ness to this method.

It also offers two helpful advantages. First, the wires are consistent. You have no re-labeling of neutral wires. Secondly, this method of wiring makes swapping out ceiling fans easy. Cutting power at the switch eliminates all power to the ceiling box. Note that we still recommend deactivating the breaker and checking your wires with a voltmeter, but it’s worth noting nonetheless.

Mount the bracket

Mount the fan bracket according to the instructions that came with your fan. Then slide the fan into the bracket to get it ready for wiring.

Wire a ceiling fan with light to one switch: In conclusion

That’s how you wire a ceiling fan with light to one switch. Now when you turn on your light switch, the fan will have power. To turn the fan and lights off separately, use the pull chains on the fan.
