Two Industrial Ceiling Fans on One Switch

[Thedailyb]

Hello,

I am planning on installing two industrial fans in my pole barn. Both fans would be controlled by the same switch. I plan on having an electrician/inspector check the work before it is plugged into panel but I am hoping to save money and do most of the work myself...

Here are some facts that might help you understand:

-Here is a link to the wiring diagram from the manufacturer of the fans and the switch: https://www.canarm.com/assets/product/documents/M0062-CNFRMC5-060607.pdf
-I have a 100 amp subpanel in barn with lots of room left over.
-I live in Michigan in case the code for my questions might depend on my location.
-The fan shows five wires coming from it (including the ground).

Here are my questions (please bear with me as I am not an electrician):

-Do I connect the fans together and then run a connection to the switch? Or would I run separate connections from each fan to the switch? The second choice would require more wiring.

-What type of wire would I use to connect the fans together (via the five wires)? I live in Michigan if that impacts the code. Could I use a couple 12/2 romex and mark the wires carefully? (This would leave me with an extra ground wire that would not be used.). Or should I use something thinner so that it is cheaper and easier to fit into junction boxes?

-I am planning on using a 20amp breaker in the panel box? Is this what you’d recommend?

Thanks in advance for any help that you could provide!

@Thedailyb welcome to the forum and yes you can tie both fans together and run 12/3 Romex to your light switch. You stated that you had 2 industrial fans and one has 5 wires what about the other fan. I need to know the HP, the voltage because they could be multi tap fans, also I need to know are they single phase or 3 phase, then the full load current before I can advise you any more till we get the proper info. Your link is not working

That link is to a 120v single phase fan speed controller hence all the wires from the fan. It is only for the speed controller with no info on the fan motor power.

Thanks for the info Westward I guess we will see if he responds

It is also reversible as well as speed controller.

When he said industrial fan is what got my attention the most. You and I both that they can be multi tapped and with the speed controller and reversible to. Thanks for the info

I told you yesterday that you need 12/2 with a ground romex and you need to use that ground wire on both ends
