First time user. In the process of finishing off my detached 32x48 shed and in the process of pulling wire. Looking to install 2 Industrial ceiling fans that will be controlled by 1 switch (capable of running multiple fans). The fans will not have a light, but looking to control both in tandem, controlling the speed and direction. This particular circuit will be 15amp, with power running into switch, to fans. How many wires will I need to run from switch to and between fans--14/3 or 14/2 or other? Thanks for your input.
