Thermostat Wiring

I have an attic exhaust fan thermostat and I was wondering if I could wire it to a receptacle to control a plug-in fan. I would like for it to come on and off when it is set to a certain temperature. This will be used in a small outside building.

No issue with wiring the thermostatic switch to a receptacle. Some attic fans are wired like that.

If the thermostat isn't in the same box as the receptacle, I would suggest adding a note on the cover plate stating that it's "Thermostat Controlled" so the next homeowner won't be confused as to why it only sometimes works.

The thermostat has two wires. It just interrupts the black wire to the receptacle.
Will this be a portable set-up ?
There are several different styles of stats so if you post a picture we can help you with the set up.
How to insert pictures.

I hope it will be permanent.

Does this look good?


Is the resistor good?

Since that is it's own junction box you can mount that to the wall. You can run power thru it or use a two wire cable to connect to an existing receptacle. The grounds get attached to the metal box for safety. Not shown in diagram.

That device on the thermostat is a high heat safety fuse. In the event of a fire.... it will blow open permanently shutting off the fan.

The top diagram is power passing thru.
The bottom diagram is a two wire cable to the receptacle. It's recommended to tape or color the wire a different color from white so that it's not confused as a neutral. The open KO needs to be sealed.
