Yes I am curious if it is possible to wire a thermostat. Where power could be supplied from a wall outlet through a 3 prong, and supply power through a seprate 3 prong.
Thank you for any help

Thermostats are available for that purpose. They are cheaper than you can make one for. Check on the net for availability and price.

I don't think so as I already have the two thermostats, wire and plugs, just need the know how now.
If there is a website someone could direct me to it would be much help.
Thank you for your time.

Break the hot leg with the thermostat and make sure you ground the case if the thermostat has a metal case.

What about a 24 volt transformer?

Use a line voltage stat.

But, you can as I did, wired a transformer, a relay or a "Fan Center" in a J-Box. The t-stat is under my workbench. It uses a 3 prong plug and a convienice outlet to control a space heater. The heater control acts as a high limit and also contains the tip switch.

You did not mention the application.
