Hi all,
I need an electrical wizard to advise me here. I am installing a new hot air wood furnace next to an existing electrical furnace. I have run the 20 amp cable along the basement ceiling ok and now I need to drop down to the furnace. I want to add a cut-off switch so that I can isolate the thing in an emergency.
Can I put this switch on the plenum? In a metal box? The other furnace has a small breaker box on its plenum with 3 breakers inside, so I can't se why I should not be able to do this. I have used standard orange 10-gauge romex cable.
Plenum temp is set typically to turn on fan at 170, and will open an emergency heat dump at 200 in case of a problem.
Thanks!
Dean
