I'm cold and in desperate need!! Please help!!!!
I have a 3600 watt 240v window air conditioner in the house that uses a nema 6-15 plug and receptacle. I'm pretty sure that it is wired into two 20 amp breakers. I am looking to buy a 240v garage heater to use inside my house to supplement the 120v electric heaters that I already have. I can't plug in any more of the 120v heaters without tripping the breakers. I found a garage heater that has a three way switch that does 3000/4000/5000 watts. The data sheet on the 3000 watt switch says it draws 12.5 amps. Could I wire up this heater to run at least on 3000w (low) and draw the 12.5 amps without any problems? Also should I use 10/3 wire to connect it? Link to the heater. Thanks for any help! https://www.manualslib.com/manual/2031837/Ken-Brown-Kbh-5000w.html?page=4#manual
