Wiring a subpanel from an existing 200/240 outlet
I have an existing 220/240v outlet in my attached garage. Can I wire a subpanel off of that so that I can add a heater and a couple of additional 220 outlets for when the heater is not in use? If so, would I use 10/2 throughout and then what would be the recommended Amp load for the breaker(s) considering that the heater might be as large as a 10,000W unit? Also, I believe that the breaker for the existing outlet is a 30A double pull in the main panel. Is that sufficient?
Thanks for the help!!
