How do, folks? Please bear with me, this being my first post. If my question has already been answered somewhere that I couldn't find during my searches, please be so good as to direct me there.
OK, enough preliminaries. Here is my problem. The house which I just bought has a 200-amp service. I hope to add a 20-amp heater in the garage, and a 20-amp heater/AC in the 3-season porch. Sadly, the breaker box is maxed out (I'm exaggerating, but it seems like every outlet and light in the house has its own dedicated breaker.) There is a 20-amp circuit feeding the stove/oven. I figure I can pull this and put it in my soon-to-be-added subpanel, along with the two 20-amp heater thingies, for a total of (just a sec, let me get my calculator...) 60 amps of potential load. When it gets cold (as it is wont to do here in Iowa for about 6 months a year) both of the heaters are likely to be running together much of the time. My question is this: Will my breaker and subpanel need to be rated for at least 60 amps, or will a 50 be sufficient?
