I am installing a 240v ductless mini split. My breaker box is full, and I have a separate (hot water) breaker in its own box on its own meter. The main is a 100 amp Westinghouse, the house is 2000 sq ft. 4 beds 2 baths. The house is currently run on an oil furnace.
I see two ways I can approach the situation:
Add a subpanel on a breaker in the main box. Not preferred because I fear blowing the main breaker.
Upgrade the breaker in the hot water box to supply a new subpanel. Preferred because I won't have to be concerned with blowing the main breaker, BUT there is no shutoff between this breaker and the meter, so the meter has to be pulled.
- Are there other plausible options that I am missing?
- Any other reasons why option 1 may be better than option 2?
