sparky,

I'm mainly just curious about the use of mini breakers in a non-CTL panel and how many breakers can properly be installed. I'm thinking only 30 full size(no minis). Someone could conceivably install 60 mini breakers in this panel.
The reason that I was called in was because the home inspector "recommended the service be upgraded to 200 amp". What his recommendation is based on, I haven't a clue. He didn't say. Now the buyers want a 200 amp upgrade. This was immediately after his remark that "there was additional capadity available". This, I assume was due to the 8 available spaces. I did a calculation for existing dwellings and determined that about 115 amps is adequate for this size home.
