I followed up on a home inspection report today and opened up a residential 150 Amp 30 ckt panel which contained mostly mini breakers for a total of 34 branch circuits with about 8 full size spaces still open. It was not a "CTL" panel. The home inspection report noted that there was "additional capacity available". The bus diagram on the door only depicted full size breakers (one per space = 30).

Comments, please.
