Let me retract that, it appears that the NA breakers are full sized double
pole, and the NC are half sized double pole. My guess is that they don't
make half sized double pole breakers in the larger sizes, like 100 amp. In
any event the 2/100 NA will fit in the panel in a location where you'd
install four full size single pole breakers, two on each side of the buss
