I would like to know the theoretical loads these circuits might have. For instance, are you running lots of 20 amp circuits, electric heaters, hot water heater, electric range.... or is everything gas, and you just have alot of lighting circuits? I have a feeling this is not about the # of breakers in the panel, but the size of all the conductors and the ampacities flowing through the said breakers. Some more specifics would be nice! Thanx! Brian!
