I'm purchasing a new house and there is a 100 amp main line with a sub panel. The home inspector told me it was maxed out. There is a dryer (can be switched to gas), a stove, a heat pump, and an AC compressor. I'm wondering if theses large appliances' functioning may be affected due to the amount of power being used at once. Are there any other concerns, other than the inability to add anything, like that longed for hot tub!
