Hello TMC member, I recently ordered a model 3 and want to make sure my break can handle the additional breakers. It looks like there are extra slot available. Would it cause any problem if we added new 50 amp breaks to those slots or is there a maximum this panel can handle? Also it seems that all i need to do is have my electrician install 2x50amp breakers. Im very new to this and would like to know exactly what I need tell my electrician.
