My question is regarding 690.64 I understand the concept of this calculation concerning putting breakers in the house panel or doing a line side tap if the calculation works out over the rating of the bus bar in the branch circuit main panel. My question is does my AC combiner panel also have to be sized the same way. so if i have two 30 amp breakers and 60 main in a 125 amp combiner panel do I have to up the size to 150 or can I leave the 125 amp combiner panel the same as long as i do a Line side tap to feed this panel.
Thanks
