First time I have posted anything, but use the forums a lot to find most answers to my questions. I mostly do single family homes, but this one obviously is not. I plan on replacing these meters and panels with a gutter box, and adding 2 meter main 100 amp panels. My question is the sizing of the service entrance conductors. Does it matter what size they are, even if they are not even rated for 100 amps, since I will not be adding any load to the building? As of right now i have no clue what size the wires are, but I want to be prepared. I appreciate all the input I can get. Thank you in advance.
