You would have to check your local codes, but we have three separate

So how are the service entrance conductors sized? If the ampacity of
the service conductors is less than the sum of the ratings of the main
breakers on the three main panels, then the only thing protecting the
service conductors from overcurrent is the statistical unlikelihood of
all three services drawing maximum power simultaneously?
