>>>It is a code violation to have a 225A main serving a 300A distribution breaker, since they can never be coordinated.<<<

i know i'm going to sound stupid, but where does it say that? 240.12 tlaks about coordination for orderly shutdown, 110.10 says to cordinate to rpotect equipment. but i dont see why a smaller ocpd cant protect larger ocpd's or equipment. inconvenient to the user, but is it a violation? thanks
