One other question I forgot to put in my other question/thread:
this building is a fire restoration return to service permit. I have an existing 200 amp service being fed with 4/0 aluminum which is only good for 180 amps. This is a comericial zoned building, cannonot use resi table 316. ? (Dont Have code book) Does 240.4? Next size up rule make it complient, as long as calculated load is below 180 amps?
thanks
