I cannot find the requirement. I just had a city engineer mandate it with the words "It is in the NEC". I thought I read someplace it is a good idea, but that is not a requirement. I forget almost everything I read. I searched the NEC for "growth" - no words found, "allowance" several times but never relative, "service size" one time....then I thought, someone in here knows the answer.
