Aldav, that is just not correct. Period.
First of all, the equipment used for a 400 amp service is, as the PoCo considers it, really only for a 360 amp service. If the calculated load is higher than 320 amps, they will want to replace the CT used to meter the power consumption with one of a higher rating.
Likewise, they will also look at their transformers; it is quite possible that the transformers are already being used at capacity, and will have to be replaced.
Just a few months ago, I was in this situation with our PoCo. The Troubleman raised his concerns, and a two-hour shut-down became a five-day shut-down. On Day 5, I had at least six levels of PoCo management decend on the jobsite; their "top dog," after reviewing the site, got all wound up, and started to give his standard speach to me about "you guys who don't clear things with us." He looked truly disappointed when I produced the paper where the PoCo had, in fact, signed off on the job!
