Bob, we are on the same page here. I meant 200 for the building. Your calc would let you use 100 (the NEC minimum)

I am not sure how EUSERC might apply. We don't do that here.
Tesla seems to be saying you would need 125a per unit and that does sound silly in your circumstance.

As to the idea of a EUSERC forum, if we have enough people affected, why not.
