Ok,,,Why??? The answer I will try to get for you at the next meeting with the boy's
as for a guess, which is all i have for now ,
how many 3ph over 250v motors have you seen or heard of that were within 100' of the pool or had or the chance to have any affect if anything went wrong of putting someone in danger,
now this is just a guess.
also,,, we do in our have a book which contains the in-depth findings for or against changes made or not made in the NEC.
I will check there too , someplace there is an answer to the "Why's?"
