Some here seem to think that we are amateurs--if not

electrical engineer on our team very carefully located three
phase-isolated outlets for us, working from the power panel outwards,
before we did anything else. We tested the plug box for phase
isolation before connecting either VAX, and we had every internal
breaker off and every internal plug disconnected for several hours
while we checked the power coming through the main breaker.
I'll assume that I'm one of those people, and I'm sorry if I came off
that way, I definitely do not feel that you and your group (PDPplanet)
are idiots, I was trying to explain things for the benefit of other
readers (also, Ian King made no mention of what group this was with,
and seemed to me that he was missing the particular point I was making
in my replies, which is my excuse for belaboring the points I was
trying to make :).
