Last time I tried to search for something like this on our DEC 7000, I
ended up with <something>. Yes, I can't remember if I thought it was
possible or not. :-) It do looks like it's more modern power curcuit
technology than the old VAX 6k beasts. But, you are probably very right
about that power rail.
First time ever I've seen automatic fuses on a three-phase machine, I
think.
