However... it just ocurred to me that even though I
did that, I
still have some sort of a "connection" through the main power
lines (3x 500VAC @ 48A/ea) here, so, if an old 11/23 in a BA23
goes smokey on me, it still could kill my (quite expensive)
production network stuff through the power system.
Does anyone have (serious) ideas on how to fix this (short of
requesting three separated power lines from the utilities.. they
have a hard time dealing with me as it is ;-)
I think you are overreating. Keep the vintage stuff on a seperate breaker
from the production stuff. If the PDP-11/23 "goes
boom", the smaller
breaker will trip first, and the other breakers, including
the main one,
will still be closed and happy. The other circuits and machines may notice
a small dip in the power for a fraction of a second, but they could
probably weather it.
UPSs, surge protectors and a big old Sola isolation/regulating transformer
would also be nice, but overkill.
