Ok, short form (based on experiences with my 11/70):
All of the individual power supplies, fans, etc. in the CPU and assorted
chassis (that I have in my system) are single phase, 120VAC supplies.
(same in my VAX 11/780)
The only part that expects 3-phase power is the 'power controller', and
that is as much for convienence as anything, as internally the power
controller just splits the phases out into three single phase 120VAC circuits.
Now, motors in the large disk drives may be an exeception but I did not
pick up any of those...
The CPU and memory chassis, along with some number of peripherals can be
fed off a 30 amp circuit with some room to spare...
YMMV... B^}
