I'm sure they must have made a 220VAC model, but I've
only ever seen
the 110VAC type (sample size > 2)

take a meter to the wall plug?

And my VAX-11/750 runs on 220/240 VAC 50 Hz.
Although at the moment, the mains fuse in the house blows when
I turn the key :-( In my previous home the machine ran well on
a 16 Amps group. I have no clue yet as to why it blows the fuse
of the 16 Amps group after the move to this house.

Did you try a slow fuse ?
Or B-automaat problably the turn on current is to high. Slow fuses are been used for
welding equipment with high turn-on currents.

You may have lots of wire (and some wire connections which are corroded,
thus with lots of resistance) between your main distribuition point and your
wall socket. What about you run a direct wire (of correct size) from the
distribuition point to the Vax? :o)

You probably have to change the automatic fuse and replace it with one
that has a C characteristic instead of B. It's possible that you have a
cheap or crappy fuse that doesn't really follow the specs.

Thanks for the responses.
Yeah, I already figured that the home fuse of that group has a fast
action. I planned to swap the automatic fuse with either a slow-blow
standard fuse, or an automatic fuse with slower switch off time.
But I just never got to do that ... and now the garage so so filled
with goodies that I would have to move a lot of stuff just to get
the wall plug picked up. My wife calls it junk, but that's just a
matter of perspective.
One day I will do the home fuse swap experiment ... I can not believe
the VAX has suffered from the journey from the old house to the new
house. I rolled it just 5 meters, into the truck using a hydraulic
tailgate lift, and after a trip of 30 km (driving at sensible speed)
unloaded and rolled another 5 meters. I can not believe that the
wiring in the VAX is that bad, that really minor "shocks" will cause
some full short circuit condition.
Waiting for better times, then I will get the VAX running again!

As is mine, as were the two I ran ~20yrs ago.

We ran ours on 208V, I think we had 4MB; we used a Fuji Eagle drive
and a
CDC cartridge drive for disks and a Cipher
streamer for tape. It
worked
