I remember a big plug rated at probably at least 50 amps. One suggestion would be to check the name plates
either on the chassis
near the power inlets, or on the power supplies. You might also use
the power cable and plug dimensions as a guideline; find the current
rating of the cable used for the power inlet. That should be somewhat
over the actual amount needed but not massively so -- power syhstem
designers don't usually overdesign cables by large margins.
Yes, they do.
The VAX8600 was targeted at large IBM sites, so they put in an oversized
power cable and receptacle, that was the same as for the IBM equipment
they planned to replace.
So the 8650 I have here have a cable and receptacle specified for
410V@32A/phase, but it runs just fine on 16A/phase.
And our KL-10 sat on this *huge* 410V@63A/phase thingie. That receptacle
was just large enough to be silly. And the power cable is not something
you carry around in your hand...
