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_at_32A/phase, but it runs just fine on 16A/phase.
And our KL-10 sat on this *huge* 410V_at_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...
