IIRC 11750's only came with the twist lock in the cabinet.
Of course you could yank that off and rewire it in minutes.
I don't think the 11/750 drew 30 amps -- I think it was closer to 20
but DEC always used to go up a bit. I had stuff with 20 amp 115
that drew a lot less than that in real life.
I think the engineers used to take the maximum and max surge at power up
and add a reasonably large caution window for user added loads plugged
in to the power controllers.

Uhhhh, my 11/750 has a standard normal-looking 3
prong standard-outlet
fitting plug.. It never has had a 30A twist-n-lock connector in all the time
I've owned it... Is this a bad thing?
Dunno... both of mine have a power cable that is identical to what we had
on a standard bottom-of-the-rack power distribution box - at least 1/2"
diameter, capped with a twist-n-lock. The 11/730, for example, has an IEC
connector in the back of the PSU, but the 42" cabinet has the same power
cable as the 11/750 coming out the back.
Maybe we just ordered ours with the machine-room power option. Perhaps
there was an "office power" cable option. You can safely pull 15A through
a normal plug (with an appropriately gauged cable attached, of course). By
the time you get to 20A, in North America, one blade rotates 90 degrees to
keep you from sticking it into a 15A outlet (got one of those on the end
of my PDP-11/24). You can buy 20A wall sockets that will fit 15A and 20A
plugs. They have one vertical hole and one T-shaped hole to accomodate either
kind of plug. 30A needs something like the twist-n-lock.
