I have two boxes at home that will not power off of a normal wall socket.
My recently-aquired DEC 4000 has a 20A NEMA plug (blades are like (- |)
not (| |), and my VAX 8200 has a 30A Twist-n-Lock.

Long ago, I stole the dual breaker slot from the electric stove (I have a
gas stove; the kitchen is plumbed for either) and replaced it with two
singles. One single is a 30A that runs to a Twist-n-Lock in a box next
to the breaker panel. To power the Alpha, I just unplugged everything
from the power sequencer in the BA32 cabinet (the other end of that 30A
cable) and plugged the Alpha into it (the sequencer _has_ 20A 110V
plugs (-| |) I just run one CPU or the other. If I need to run both,
I suppose I'll go to Lowes and get a 20A duplex outlet and wire it
into its own 20A breaker (not off a branch circuit).

My house only has a 100A feed from the pole - it's a 90-year-old house
that used to have a printing press in the garage, so the garage took
100A from the pole, and the house took 100A from the pole. The garage
was torn down before I bought the place :-( but it had its own electric
meter. Now it's a blank plate, but the house is still stuck with 100A
unless I cared to activate (and fully wire) the second meter.

I need a gas dryer now. :-)
