Hehe... The RA90 disks I use on my Vax 3900 are somewhat similar. I can only run one at a
time on the circuit I've got the thing hooked to. And I have to be real careful when I
spin it up, to ensure that the lights and the TV set are both turned off. And even then,
sometimes the thing will run for an hour and then *fump* whirrrrr........ as everything in
the room is plunged into blackness.
But, then again, I've got a lot of other junk on that circuit...

Peripherals,
on the other hand, will vary. If it's
got a couple hefty
disks with it, it might draw a lot more. A couple
large SMD disks can
blow a 15a breaker if you spin them all up at
once.
IIRC, an RA81 disk has an inrush spec of 80 amps for a time
period
measured in seconds.
Ok, so you don't want one of those anyway. :)
