  Our 3650's (4Mword memory, 8 bit color, 2 760Mbyte SMD drives) consume
 9.2 Amps continuously and startup with a very short 17 amp spike.  It
 is configured from Symbolics with a 20Amp NEMA twist-lock plug.  It
 dissipates about 5000 BTU's of heat per hour (about the heat of a 1500 Watt
 hair dryer).  

  I never measured the heat or current from our XL-1200 (4Mword memory with
 a photon board) but it is less than our 3650's.  The power plug on the back
 is a standard 15amp wall outlet connector and the sticker says it can
 consume 12amps.  I would assume that is worst case if all VME slots and
 disks are installed.
