This came from the website: "The Quick 220TM power tap technically uses the fact that 220 / 240 volts AC is supplied to most facilities. The 220 / 240 volts is divided into 110/120 volt circuits for distribution within the building. Using standard 110 / 120 volt outlets and the Quick 220, the user can quickly identify and connect to the separated 110 / 120 volt halves of the original 220 / 240, restoring the 220/240 volt AC option without adding new electrical circuits or wiring to the building."
I'm no electrician but if I read this thing correctly (and tempraiser you would be wise to read it carefully also) without having 240 already in the building the blame thing won't work. And I'm sure some help desk jockey will tell you it will work. Just my 2¢.
