..genau !

Zitat:Here's the redneck way.  There's already 240V in your house so what you do is get and extension cord and a multimeter.  Pick an outlet in the room you are using.  Plug the extension cord into an outlet in another room.  Measure the voltage from hot to hot of the extension cord and the outlet.  If you get 0Vac move the extension cord to another outlet.  If you get 120Vac you are measuring hot to neutral and are doing it wrong.  If you get 240Vac you are good because you have found an outlet on the other phase.  Make a box that takes in 2 IEC cables and outputs to a single 240Vac plug.  Connect each of the hots from the IEC connectors to one side of the 240Vac plug.  Plug the box into the outlet and the extension cord.  You now have a 240Vac outlet.
