AFAIK, most mains devices have long accepted 220-240V, such that they can be used around the world (except the US and other 115V countries).
Actually, they can be used in North America too, as house wiring here is 240/120, with 120V between one side and neutral and 240 between the 2 hot wires. Major appliances, such as stoves run on 240V, but it's also used in many outlets where heavy loads are expected. With a duplex outlet, one would be connected to one hot wire and the other to the 2nd, with them both sharing the neutral. It would be a trivial matter to convert one of those to a 240V outlet.
I haven't been following this thread, but saw the above. Do any of the 220-240v mains devices assume one of the legs is ground? A lot of US devices over the last couple decades do. They connect that leg to the outside case of the device. Typical examples are drills / saws / etc. Using a 2-phase US circuit to simulate a 1-phase 220v circuit would be dangerous if there are devices that depend on one of the legs being ground.
