Some 2kW power supplies come with weird cables to handle 110V. Slightly annoying for a 230V domestic setup but 3kW from a single socket is fine in Europe. Not totally encouraged of course.
You're talking about 15amp setups in both cases, which is what I was talking about, even including the point that Americans might have to start wiring their offices with 220v just like we currently wire our kitchens and laundry rooms.
