Yes, it was the 414V label I had in mind. Every nominal voltage label I've seen here before says 415V. If you work it out, the exact conversion is 240 * SQRT(3) = 415.69V.

I suppose that eventually we'll start seeing labels adapted to the new Euro-voltage of 230V, so I wonder whether they'll say 400V or 398V ?

Trumpy,
Yes, the 0800 code here indicates toll free. There are other toll-free codes as well, such as 0808, just as America added 888 etc. to their original 800 code.
