This picture was posted to de.sci.ing.elektrotechnik and I thought it might be interesting for you.
The OP tried to hook up a 2000W heater to the 250V/10A rated receptacle and the result can be seen on the picture. This was not a cheap receptacle but a real expensive one that even once won a design prize. All this happened twice with receptacles of the same brand.
