Actually, it used to be this on the Continent (in the UK it was 240V +/- 6%) but a few years ago the nominal voltage in 
the UK and on the Continent was harmonised to 230V +/- 10%.  No actual voltages were changed, but the specification 
was!  :-)  So the voltage can be anwhere from 207 to 253V and still be within specification.

I normally see around 245V in my house, and I have seen it right up to the specified limit of 253V (usually in the early 
hours of the morning).  So if Rikard's transformer is specified for 230V input, it could give 9.9V output with everything is 
within spec.  (Reinforcing the conclusion that a 10V capacitor will not have a nice day! :-)
