John, Thanks for your advice about UK. The north of Ireland was said to be 220 Vac. Did you mean she had implemented the harmonised mains voltage while Great Britain has not?

Formally, that 'UK' is not correct. The mainland, Great Britain (GB), had 240 V, but the north of Ireland (NI) had 230 V already. UK = GB + NI. >2008 is the last year to implement it. Did EU really implement it or >was there any further delay in European harmonisation process? I believe that some former '220 V' countries have a concession until 2012. But those standards pre-date the expansion of the EU, and some of the new member states may also have concessions. Products should preferably be designed to accept 198 V to 264 V, or a wider range. -- OOO - Own Opinions Only.
