All of the EEC is standardised at 230v mains, however, the UK doesn't use the same tolerance as the rest of Europe - so UK mains can be 240v and still be within permissible limits. No where in the EEC uses 220v anymore, so you shouldn't supply 220v equipment to any EEC countries. -- Nigel. /--------------------------------------------------------------\ | Nigel Goodwin | Internet : nigelg@lpilsley.co.uk | | Lower Pilsley | Web Page : http://www.lpilsley.co.uk | | Chesterfield | Official site for Shin Ki and New Spirit | | England | Ju Jitsu | \--------------------------------------------------------------/ -- http://www.piclist.com hint: The PICList is archived three different ways.
