My copy of the UK wiring regulations is rather old. Can anyone = provide more up-to-date information?) UK was 240 but is now officially 230 (EU harmonisation). Normal = domestic appliances use 230V. Standard 3-pin socket outlets are limited = to 13A. For higher current, such as for an electric cooker, a separate = fixed feed - not via a plug and socket - is required. A clothes dryer = would be designed to take a maximum of not more than 13A at 230V. This is all single phase. Very occasionally you may find a 3 phase = supply in the home, but the supply companies don't like providing it. = If I remember correctly, additional regulations apply for 3 phase Such = supplies are usually four wire (3 phases and neutral) with 240 from each = phase to neutral and 415 between phases.=20 John F5VLF/G3PAI PS France was 220 but is now officially 230.
