Hi Jean Marie. You wrote: <I'm searching for information concerning the most commonly used three-phase mains line voltage and current ratings in residential and commercial premises around the globe.>
There is an excellent booklet and wall chart available from British Standards THE division, called 'World Electricity Supplies'. It should be available from your local standards vendor. If you have problems do come back to me and I'll give you more information. This document gives information on domestic, commercial and industrial distribution voltages and frequencies, and also type of connection, e.g. Star (Y), delta, open delta, open delta/earthed centre tap, etc. etc. and all the other strange ways of distributing electrical power around a country. Hope that helps, Chris Dupres Surrey, UK.
