Well, you can also look at it as a two-phase system with 180 degrees between phases. But since the load is very rarely balanced, so the neutral is normally a current-carrying conductor, it doesn't really meet the criteria of a poly-phase system. -- Regards, John Woodgate, OOO - Own Opinions Only. http://www.jmwa.demon.co.uk After swimming across the Hellespont, I felt like a Hero. ------------------------------------------- This message is from the IEEE EMC Society Product Safety Technical Committee emc-pstc discussion list.
