[QUOTE="kme, post: 74869, member: 113"] [COLOR=red]Pardon? I`m afraid that is incorrect. What you are getting confused with is the earth point; which is from a centre tapping on the transformer.[/COLOR] [COLOR=red]This effectively means that phase and neutral, although 110v apart, are both only 63.5v away from earth. Nothing to do with 2 phases. [/COLOR] [COLOR=red]Does that help??[/COLOR] [COLOR=red]Now the americans don`t use an earth - they have a centre tapped 3 core supply, with the "cold" wire being in the centre.[/COLOR] [COLOR=#ff0000]This provides for 110V to either of the two legs (although both are the same phase - just positive or negative with respect to CT), or 220 between the two "hot" legs.[/COLOR] Can`t find me coat - sorry KME [/QUOTE]
