3 phase is supplied with each wire carrying a signal 120 degrees out of phase from the previous one.
neutral is normally grounded at the local substation
earth is supposed to be ground, locally.
phase - what is that supposed to mean? relative to what?
perhaps the USA uses earth and neutral to mean different things? or perhaps 3 phase is different in the US to anywhere else?
or did you mean john fred and mary did a good job of describing the functions?
It *is* nice to be able to actually get 3-phase into the home (if thats what you actually get in the USA). Here we only get 1 phase, albeit at 240V so we dont need another just to run the washer-drier...
My dad actually runs a lathe (full size heavy metalwork lathe) on our standard mains.
