So that's 3P and relative PD in aphase conductors explained, now why is orange jam called marmalade?

Nothing to do with Mary queen of scots suffering sea-sickness---apparantly.

Good answers wayne and raylewis ! so how does split phase work ? 460-480v lol only joking ! southern electric use this alot in remote areas like farms etc saves expence sending 3 phases across fields etc !

Split Phase, 460/480v Single hot wire and N dumped into a tranny and same voltage out with a center tap = 230/240, N, 230/240

I was under the impression that it was 2 "hots" in and locally sourced neutral(earth)for your centre tap out.giving 230 out or 460 if reqd(eg welder) But I bow to your supierior knowledge.

I wouldn't disagree with you on that, it works both ways. In the U.S.also it's 2 hots and a nail in the ground for N/E. On this side of the pond both systems have been used.(I've met them) I'm not sure what the current GB standard is or if it's different for different suppliers.
