I've never been able to use the earth wire as a live return [post 115*] even though it would be so convenient sometimes. Three core and earth was relatively expensive at one time [as I recall] but I just added a single core. I called it drop wire but that's more telephone related I think. I've seen that red sheathing might be used to ID the earth as potentially live [sometimes] but it always seemed to be asking for trouble to me [conscience?] I got a reel recently from a chain supplier. The guy behind the counter insisted they didn't do it even though he had no idea what I was talking about-he was wrong and it was in the catalogue under some title! It's brown to distinguish it from the other three colours.

Just realised their could be one or two new definitions of "con-science" given the suspicion of science itself these days!
