White was neutral if you go back far enough.

And green was live!

I don't go that far back but I seem to recall working on installations as a dogsbody in the early eighties and the existing 3 phases were red, white and blue with neutral being black?

Red YELLOW and Blue with Black as the N, or are you extracting the urine?

Nope I wasn't trying to get a rise from anyone, I genuinely recall these colour sequences.

Nah, even a youngster like me has come across the occasional but of red white and blue

Well if that's true and I'm not doubting you, it's a new one on me, you sure it wasn't yellow but a bit faded? or maybe the light was bad and you need to visit Spec Savers, oh they weren't about, or are you extracting it as well ? lol

Oh yes just searched an old IET forum and found it under pre 1950s wiring.

No I'm being serious, Tony had some great pictures of an old red white and blue open busbar installation which he posted up here when he was still a member.

The times I have come across it have been old imperial three-core insulated and sheathed cables (no earth)

Google 1950s wiring Regulations and click on IET forums-cable ages.

i thought white black and green are the American cable colours
And i have seen the old red white and blue three phase colours , and imo the best choice of colours, easy to see what each phase is in the dark.
