old colours

[Lurch]

But with red/yellow/blue there will always be two conductors which need to be sleeved; at least with red/yellow/black only one would need sleeving where a neutral was employed.

All 3 would need sleeving as red and yellow would need to be sleeved brown. Or are we talking old colours, then no. Bit late to ask about getting old colour 6243 changed now!

Only a small point I know, but just something which has often been a niggling little question in the back of my mind. American Romex comes as black/white/red in the 3-core version (2-core being black/white - white is neutral).

argh but if they went the following colours red/brown/black then none would need sleeving sorted! ; )

Phase - brown, neutral - blue. Red - olden days.

I was thinking about before the change. But the same applies to new 6243Y - Why brown/black/gray and not brown/black/blue or brown/gray/blue?

Red - olden days

Not old enough to qualify as "olden days" yet, surely?!

O.K., who voted for red, by the way?

I've seen references to one European country which did actually use red for neutral in the past. I can't remember which though.

Several definitely used red for earth at one time.

Because it was Red/Yellow/Blue so therefore Brown/Black/Grey same as thre phase colours.

Yes, but the question is why use the three phase colors in the first place (old or new colors) when the proportion of 6243Y which is actually used in three-phase applications must be tiny.

Gray = American, Grey = English.

Other than that, I think as above, it's down to what has been adopted as common use and is the cheapest to use as it's the most common. Not sure which came first, this obviously stems back to when PVC cable was invented as I've never seen 3 core in anything other than 3 phase colours, but I'm sure I've seen it an oldish specialist cable book, but not too specialist, might have been a CEF\Doncaster catalogue.

Previous version = olden days.
