Colour code the switch lines in lighting circuit

[JohnW2]

Good to see you, and I hope that all is well with you and yours.

However John, the brown sleeve on the blue conductor indicates this is functionally aLine conductor. Just look at 514.3.1(i) followed through to 514.4.4.

It does, and I've just acknowledged that, despite what has been said (seemingly incorrectly, by myself and others) in discussion, there does not appear to be any "except when there is no possibility of confusion" caveat, except (which doesn't seem to make much sense) possibly at the interface between old and new-coloured conductors.

FYI, if not present, I'm with RF and code it C3.

I don't think that anyone has disagreed with that (except, by implication, perhaps EFLI when he was thinking that the "except when there is no possibility of confusion" caveat applied generally).

More generally, EFLI seems to like debating "what is the point?" of the regulation, but that doesn't alter what the reg, says

Personally, I have always fairly 'religiously' over-sleeved blue/black conductors where appropriate, but in many cases (particularly light switches) I don't think I could produce a sensible argument as to why this was 'necessary' or useful - but, again, that doesn't alter what the regs say. In terms of 'useful' (to myself, on occasions), I have always adopted the convention of using brown (or red) for the permanent L and an over-sleeved blue (or black) for the S/L - but that has nothing to do with any regulations.

Kind Regards, John

I suppose I will have to concede and agree with what people have deduced the wording means.

Have the regulations always said that?

Or have they omitted "unless there is no possibility of confusion" from 514.3.1?



514.1.3 would seem to be superfluous when 514.3.1 is in place - and also -

Appendix 7 2.1 would appear to negate it.

 

[RF Lighting]

In the 1997 edition there is mention of labelling switchgear unless there is no possibility of confusion (514-01-01)
Regulation 514-06-01 says that every core shall be identifiable at its termination and that all phase wires of a single phase circuit shal be red. No mention of any get out clauses (I’ve paraphrased a little here)

514-01-03 does not exist

The 2008 edition appears to be word for word the same as the 2018 edition on this.
