If we stick to a regime then it helps with an initial identification but even then we all should verify anyway.

I'm not sure that there is ever any need/reason to 'verify' that a conductor connected to a light switch is a 'line' conductor, is there?If we stick to a regime then it helps with an initial identification but even then we all should verify anyway.

I think there is a limit to how far we need to (should) go in taking account what crazy things some people might do!Unless of course some tw at has switched the neutral
Very true, but if they don't understand that no neutral would (shouldAlways put a brown sleeve on, not everyone knows black or blue isnt a neutral
Yes (normally) they could be said said to be Line conductors, but the ID is meant to give us the first indication of which one, mostly Sw Line or Perm Line (or indeed from which Phase it might be fed in some instances, it used to be allowed to use the 3 phase colours in large single Phase installations too) . Secondly N as well as Line conductors are indeed allowed in the back box of single pole switch boxes along with the E conductors and of course DP switching of lighting or anything else.I'm not sure that there is ever any need/reason to 'verify' that a conductor connected to a light switch is a 'line' conductor, is there?
That is not true.but the ID is meant to give us the first indication of which one, mostly Sw Line or Perm Line

... but there is no requirement to identify such functional things - the requirement merely whether a conductor is (or sometimes may be) connected to 'line'. I have personal 'conventions' which help me to distinguish switched line from permanent line, but no-one but me would understand themYes (normally) they could be said said to be Line conductors, but the ID is meant to give us the first indication of which one, mostly Sw Line or Perm Line (or indeed from which Phase it might be fed in some instances ...
Indeed they are - but, as I've said, you will never find a N conductor attached to a 'switch terminal' of a switch.Secondly N as well as Line conductors are indeed allowed in the back box of single pole switch boxes ...
As above, something such as my 'personal convention' can be useful in relation to 'functional identification', but most people don't do that (and others won't recognise their convention, anyway). However, I'm not sure that any thinking person would feel that it was necessarily "a good idea" to identify a conductor which could be only "L" by virtue of what it was connected to.Who would not think ID indication (by colour or alphanumeric label) is not a good idea?
- but, as I've said, you will never find a N conductor attached to a 'switch terminal' of a switch.
and triple pole extractor fan isolators.... and of course DP switching of lighting or anything else.
Fair enough - you've both got me there. Yes, with DP or 3-pole switching, an N will be connected to a switch terminal - so my comment shlould have been restricted to SP switches.and triple pole extractor fan isolators.
but, as I've said, you will never find a N conductor attached to a 'switch terminal' of a switch.
OK - so you were just commenting (legitimately) on my statement, but still agree that the conductors going to a (SP) light switch do not need any 'identification)?My point was nothing to do with identification. ... You said:
Of course; how could there be any doubt?OK - so you were just commenting (legitimately) on my statement,
I do - but having 'SP' in brackets in such a sentence is rather strange.but still agree that the conductors going to a (SP) light switch do not need any 'identification)?
