Quick question

[JohnW2]

I do - but having 'SP' in brackets in such a sentence is rather strange.

Maybe 'rather strange', but I would think primarily because it's usually taken to be implicitly present.

Although it wasn't admittedly stated, I assumed (maybe wrongly?) that we have been talking about 'light switches'. That certainly excludes 'fan isolators' and would very rarely involve DP switches (other than, perhaps, in the case of outside lights).

FGS John, you wrote:

but, as I've said, you will never find a N conductor attached to a 'switch terminal' of a switch.

which is incorrect - get over it.

Also in a loop terminal

I've fully admitted that I was only thinking about SP switches when I wrote that. I really don't understand why you feel a need to keep going on about it.

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?

I find it helps to distinguish Perm L from SW L, initially, my preference used to be with say Red and Black T & E for example, the proper Red was Perm L and the Black sleeved as Red was the SW L. Accordingly I followed the same convention one Brown and Blue was mandated. Three core and E similarly , the true Red ( Brown) was Perm L and the other two were sleeved Red or Brown appropriately. I do realise that a lot of folks do not follow my thinking but to me it seems logical.

I have always tried to follow red/brown as perm L if there is a choice

I agree - and, as I've said, I have always had my own personal 'conventions'. However, since they are 'personal', they would not have meaning for, or even be apparent to, anyone but me!

If you was to use twin brown would you bell them out and sleeve one brown with brown sleeving....maybe?

To be serious, that's one downside of twin-brown (which I've never used). With other cables one can at least know 'which conductor is which' at both ends, without having to do any 'belling out', and can then, if one so wishes, 'identify' the conductors however one feels is appropriate/necessary.

I used to use twin brown years ago, don't see it much now....if I remember correctly one of the browns was completely brown and one had a white inner (if you looked at the end) I think.

I've never installed any myself but I'm sure some I've dealt with have been distinctly different browns.

I would not use twin Brown ( I never used twin Red, it cost about £2 a roll more back in the old days so virtually nobody bought it so it kept costing more, ad infinitum) . Remember I am one of the dave a shilling brigade. It actually makes it easier to add a sleeve to the imposter there helps make things clearer LOL.

I did know an Electrician who bought a roll along with a standard roll and then mixed his rolls up , hah ha didn’t half cause some problems with his loop in of a whole house!

 

[ebee]

PS black sleeving was available but rare and no he didn’t use it, bits of black tapes he belled each piece out when he discovered after all the first fix including plastering over was done , a lot of his tape dropped off, the finished result was a bit confusing to the unwary .

Anyone started fixing T & E then found that the cable had not been thru the chalk bath? Actually it had probably been thru but the bath had no chalk in it. I only got that once but I know other who got a few! Hard work if you done more than a few runs!
