Who's right? Hopefully me!

Yesterday whilst doing my practical assessment (2365 level 2) I caused a bit of a stink.
I was working on a couple of 2 way switches with singles through pvc conduit.
As the training centre boss walked past he started over me having blue cable at the switches.
He kept saying 'why have you got neutrals?'
My response was ' I haven't. I'm going to sleeve them brown. Surly it's not neutral if it's not doing what a neutral should do it's just a cable until terminated.'
My tutor had no problem with this method.
Maybe I should have just smiled and pleased him.
Was I right?

They come on this forum?

the only reason we use blue with a brown sleeve is when using T/E where there's no option. in ROI, they use twin brown for switch cables.

In all of Ireland twin brown is used, although in the south it is prohibited to oversleeve.

Never seen twin brown here in the South of England. However used to see twin Red quite a bit.
Serves a purpose, but it's a pain in the bum when you accidentally wire a complete lighting circuit in the stuff.

It would matter if you had a 2 or 3 gang switch and needed to loop the L to the other switches.

Just connect one of the browns to the cpc and bell it out. It really doesn't present a problem. Worth remembering that bs7671 expresses a preference for conductors to be identifiable throughout their length and not just at the terminations.

If someone did it with a single I would expect them to rewire it properly.

@Risteard doesn't the Republic of Ireland have it now that in T&E the CPC is both sleeved throughout and of the same size as the Live Conductors?

I believe that is the case for continental Europe.

SO we are lagging behind again are we?

An incorrectly pulled blue single sleeved and used as a line is very shoddy in my book and I would not permit it on new work at all. Forgive my unfamiliarity with T+E (I only work on projects that are in steel con, SWA and pyro) isn't twin brown usually made with one core insulated with solid brown, and the other brown-skinned white insulation, so you can tell the difference during installation? I've certainly seen red done that way.

Continental Europe does generally use an equal gauge insulated CPC but it's normally in a round cable rather than flat. Aus & NZ also have their CPC like that but the cable is flat like ours. USA T+E has bare CPC.

I have some twin brown and there is nothing to distinguish the core by insulation variant.

I have half a roll of Portuguese flat cable in my garage.
Not seen twin brown, but the twin red I’ve seen had nothing to distinguish the cores.

Sometimes the browns are slightly different shades...good luck with that in good light let alone poor light. Have seen them as Lucien says also.

Last time I used Twin Brown it was an incorrect delivery from wholesalers and I wired a lighting circuit with it

That's correct. The implementation date was the 5th September gone. It's roughly 30% dearer than BS T&E for IS T&E.

Would save on green and yellow sleeving, And no more multi cpcs crammed into 1 length of sleeving

My old boss did that once. Sorry to say I laughed.
