Brown sleeves on switched live cable (lighting)

[JohnW2]

No, it wouldn't. 3 core and earth brown+brown+brown would be very easy to determine which core is which. ... The flat cable's structure would be brown, brown, earth, brown - so you would always be able to tell the wires apart.

Good point - I hadn't thought of that! I wonder if anyone actually makes it (probably not that much smaller a market than brown+brown, I would have thought)?

Kind Regards, John

I feel this has got a bit out of hand.

Marking the conductors of the same colour is no more than 'making notes' for future reference - i.e after tea.
There could be quite a few in a multi-gang, multi-two-way circuit light switch box.

The grey sheaths may also be identified if there are several cables.

That's probably true, but I thought you said that, nevertheless, you do it ....

Ah, that's interesting. I do the opposite, i.e. to identify the permanent live - my logic being it is 'liver' than the other.

The grey sheaths may also be identified if there are several cables.

Sure, but I imagine that most of us do that (with a marker pen or whatever), don't we?

Then you could have brown+brown+blue 3 core and earth cables for timed extractor fans...

One could, indeed - but I suspect that market probably would be too small for it to be cost-effective.

Isn't that the point?
Bas said it shouldn't be done.

It doesn't matter as long as I know.

The grey sheaths may also be identified if there are several cables.

It doesn't matter how it's done.

If I leave a diagram nicely printed with all the permanent lives identified and connected to L2 and the brown strapper I think it would be unacceptable if some of them (no one else would know which) were connected to L3 and the grey strapper.

Apologies - I thought you were responding to my comments (suggesting that they were 'getting out of hand'), not BAS's, and didn't realise that you were actually agreeing with me. Apologies - blame Friday night

Kind Regards, John

RenoMan seems to be a bit of a magnet for barmy electricians.

I haven't met him.

Twin brown I have seen has one core brown right through, the other a greyish white, with a brown top coat.

I'll second that.

Cable markers and a wiring diagram left with the client can remove all doubts

3M do a range of aphanumerics

Using slide on letters (as well as approriate sleeve) all conductors can be clearly identified as SL L N and two way L1 L2 CM etc etc This is extra work during the first fix but it makes the connecting up a lot less hassle and fault finding is much easier.
