Discuss 3 core twin and earth cable what colour should you use as the neutral in the Electrical Wiring, Theories and Regulations area at ElectriciansForums.net
Just make sure you use the same colour at each end of the cable.
If the bloke before you can't be bothered to sleeve the cores then he isn't going to worry what colour the neutral is.

IMO it would be better to have the "wrong" core used so long as it is sleeved correctly rather than the "correct" core unsleeved.

Cool.....As said sleave them for my benefit, couldnt work out why I was getting 'odd' readings on testing a faulty bathroom fan..........

Black, Blue and Brown in one, 2 Red and a Brown in another and a Yellow/Green and blue in the last................QUALITY
It would appear that an earth is being used as a live conductor?
In that case, should it be sleeved grey?Seen that done before with SWA as neutral
In that case, should it be sleeved grey?
No it shouldn't be sleeved grey, just me taking the ****.
Not quite Nick. There needs to be a standard so we all know what is going on, that's the idea of having identification in the first place. In a 2 way all are line conductors so there is no ambiguity, whereas in a switched circuit (IE PIR) ther has to be one who is neutral, and thats grey. Using yellow as the CPC and blue as neutral in RYB colours was easy as blue was then recognised as neutral in flexes, and yellow... well that's obvious. When the new colours were introduced the NIC and others were quick to make a standard to enable all to understand the colours, it will make your life easier if you go to a job and there is no sleeving!

If they really did have their way we would be using black as line on 230. We chose the standard we have now to stop the eurocrats choosing. If you don't like or can't cope with the new colours try buying the old ones. Maybe some people are just too adverse to change.
I've been in the industry 30 yrs and am not averse to change....However this country has a long and distinguished tradition of implementing daft ideas....and harmonising cable colours has to be up there with the daftest.

A standard is just that, something drawn out that people stick to. If you don't agree with grey as neutral; tough. It was decided a long time ago that was the case and it has to stick. If you continue to be a rebel and create your own system you are creating problems for everyone who works on your installations after you. Just because you have 3 colours in the neutral bar (colour coded with sleeving of course so not to cause confusion) does not make it difficult, it just makes you dim if you don't understand it.
Haven't read all the posts in this thread but have caught the jist of it. Doesnt table 51 state AC power single or three phase circuit neutral colour BLUE?????

Thanks to this piece of genius thinking we now have a situation where blacks and blues could be either phase or neutral...and drab dingy phase colours which are hard to tell apart in low light..and just to let everyone know how silly wev'e been we have to stick silly stickers over every DB pointing out our sillyness.
The UK is an island...there is no overlapping of wiring systems with our european masters...we didnt need to change.
