3 core twin and earth cable what colour should you use as the neutral

3 core twin and earth cable what colour should you use as the neutral. Or can u use any. As long as u label it with blue sleve

 

[malcolmsanford]

Had to think .................isn't it grey so as not to confuse the black with the old neutral colour ......

 

[Sintra]

I think it is a NICEIC recommendation that the grey is used and sleeved obviously, although it shouldn't matter so long as all cores are correctly sleeved.

 

[mogga]

the ESC suggest using the grey so not to confuse new and old colours but so long as they are sleeved correctly any could be used Grey is just prefered

The thinking is to remove the association of black with neutral...as black is now a phase colour.....this ignores the fact that 90% of the UK neutrals are ,and will be for a long time to come....er....black.....makes perfect sense dont it?

Just make sure you use the same colour at each end of the cable.

like when using 3 core armoured for single phase, sleeve the black with green yellow and grey with blue.

Think of the new reccommended harmonise connections. Red to Brown Yellow to Black & Blue to Grey. We always used yellow for earth [ if using 3 core SWA for single phase ] so now use Black [ with G/Y sleeve]. Blue was Neutral so Grey is Neutral [with Blue sleeve]. However I've seen [ & others proberly have] Black for Neutral & Grey for Earth. As stated as long as it is identified both ends there is no problem, regards piccollo

use whatever you want. they'll probably change all the colours again when the suits want to justify their huge salaries for sitting on their ***** telling us all what we can and can't do

This is where i've been going wrong!

 

[nick611]

ever notice that when we used blue in the old triple we didnt sleeve it black, after all blue was a phase colour back then. myself i use the black with blue sleeve, it just makes sence dos,nt it

 

[keefy]

GREY, it has to be consistent. I shoot people for using the black as neutral, just for fun mind!

 

[ste mac]

I use the grey as neutral as it is the opposite side of the cpc to the brown as in 2c twin & earth

 

[nick611]

so when you use a triple at a 2 gang sw, brown across the top and grey and black as sw lines your neutral and earths [black + grey] are both live cables. like i said its up to you as long as its sleeved. no one told us to use yellow and blue like we did we just did it. so now we can use black and grey as we like

 

[telectrix]

as i said, this time next year it will be pink, purple and orange, with red as earth

 

[keefy]

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 the bloke before you can't be bothered to sleeve the cores then he isn't going to worry what colour the neutral is.

If he has paid attention to what colour should be neutral he will. Just because he is lazy does not make it less likely he will use the wrong core.
