Sleeving of 5 core cable for lighting circuit.

[kodr]

Hi,
I have a technical query in regards colour sleeving of conductors in a multicore cable. Take a 5 core 2.5sqmm XLPE SWA cable with all white conductor insulation. I want to use this cable for lighting circuits in an industrial installation, can I sleeve the cores to they’re respective phase colours and the neutral to blue and earth to green/yellow etc ?

Is the acceptable practice in accordance with the IET Wiring Regulations Seventeenth Edition ?

In the BGB look at regulation 514.3

I would also make sure the numbers are still visible in case of loss of sleeving and perhaps note the numbers on the installation certificate.

i would not sleeve conductors as grey or black. all "live" conductors should be sleeved red (sorry, brown FFS)

How would you identify and indicate each phase in that situation? Just the numbering? I thought 3 phase had to be brown, black grey?

yes, it does but when using bn/bk/gy in a single phase situation should be sleeved brown, e.g. 3 core strappers between 2way switches

can I sleeve the cores to they’re respective phase colours

I think this part of the question was overlooked,someone hasn't been eating their carotts

Brown is acceptable to identify all 3 phases even on a 3 phase installation

Thanks all

whatever way, the sleeving will still be muddy, hard to see in poor light , stupid foreign harmonised ( with who?) daft phase colours.

Bring back Red/White and Blue I say

Don;t someone say Yellow,that was when things started getting silly


Just a thought,
I wonder if anyone knows "why" they came up with these silly colour schemes ( because I don't)

Was it because they are so inappropriate that no country had ever thought of using them, it was ideal for not having to chose between any country

Bring back the British Empire, make it Red, White & Blue!

It all went wrong in 1977

Definition of Harmomisation is making something that no-one can understand,, then there won't be any confusion.
