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 ?

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

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

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

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

...stupid foreign harmonised ( with who?) daft phase colours.
Nobody was using the harmonised phase colours, however all of Europe minus the UK was using Blue for Neutral for fixed wiring, we had however, been using it in flexible cord for a number years. It was the UK harmonisation working group that proposed Brown, Black, Grey for the phases to CENELEC. They expected to have a fight on their hands and had a bargaining strategy planned, however the proposal was adopted with barely a whimper from the member countries representatives and no bargaining required (the only time, so far), despite every country having to change to the new code.

My mentor when I was training also did TV, video repairs. He said he spent a lot of time getting qualified, only for it to go down the pan after a few years.
Almost like PV eh?

yeah, mine went down the pan 1980. the stuff got more reliable and punters would not spend £30 repairing the old TV when they could get a brand new one for a tenner down and change of address. was good while it lasted , though. esp. over crimbo. instead of a tenner call-out, it was a score and i was doing 15 calls a day.

The TV repairman would tap the valves with a screwdriver, replace a couple, maybe solder in a new component, those were the days. He would need a microscope these days with SMT, but as said TV's are so cheap you just replace them.

good old days. when cpc first started, they sold 2nd hand valves from stripped out scrap TVs. they came individually wrapped in newspaper at a fraction of the cost. look at cpc now.
