Urgent help needed on wiring question

[Mikey]

When using a cable that has brown black and grey and you want to use them as live, neutral and earth, which colours do you normally use for the neutral and earth, am i right in thinking

Brown - Brown

Black - Green yellow sheathing

Grey - Blue Sheathing

Thanks

Hi Mikey, that's what I would go for.

Regards wa

:iagree:

 

[Mikey]

Thanks guys much appreciated

Brown - Brown

Black - Blue Sleeving

Grey - Green and Yellow sleeving:yesnod:

 

[edrobbo8]

There was a publication (I think by NICEIC) which said about trying to get away from using black as a neutral, so as you suggested in your first post. Cable colours - IET Electrical

 

[WayneL]

I don't see what difference it makes if you're sleeving it -

...in fact, surely it would be safer......if the blue sleeve fell off the black conductor, anyone old-school would think it's a neutral anyway......if the green/yellow sleeve fell off the black conductor, no-one's gonna think it's a CPC.

What colours would you use if running 3 core & earth to a fan with a timer, or a maintained emergency light fitting.

 

[truckster]

Brown P/L
Black S/L
Grey N

I always use the grey as a neutral

 

[Electro-tech]

College Tutor told us to use Black for Earth as it was the nearest colour to describe Earth. I suppose you can have grey Soil!!

 

[telectrix]

i prefer the green/yellow soil. for EMs i use black as perm L. brown as SW/L, grey as N. by using these colurs when you have a mix of EM and non-EM's, then brown is SW/L throughout.

Wouldn't brown be the closest colour to earth?
I reckon the neutral wire should be beige, or magnolia.

I like to use the brown as P/L as the terminal is often marked L1, the black as S/L as the terminal is often marked L2.
I prefer to have a mix of browns and blacks for S/L as then it is obvious to anyone taking the switch front off, that there is an item of equipment with a P/L.
In any event, when having to use the black for either the P/L or S/L, it leaves only the grey available for use as a neutral. I wouldn't like to leave an installation with a mixture of black and grey neutrals, with other greys being used as CPCs.

 

[nickblake]

on a single phase cable Technically when the cable is over sleeved or marked (with the exception ofsingle core green and yellow )the over sleeve takes president of the underneath and there fore any combination can be used ,how ever a convention has generally accepted of over sleeving or marking the black green and yellow (CPC) and the gray with blue ( Neutral) the thinking of this has been done with the aime of helping dissasociate the black with the neutral and the shade of gray being a neutral colour , on a 3 core L , L1/SL, N ,CPC the black will become the switch live and be sleeved with brown sleeving

Part of this is an answer from the ECA today

The cores, only require identifying at the terminations, which could be by colour or alphanumeric means.
It's not required to oversleeve them.

 

[BillyTheSparks]

Old Colours L1-RED L2-YELLOW L3-BLUE
New Colours L1-BROWN L2-BLACK L3-GREY

Now I always sleaved the yellow as the earth, as the blue and red was obvious.
So now I sleave the black as earth and the grey as neutral.
If im using a 3core and Earth using another core as a Switch Line, the black is used as SW/L and sleaved Brown.

 

[rallyandy]

says a lot for harmonization when we all still have a different method of identifying conductors lol

what i can't understand is, back in the 90's the IEE made the regs. into a BRITISH Standard so as johhny foreigner could not interfere with our standards. lo and behold along come the brussels bureaucraps and makes us adopt these stupid new colours which nobody agrees with, nobody wants. next thing they'll have us driving on the wrong side of the road and eating frog's legs and cheese.

I'm bored with the EU, I reckon we should call it a day. They seem to exist purely to boss us around and cost us money. [/euro-rant]
Cheese is good though. Best invention ever. Loads better than sliced bread.

 

[telectrix]

but you need the sliced bread to make the toast to put the cheese on. agree with your comment on the eurinal. time we got out before we have the germans in control ( like they tried in 1940 ). why should we be forced to pay out billions to get greece and spain out of the sh** they have made for themselves ( no offence to mayfair ) . wonder if ken has any thoughts on this.

Correct it was called De-neutralizing the black

You could have an old-fashioned tin loaf and slice it yourself.
It's not just the bailouts though, take the harmonised colours for instance - we were told it was to bring everything in line with the rest of europe, so we fell into line and started using the silly colours while the rest of europe continue to use whatever colour tickles their fancy.
You can't open a newspaper without seeing a story about some new euro-nonsense which is being foisted onto us, eroding our national identity for fear of massive financial penalties, while every other country just do as they please.
It seems the main purpose of most of the EU directives seems to be to see how silly they can make the British look. Well I've had enough.

More to the point they make these stupid euro directives/nonsense and we the British like fools follow them while everyone else sticks two fingers up to it and takes no notice.

But without sliced bread....we would have no cheese on toast. Its an essential partnership..that isnt however, a foody metaphor for the EU, they can do one and leave us alone, just leave behind some St.Agur and a nice creamy Brie on their way out

 

[telectrix]

we don't need their soggy cheese. we got cheddar and wensleydale.

It could be though - while pre-sliced bread might be mildly convenient, if it came down to it a bread knife is a lot cheaper than an industrial bread slicing machine, plus if you slice your own bread you have total freedom over how thick you choose to cut the slices; who do these pre-sliced loaves think they are, telling me how thick I should have my sandwiches.

the problem is that most toasters won't accept thick bread. also it's clear that toasters were designed by a woman as they should be horizontal, otherwise the cheese makes a hell of a mess in the toaster, not to mention eggs.

It doesn't stop there - we have Red Leicester, Double Gloucester, Stilton, Dorset Blue Vinney, Cornish Brie, Stinking Bishop, Innkeepers Choice...
British cheese is the best in the world and we don't need EU desk jockeys telling us how to make it.
