Upgrading tails between DP isolator and CU. Want to use 25mm tails to match the rest of the setup (existing tails are 16mm). What is the correct method for stripping the cable? Should some of the brown/blue inner insulation be made visible atthe CU end, isolator end or both ends? Thanks in advance, Steve.

Not sure if there's a reg about this...
I always strip back enough of the grey sheath (with a stanley) so that the blue / brown inner sheath can clearly be indentified without the need to use a tool at the DNO / head end.
At the CU I strip back 2-3" of the grey sheath, this does 2 things- It allows instant visual ID of tail and helps with the MBR / min bending radi should the tails need to bend at 180 deg (such as tail route feed under the CU, rather than down to the CU.

Am I wrong and if so could some quote why?
Double sheathed tails, so my logic was always that the outer should be removed to ID cable use and secondary sheath colour.
Have I caused a fail if sites are inspected and the coloured sheath is 1" outside the demarcation between DNO supply and customer side?

The correct term is double sheathed as, I'm sure you know, double insulated refers to equipment not requiring an earth.
Red ties would not be good as an identifier now as the colours have changed.Brown and Blue would be the correct choice

Or them (as long as your eyesights not bad)
I hope all the right people are still watching this one so I'll tag onto this one too.
Just been informed of a fail due to tails having a grey outer sheath. Apparently the outer should be the same colour as the inner, so Blue/Blue and Brown/Brown.
I am looking in the 17th edition as we speak, as well as BS6004 and can find nothing to confirm nor deny, but then I am not an electrician so I may be looking in the wrong places!
Can anyone comment (with references if poss)?
Ta all!

Informed by whom? How did (s)he hear about it?
"Failed" in what way, and by whom - do they know what they are talking about?
If this were this so why would manufacturers go to all of the trouble and expense of making cables that nobody would buy?
Oh Ban, you always come across as so accusatory!
I have been informed by my customer, a wholesaler, that their customer, an electrician, has been asked to change tails by the local board because they are grey/blue and grey/brown.
And in case you hadn't guessed, we are a supplier of these cables, so it was news to me too! All I can find pertaining to it is this
Regulation 514-03-02
Every core of a cable shall be identifiable at its terminations and preferably throughout its length.
Binding and sleeves for identification purposes shall comply with BS 5838 where appropriate.
My fear is exactly that Ban, why would I have all this cable ready to sell if from now on, people want/need/require a different product!
Thanks awfully for your input gents.

That's because this whole thing is such nonsense that it beggars belief.
Well their customer can either roll over and let the local board impose this belief-beggaring nonsense or he can tell then to ****-off and die.
And sheathed cables comply with that.
They don't.
If they did, what colour sheath would twin & earth need to be?
My mum always said "If you don't have anything nice to say, ****** !" I can appreciate your label of nonsense, but this really did happen and thus there is truth here too.
Well yes, they can, but not everyone is in a position to argue, or knowledgable enough to be sure, or confident enough to tell the guy that says yay or nay that he is wrong.
Well yes they do, and as it states "preferably" I am happy, but the DNO wasn't so I should tell my customer "Bollards mate, now sling your hook!" I was looking for similar experiences to relate to, or identify this as a one off from a stupid DNO bloke!
Well again, thanks for your opinion, but this guy does, according to the DNO and has now had to source it elsewhere to get connected.
I can appreciate that twin and earth comes in a variety of outer sheath colours, but the cores are marked thoughout their length appropriately. 6181Y consists of one core effectively, and althought that core is marked appropriately with an inner sheath, some might interpret that the outer sheath only relates to that one core and thus should "preferably" be colour coded accordingly throughout its length.
Anyone else care to comment? I believe this potentially rogue muppet from the DNO is operating in the Surrey area, so perhaps those of that persuasion might comment, or anyone who has used or been asked to use blue/blue or brown/brown tails. I know of other suppliers that stock them and I know they are available, and I think I get the idea that it might not be all that wise to stock them judging by the demand, but it's nice to get feedback.
