Ideally, you should disregard the clamp and fix the label under or above the MET with screws.

Alternatively, there are specific plastic labels that can be used.

Hey Chris,
Its just dawned on me you were talking about the connection at the supply end weren't you? That was the existing earth cable I used as I wasn't sure if I was allowed to mess with the supply end of things but I think you are right...it makes the rest of my work look unsightly doesn't it?

Jason is this the label you were referring to chap?

Sorry for the delay answering. I picked up an 8 way just to keep it neat. Here's the finished arrangement....

So, has nobody got any qualms at all with the BS951 clamp on a lead sheath, which is the DNO's equipment?

Please say someone has....

Hey Pevvers.

I take it that's a no-no. But its been there since "whenever". I changed the consumer unit and got the installation up to standard according to BS 7671 and advice from the NICEIC. Would I have to have that changed that as well? The Siemens engineer (for Brit Gas) came down to fit the DP isolator and didnt bat an eyelid when he saw the earth cable.

What would you do chap?

Quite right Pevvers, should either be a Hepworth clamp or a TNC-S system. 951's are very much frowned upon and shouldn't be used on a sheath (lead especially) (unless a supply employee fits them)

I'd ring up the DNO and ask for them to come and install a system that was up to the job of getting an earth from a lead sheathed cable. The problem with the BS951 clamps is that they can become loose against a soft metal like lead, and as they are tightened up over time they can then cause a short between the line and the earth... And I'm pretty darn sure that there will be a pretty big bang when this happens!!

No offence to the DNO operatives, but from what I've heard they don't really give a monkeys about much anyway. I would like to be proven otherwise though!

OK chaps...Advice time...........

I am getting a Ze of 0.11 ohms and functionally everything is A- OK. That BS951 on the lead sheath has been on there for god know's how long. I Realise that clamping a BS 951 on a lead sheath can potentially crush the conductors inside if overtightened but this does not seem to have been the case. What would you do in the same situation as me?

Sorry Pevvers,
We must have been typing at the same time
Cheers mate. I will get on to the DNO and talk the NICEIC tomorrow......and of course let you know how helpful they were(n't)

I'll put a fiver on the NICEIC being helpful, and a fiver on the DNO not being helpful. Let us know if you even manage to get through to anyone at the DNO who has the foggiest what you're even talking about!

No need to apologise!

lol! Cheers chap.

I make you right the NICEIC have been great all the way. The reason I want this job absolutely perfect (apart from the fact that I want all my work to be perfect ) is that the NICEIC will be inspecting it as part of my approval as a Domestic Installer.
Make you right with the DNO though! Although in fairness when I asked British Gas to come down to fit the DP Isolator they were down within a few days no fuss. When I tried to get EON to install one at my mum's house so I could work there too, it took about 6 calls before anyone had the foggiest what I was on about!!

I'll be back with more news on the morrow.

Thanks again to everyone for their input.
