What earth supply is this?

[cakey]

Hi new memeber here and not the most experianced so was hoping someone could shed some light on what this earth supply is?

Got a Ze reading of 0.10 and a continuity of 0.6 from the incoming neutral to the met (both with the bonds disconnected)
Both the 16mm black and 6mm g+y earth go straight into the ground behind that black capping with the main income.

What ya think?
Think the supplier would know??

Not seen anything like that...I'd call the DNO,if no joy from them I'd treat it as TNCS.

might be sweated on the incomer sheath, if it,s lead. best way is phone DNO as wirepuller says, unless you can prise back the capping to see what's what, but be careful of disturbing the incomer

I'd say if in doubt enquire never ---/u/me.

Phoned edf, they said phone the supplier, supplier said phone edf, edf said its def the supplier who should know. An hour later the supplier tells me its a tnc-s! Hooray!! Had my niceic assesment the other day and he said that if the earth conducter is black in his experiance it indicates a tncs but said well done for enquiring. I passed! Hooray!!

well done

It looks TNS to me why dont you do a PFC L-N then L-E and if you get the same reading then its TNCS happy to be corrected on this one

Good tip old timer! Both pfc and pscc were roughly the same.

Plenty of good advice there. Glad to here that DNO and Supplier between them can eventually come up with an answer. In my limited experience, the DNO have been great if I have a job for them to do, but as far as questions about the installation are concerned, I may as well phone my mum!
