TN-S high Ze

Call the DNO, wait 45 mins on the phone. DNO will turn up and give you the option of digging up the street or to go PME..
When you choose the PME option (and you will) they will leave and say it needs to be booked in by the meter supplyer as they dont do it themselfs.

make sure gas and water bond is up to size.
Good luck

I liked that. Is there a Linguaphone tape available too. (NickD post #34)

Inform the DNO......suggest they remove old earth clamp and fit a new HEP clamp and whilst there make it a TN-C-S (if available) system @ their cost.

Why would they remove the existing clamp, renew with a Hepworth clamp, and then PME the system??

I think most here would shudder at the amount of RCDs (of all types) that were returned to manufacturer for replacement on my last and previous projects!! I'm expecting very little change on this project either. And, were talking of a top of the range manufacturer here too!! It's certainly opened my eyes on the reliability of RCD devices!! lol!!

Youd never guess!!!lol
