Nic Eic Assessment When Dno Haven't Been To Replace Earthing

[Nuvo]

Hi All what a day ive had.
ive just rewired a 2 bed house with TN-S arrangment. ive come to the testing and the ZE is reading 2.93 ohms. i installed new 16mm to the clamp that was originally on the incoming i cleaned up with the wire brush and tightened. still wouldnt bring it down. so ive called the DNO Western power theyve been out tonite and told me its not one of there earths they have not supplied an earth. they said they can strip back to lead core and provide me an earth for around 50-60 quid but wont be done till the middle of next week. Here is the big problem. i have my first NIC EIC assesment next tuesday so job wont be complete. would the nic eic refuse to see that job as i have no other to take them too. or could i possibly still take them there because i can show i can still test and show im going the right way about things and would be ok. the last thing i want to happen is for them to say its no good re arrange and charge me the 290 quid for rebooking. i was chatting to the western power fella he said to install a earth rod to a tt system but not keen on this idea what are your thoughts sorry if this is hard to understand but any advice will be greatly appreciated.

I seem to recall that temporarily rodding it (albeit with a higher Ze) although on the surface that seems counter intuitive, was to provide a stable "known" if higher Ze, the reasoning behind this was that the TNS earth has already deteriorated and could totally fail at any given point in time leaving the install with no earthing whatsoever, in this sense the TT was the better option until the DNO come out and sort it.

Not a bad thought really that. Daz
