CU change and sub main upgrade

ok then if its still high...then as others have already suggested... contact DNO...make a note of it (time date etc)...get them to make a note of it n all over the phone.....this way you`v covered your arse....

oh, and if they start the `youl have to pay for it or its a TT` card...then tell em that as the install is using their supply as the earthing at the time of this.......then they have a duty to maintain it ash......dont put up wuth any bull they may try to throw at you....if they start this lark....hold your ground.....its their aperatus....their duty to maintain it.....simple as...

Whilst your Ze is higher than the norm, the requirement is that Zs measures low enough for the circuit protective device to disconnect within the maximum disconnection time as specified in the regs. If it passes, it passes - regardless of Ze.

well this is all very well....but i would not like to think that possibly extranious conductive parts were the only thing preventing high Zs....

Ze testing is to prove you have a reliable earthing external to the install....as the O/P has posted...its high....OK so only by 0.04 ohm....but nether the less...its still high...

Sounds like a reliable earth to me. I wouldn't think the DNO will entertain digging up the road over a matter of 40 milli-ohms, but as mentioned in a previous post, it certainly would be interesting to know how they respond.

Hi all, thanks for all your input. Will be ringing the DNO tomorrow and will let you know the outcome. Cheers.

Update: Called DNO (UKPN) and they put me through to a very nice young lady (young to me anyway !) she asked where I was getting my readings from and said that it was out of spec and logged it as a fault and an engineer will be on-site within 24hrs and will call me when he's on his way.... and no Glenn I'm not joking.... she also gave me a ref number and a freephone number if I needed to call her back !... that was at 9:45 this morning. Lets see when they get here...

Good to hear Ash. Keep us updated.
