What should i do with this one?

[egginyourface]

The other week i got a call from a little granny who had a leak in the loft which caused some of the lights to trip out and sockets etc.

I went there and isolated the affected circuits. I said i would go back in a week after everythings dried out and recconnect.

Any way, i though i would do a little zs on some of the sockets. Results i was getting was 2.19 ohms.

So i did a Ze test at origin and found just over 2 ohms. Checked main incomer and found there was no earth coming from the head.

We called eon and when they came round to have a look they told us that it wasnt there problem and it was up to the electrician to supply earth via earth rod.

The property is not in a rural area its on a normal street.

The board is 16th edition board, so was thinkng i would put a couple of rcbos in for lighting and sockets and stick an earth rod in.

Is this ok, would i need to put an rcd before the fuse board??

2 ohms too low for a TT?
The best I've ever had was 0.29. Mind you I didn't just mess about with one twig sized rod, I went very very deep.

well what i should have said here is that it isn`t too common for a TT to be that low.....but i didn`t did i ..lol.....

Had a similar situation a couple of years ago. Contacted DNO and they were there within the hour. TN-C-S provided. Presumably there is evidence of an existing earth connection at origin ? If so and not TT, I would contact them again being more insistent.

so which DNO was that then?......i know there like slugs round here....thats if they can be bothered to get of their arses at all.....

We should have a sticky thread about DNO experiences. I'd bet there are some howlers, I had one a while back where on a TN-C-S I had no Ze, rang up to tell them about it and some woman said "Oh no that's nothing to do with us, you'll have to call an electrician"

About 30m down the East Lancs near John Lennon airport (believe it or not)

I too had this problem .... DNO said they would provide an earth, but only if customer paid them £150 + VAT, otherwise I would have to TT it.

(we got around it though )

yep...all sounds familiar does this one....leigh n I had the same sort of verbal diarrhea from some stupid bint on the end of the phone just the other week.....and she didn`t stop there either....went on to intimidate the customer n all.....thing is though ..DNOs have a responsibility to maintain a reliable, stable earth for THEIR apperatus.....the fact that they will allow it to be used for a means of earthing a consumers installation could be taken as goodwill....or something like that.....but the way they behave when they just dont want to see to something is abominable.....like this scenareo we had where i pointed out to the DNO opprative that the blanks were missing on the cutout and the fact that the CUTOUT (DNO property) had no means of earthing......."not our responsibility"!! he snapped....oh yes it is pal....i thought......bloody pain they are......leigh`s had loads of nonsense with em....

I didn't say it (for fear of being laughed at for being a mere trainee DI if I'm honest) but I thought it was the DNO responsibility to provide the earth for their kit (ie: before the fuse)

It's their responsibility to maintain an earth facility if they have provided one mate
