no earth

[sima24]

Hi, been to look at a rewire today and no earth connection at all. Tried to contact supply company to enquire weather the property is connected to a pme system but no joy after holding most the afternoon. I presume supply company doesnt have to supply an earth but just wondering if they would upgrade to pme or not? Or possibly it is a pme system but earth has been disconnected at some point (no sign of pme label tho) any views appreciated. Thanks.

And when the existing rod is in a rubble-free position they still want me to move it a metre down the garden to avoid non-existent rubble. Now who's blindly following the regs?

I'm the very last person here, to ''blindly follow'' any code or regulation!! lol!!

You talk some real crap sometimes, you haven't a clue whats below your rod position set just 30cm from the house wall. When i talk about rubble, i'm not just talking about the solid crap that gets thrown out, but all the other old building materials that just get tipped out of the building during construction, most of which won't be doing the soil any favours in the conductivity stakes. As i stated earlier, in the type of soil you have driven a 2.4m coupled rod into, i'd be looking or expecting to see initially, around 15 ohms or thereabouts in an ideal position. But hey, what the hell do i know, compared to your wealth of knowledge and experience!!

eng...let him bat on mate...
he just dont get it....

Please dont connect an earth to the neutral to test for Ze, whats the point you may aswell test between live & neutral its the same thing.If its a TNS do a loop test between the cable sheath & live, for TNCS do a loop test between live and the earth terminal provided on the cut out
,no reading no PME connection. Sounds to me its a TT system & poss using the water main as the source of earthing!

Surley on a TNCS the earth terminal provided is the neutral too??

Surley on a TNCS the earth terminal provided is the neutral too??

its the earth link bloc he`s refering to....often exposed on older cutouts....

This is what you are consistently ignoring: I DO know there is no rubble/solid there as there was already a rod there. What can't you understand about that?

no you dont...
the amount of badly planned, poorly sited rods is legion....
just because `there was a rod there already` doesnt necessarilly meen it was installed correctly.what eng is trying to do here is explain how to carry out the job properly...
anyone can just smack a rod into the ground....what you have to remember is once you have left that site.....the work you have carried out here will have to stand up to varying conditions....whilst still being able to do its job...
come on, this is the main earthing arrangements where talking about for christs sake....

Ok, I do understand how to do it properly, and come the summer (if we get one) I will re-test my Ra and see what I've got in 'least favourable conditions'. (Its my house, remember.) As it stands at 44 ohms disconnection times are satisfactory, so the earthing is adequate.

My spring has now wound down.
