oh ,forgot the kettle ,teapot and cup.lol.That's it, just T
Is this something you know the answer to Zerax or something you are unsure of?View attachment 62306What sort of earthing system would you say this is ?
Hence TWTFTE...... where the f*cks the earth
The earth conductor just goes from the cut-out to the CU.TN-C-S.
The earth conductor disappears behind the bottom of the cutout, then reappears above it. You can just about make out the green/yellow between the live conductors.
I think you are assuming too much competence on behalf of the meter fitter!If there was a problem with the Earth then that new smart meter should not been
Put in.
No... they're separate. No connection between them at all.Is the link between the neutral and earth terminal in the cut out still in place ?
Agreed. The seals on the cut-out and meter covers were identical and looked correct to me... so I'm guessing it was the same person.If there was a problem with the Earth then that new smart meter should not been
Put in.
Is it ohl, or is the a proper head somewhere?No... they're separate. No connection between them at all.
Must admit, I was wondering if it was fitted, or had ever been fitted.Is the link between the neutral and earth terminal in the cut out still in place ?
ProbablyI think you are assuming too much competence on behalf of the meter fitter!
TN-C-S is like that. Just two cores in which may be separate cables overhead, or concentric (buried or overhead). Inside the service head (a.k.a. main fuse unit) the earth terminal is linked to the neutral conductor. Out in the street, there will be multiple points where the neutral is earthed - hence the name "PME" (protective multiple earthing).I thought it was quite obvious that the earth was unconnected, as it isn't a main cable entering the head, just two cores, line and neutral - is it fed from overhead lines, or is there a proper intake head somewhere?
So what did they do, just link the earth terminal to neutral in the cut out?After a few words of bemusement they 'converted' it to PME for me.
But that isn't configured as as a main intake head aka service head, there would naturally be no connection between the neutral and earth connection.Must admit, I was wondering if it was fitted, or had ever been fitted.
Probably
As I recall, when I had an isolator fitted, the guy didn't take any measurements at all - only a quick check of polarity.

As long as the neutral conductor doesn't get broken, this does give a very good earth.
Exactly !So what did they do, just link the earth terminal to neutral in the cut out?
That is the proper head... it's a very normal terraced house with nothing else weird or whacky.Is it ohl, or is the a proper head somewhere?
