Please expand on this.......

Ze readings gave me infinity, Zs was good, all bonding in place. So flat was earthed through metal gas pipe. If you look at first photo there is metal conduit which takes tails to the flat but it was not connected to the enclosure therefore no earth to the flat. They did put earth clamp on this conduit and run 16mm earth to the MET inside property but forgot to do it on the other end. All flats are like this...
I did put link to get my Ze...

Silly question But:

That earth connection to the mains incoming, is that clamp just put over the paint, or has it been cleared for a good connection?

From the photo it looks like its just on top of paint.
 
:eek:Check the MOCOPA guide to see what it thinks about BS951 clamps attached to the incoming cable. As a matter of interest what was your Ze after you interfered err sorry interacted with the DNO equipment?;)
 
I have seen several of these but all are after the DNO/Meter. Used as fused isolators for control panels and such like.

On a separate note I contacted the DNO to get my cut out head upgraded from a 60 amp fuse with at best a 6mm (but more like 4mm) sweated on earth to a nice new 100amp with 10mm earth to MET. All because I was going to get two electric showers and an induction hob fitted, honest!

They did let slip that they had to up grade all 60A supplies is a reasonable request was made.
 
@kropaske they must change it by 2010 it says it in that guide I think. And for free. I am just amazed the DNO attended and left it like that, seriously negligent I would be having a head fit with them. In the nicest possible way!

I need to read this guide properly and get as many codes as possible and let customer to deal with them - all in writing rather then over the phone.
When i phoned 1st time about Ze and no earth they said "its not our problem" - i am kind of lost a bit as about a year ago i had same issue with Ze on another job. I' ve ask customer to rang them and they were there couple of hours later digging the concrete and repair cable.

When i phoned them 2nd time about cut out the guy said we will send someone to do "safety check".
When the dno guy came i've ask him to give me some report - he said "we dont do reports", so i have ask him is it safe - he said "i am not saying anything" - this is some kind of joke.
 
Is the neutral bar isolated from the enclosure.
Looks like it is, the neutral bar seems to be bolted through ebonite insulating bushes to those metal brackets.

The BS951 clamp on the incomer appears to have been fitted to the brass sweating thimble above the wiped joint. If this is the case, then it poses no danger to the cable and is probably the best way to make a remedial connection to the incomer. Obviously one should never put that type of clamp on the lead sheath itself because it can easily crush and short the cable.

Nice that it has METESCo (METropolitan Electric Supply Co) cast into the door. Save it if you can!
