I read that...I wonder if there is official info about replacing those cut outs.
I think i need to ask customer to approach them directly and get everything in writing. There is too much danger stuff going on there.
I guess it would be different story if this would have been a house - only 1 cut out to be change. Here is 6 in total so obviously shareholders would not be happy...

Just had a flick through that, that's a great guide. Are those codes a DNO standard or would they not know what I'm talking about if I mentioned one on the phone

official info

Check the MOCOPA guide I posted. @Jamchiv01 never mind the codes its the condition referred to when you speak to them, that is the point, if they think its bad just describe the item, they will catch on.

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.

Just to acknowledge the source of the MOCOPA guide: @snowhead

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?

All paint scraped nicely...

Okay, Nice neat job

Brave person to put a clamp on that or any supply cable.

So looking briefly at this guide and assuming westward is right about neutral bolted to the box there is already code A07 page 27 exposed live parts...
