Is this an issue.
Providing the cables check out fine then no, it shouldn't be.
Sounds like your biggest issue is potentially the earthing.

I suspect the 7/.029 is actually 4.0mm as I am pretty sure although not certain it was never produced under imperial sizes.I have seen a few lengths of copper clad aluminium, I have some 7/.029 here somewhere. I have only once seen a house wired with solid aluminium cables, horrible stuff just breaks off when disturbed.
I have not a clue what that means imperial is complete gibberish to meI suspect the 7/.029 is actually 4.0mm as I am pretty sure although not certain it was never produced under imperial sizes.
Definitely I’d be tempted to do it on no trip to limit the currentDo I need to be careful is I was to do live ZS test as the earth is all over the place

The bonding isn’t exactly satisfactory And when doing ELI certain meters can pump up to 26A down the earth that would hurt like hell and might have some bad consequences... I’d be wanting to do a full range of dead tests first before doing a ZsWhy do you say that?

I did at first say 26 amps but i edited it and I don’t know why I changed it to be honest0.26A? A normal Zs test should be more than that!
This is why we carry out dead tests before live tests and the regulations specify this order.
Anti-trip tests regularly give incorrect readings and are not a good replacement for a standard efli test,
I did hint at doing the dead tests first several times throughout the thread as wellI’d disconnect the bonding and the bare earths from the board and do an R2 on the bare earth from the end at the board to ensure its complete and then again at the bit your going to connect into and to the board itself and then the pipes themselves just to rule out that the bare earth was coming from elsewhere I reckon if you do that you’ve pretty much proved beyond reasonable doubt that the earth is suitable and actually coming from the CU and not the pipes or anywhere else.
If I do an ZS through calculation, then I will not really need to do a live test do I ?I did hint at doing the dead tests first several times throughout the thread as well
Technically yes but I still prefer to do a Zs testIf I do an ZS through calculation, then I will not really need to do a live test do I ?
