on the left we seem to have a DNO supplied TN-S. on the right some bodge earthing of SWA armour.

Hi telectrix,

Ok so it's not a PME and TNS then? That's what my first thought was. I thought the right was a separate Neutral

Would that be one redundant incomer, if so the newer (right side)is a split concentric and TNS - I love the 'cut out caption' questions.

Edit - the CSA are too large for split concentric

Hi Mark .
Looks good
what is it ? TN -S or TNC-S ?
look like there is two cable feeding the service head very odd looking

If your ZE / ZDB reading are as expected, I would FI it and definitely get the electrical company out to look at it, UKPN or the appropriate company for the area your in.
