Top right hand side of Pic DP MCB with TWECC coming out at the bottom, looks damaged to me where it bends into the enclosure, or do I need to go to Specsavers?I am installing solar to a house and this is there main incoming. I can’t see an Earth anywhere but test ZS across L-N coming out at 0.20. Then with gas bond disconnected is 0.38! But we only have gas bonding. No other earth anywhere. Anyone had this?

You say Zs across L-N...
What about the true Ze or Zdb?
Could be someone had converted it to TNCS without DNO.
What about a pic of the main earth terminal in the cu? And a wider shot showing all the incoming gear.

Wassat blue jobby mid righhand of piccy?Sorry zdb is what I ment. Here is a full pic and there is no main earth terminal. The 6’m gas bond goes from db to the gas meter. There are a couple of dbs that there earths go back to this ‘main’ db. But this main db only has gas bond earth in it. Nothing else

looks like some cowboy has taken a T/E feed from that D/P switch and split the cores.Top right hand side of Pic DP MCB with TWECC coming out at the bottom, looks damaged to me where it bends into the enclosure, or do I need to go to Specsavers?
Yes that’s right which was done by meter fitter. This could be a multitude of problems. But atm I neee to find an earthIt's a burry pic but I think that's a 100A DP isolator with red/black T&E passing through brown/blue shrouds of some sort.
Yes me also, wasn't surelooks like some cowboy has taken a T/E feed from that D/P switch and split the cores.
That’s my new db I’m installing for solar taken the neutral out to drill hole for main tails.Wassat blue jobby mid righhand of piccy?
Can’t see how tho as there is one 6mm earth in db which is gas bondAn earth rod outside direct to CU earthbar?

It’s a old detached house which is a fair few meters away from neighbour. I am stumped atmCould be a much smaller cable to the rod. Readings you are getting would not make me think rod though.
Supp bonding from cpc to pipework that is shared with next door's pipework that is bonded and connected to their PME ?

Not that I can see no
Sorry that’s correct yesSo with the gas bond removed there is no other earths connected to the CU earth bar apart from the final circuit earths?
There is no other earthsSurely you can see the whole of the earth bar? Is there another earth or not? Your answer seems unsure so just need to clarify.
