    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.

    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?

    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

    It'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.

    Could 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 ?
