On the EIC the max Zs for the ring circuit looks suspiciously high and leaving the RCBO leads loose in the back of the CU B is sloppy too
So in this situation, what should I do? Based on what people have said, it seems the bonding may not be installed correctly, the bonding earth should not be connected to a socket, there may be some poor workmanship on the new installed fuseboard, and the test results seem suspicious.On the EIC the max Zs for the ring circuit looks suspiciously high and leaving the RCBO leads loose in the back of the CU B is sloppy too
Doubt that would help!Let’s hope the spark that did this is reading this thread

What happens if he refuses?

The protective conductor (earth) for a circuit must be part of that circuit,
From what I saw when he was adding new sockets he extended the ring with new cable but I guess there must be a point where the old cable would go back to the fuseboard.Don’t panic. It sounds like it’s now better than it was before. I don’t think there is anything that is immediately dangerous.
Start asking friends etc. for recommendations for a good electrician, for next time. But only ask friends who you think you recognise good work from bad, else you end up with someone who is just very friendly and tidy.
It sounds like there will be a “next time”, since apparently you still have some circuits wired in rubber cable.
