Do I need to rewire my ring final?
Former Community Member
Good afternoon, I'm looking for some advice as to whether I need to get someone in to have my ring final rewired. I have recently had a new consumer unit installed and circuits tested. All circuits tested fine according to regulations, but the ring final registered lower insulation resistance readings. live/live 119mohm and live/earth 105mohm tested at 500v. Max Z's 0.52ohm according to the certificate. I'm not sure how old the wiring is but we've been here 20 years and the wire has grey pvc outer sheath, red live pvc, black neutral pvc and 3 stranded earth, which looks like plated copper. Some of the sockets are probably the same age. Strangely, some other circuits with same type of cable registered 999mohm when tested. FYI we live in a 1960's bungalow. Just wondered if you had any thoughts. Many thanks in advance. Simon
Sorry I thought that your first post on the subject was a cryptic request for information rather than a test for me, how did I do?

Yes different requirements for owner occupied and rented. I thoight you may have seen my flow chart for changing consumer units on installations without a CPC? I can send you a copy by email if you want a copy? Or alternatively you could ask the BOD as he may be able to help you!
