Fault on socket circuit

[Grant McLaren]

I am puzzling over an intermittent fault on a ground floor/kitchen socket circuit. Initially it seemed as soon as the oven switched on the RCD would trip. However, after unplugging the oven, I used a socket tester on other sockets, which would sometimes trip the RCD. It's pretty random, sometimes it will trip as soon as you plug something in, other times not. Zs reading were fine. The ring main has been broken, although the earths are still continuous. From what I saw, the socket circuit has not been done well.

When I left the property yesterday everything was on, but I'm waiting for a call from tenant to say it's tripped again.

Any thoughts on what it could be and why it has suddenly started now?

Regards.

How many circuits are controlled by that RCD. If it trips randomly it could be that the total leakage to earth is more than 30mA, that would explain why it trips when plugging into different sockets etc.
I had exactly the same happening on a few occasions in domestic installations.

^^ I did say this in a roundabout way in post #2

But I suspect the op doesn’t understand the benefits of these meters .......

Sorry but I just don't see either the point nor the humour in them?

My 7 year old daughter could draw them out better.

If the ring is broken then the chances are at least one of the live wires has come out of its terminal and is loose behind an accessory; every time this touches against anything which is earthed (including a metal backbox) the rcd will trip.
Changing the protective device won't stop this.

... Or have I missed an 'inside joke'?

I brought this up last week about idiotic random pics that keep being put up, tedious, irritating and boring.

I believe they're a reference to 'The Big Les Show' although I think the last one may be the Simpsons.

I don't get it nor see the point of it?? I agree with @westward10 in post #113, it's tedious, irritating and boring. It also has no relevance to any thread you post it on.

I feel the same way about most of Pete's posts - I don't need a dedicated post to tell me he agrees with someone when there's a special button for precisely that purpose, or that he has "nil experience" in the matter in hand but going to have a guess anyway.
Do your worst, I've got a galvanised bin lid.
You got any of that popcorn left Strima?
