RCD will not stay on

[PrenticeBoyofDerry]

I was waiting for that comment!!

No... just took me 3 months to upload the pics from my phone so I could post them. The smell was horrendous though!

Don't talk to me about phone pictures, just lost about 500 of them!

They can be very smelly (dead rats that is)!

Here is the reason why the RCD kept tripping!

Glad you discovered the cause I suppose I almost got it right, apart from the gory details ....

That obviously makes it less likely [typo corrected] that anything within' the cooker is at fault - suggesting that the most likely place for the problem is where the supply enters the cooker or somewhere else in the wiring of the cooker circuit.

Kind Regards, John

Brilliant! You guys are awesome. Thanks for the great advice John. I'm so glad this is in past and I can laugh about it. I was not laughing when I was force-pulling that sucker (but spelled with an "f") out by the tail.

You're welcome! I've suffered too, but I think the culprit was (somehow) more lucky than yours, and I certainly didn't come face-to-face with him ....

Here's one of my worst finds

Also found another cable in similar condition near by complete with maggot infested rabbit still attached

Ah - but yours hasn't got three bits of shiny copper lying side by side, like mine

Kind Regards, John

It has in places. The middle inch or so of the very bottom blue is stripped bare. It's just the copper has tarnished as it must have been like that a little while.

Fair enough! There were, of course, other areas of gnawing along the length of my cable, but I photographed just that one bit because of the three bare conductors side-by-side - mainly as a means of illustrating that one should not feel too reassured by normal IR measurements (which, needless to say, that cable had)!

My cable was chewed all over the place, and also passed an IR test with flying colours

We ended up rewiring in a combination of pyro or steel tube.

Steel tube should ought to foil them, but I wouldn't have thought that pyro would necessarily be an adequate match for their teeth, would it?

We used bare copper pyro, which I'm sure they could easily chomp through if they wanted but the lack of plastic seems to prevent them taking an interest.

Also pyro always fails safe if it's damaged which is a real plus as this was a timber building which spends much of it's life unoccupied.

I'm not so sure about that one. It can be a risk if not RCD protected clipped to wood. If the sheath gets pierced the IR will start to drop and at some point it has the potential to work as a heating element, cooking the wood its fixed too

It really doesn't take much to pass insulation tests. Dry air is a very good insulator, most plastics are even better.
