Not like you . Promotion has mellowed you.
He is coming over a bit mellow at the moment. How long before his moustache slips?

I meant Midwest... sorry Westy!
Open to suggestions providing it doesn't contain the word head and other body parts.He needs to change his name. Something more befitting a Moderator.
I agree with Westy, the circuits cannot now be independently isolated, anyone working on the RFC in the future could potentially get a shock from the cooker circuit in the event of a fault on the cooker.
It is as BL says like borrowing a neutral, as soon as that link is disconnected there could be a potential difference between the two earth conductors.
Big problem with temporary repairs is that they have a nasty habit of become permanent repairs!
Also, what has now been done must surely screw the test results for the RFC, so how do you document that in the EICR?
Correct thing to do would be to isolate the cooker circuit and label it saying it is not to be used until remedial action has been carried out and document that to the client.
So you would have just left an unearthed cooker and microwave (also on the circuit) unearthed would you? Or say to the tenants you can't cook for 2 weeks? I have left it in a safer condition than it was. It is now effectively earthed.I'd just isolated the circuit, with clients permission of course.
You've not really done a permanent repair, and now your liable, should anything go wrong. If it was young family or someone frail, then as a temporary fix ok.
Better go bang than electrocuted..bang.
Not sure I understand where you're coming from.. I've done all the applicable tests, no other faults found.Hi - to me that circuit is proven to have a fault and the cause of the fault has not been found. There may be other faults or sections of the cable without CPC. CPC for 6mm is typically 2.5mm and the circuit has been returned to service with 1.5mm CPC from another circuit if I've understood correctly (?). I'm afraid this does not pass my sniff test for a fault free circuit, but I'm happy to learn .
I you Have done a Eicr ,then it would be unsatisfactory in my humble option,I've done all the applicable tests, no other faults found.
32 A cooker circuit same as 32A ring circuit. There are TWO 1.5mm earth wires in a ring circuit in these parts,

32 A cooker circuit same as 32A ring circuit. There are TWO 1.5mm earth wires in a ring circuit in these parts, although I grant you in the unlikely event both circuits have a simultaneous earth fault that may stretch things a little but are you saying it wouldn't trip?
As stated, I put warning labels on the fusebox and at the socket concerned which is right next to cooker switch. Also noted in the eicr..Ok I give up, I'm orrffh to cook a curry is my excuse.
My thoughts were that the cpc must remain effective throughout the life of the install. Therefore, if the RFC is altered or removed subsequently, the installer altering/removing may not know the other circuit is reliant on its cpc.
Yes cooker wires 6mm and 2.5mm. the link I put in was 2.5mm also..Trouble is the diffence in size of cpc. 1.5mm on a 2.5mm ring (essentially 3mm) the cooker if in a 10mm t&e.. With a 4mm cpc... 6mm t&e is fine at 2.5mm cpc
Yes..If you got those readings of the same lighting circuit, then I would say there is a fault on that circuit. Did you disconnect the earth and neutral for that circuit out of the board before testing?
Sorry, line and neutrals disconnected, not earths..Yes..
Hi - I agree you've left it in a better state than when you arrived, no question. It should trip if there is an appliance fault. But as it's not been possible so far to find why there is a 2K Ohm CPC then we can't say what has happened to that cable with certainty. So we can't say it won't get worse, whether other conductors have been affected and have reduced ccc, for example. Also, I think there is likelihood that additional protection for cables in walls is now kaput for that cooker circuit, for example.Not sure I understand where you're coming from.. I've done all the applicable tests, no other faults found.
