micc on rcbo will not set

Used MICC in Council new build flats in the 60s (1960s for the comedians out there)

Yep, the old council spec was mostly either steel conduit or micc both for the flats and communal areas on the local authority where I used to work.

Nowadays its thrown in, cheap and work that a bloke pulled off the street could put his hand to in a day. ​

when back to day to look at the job.on to test the micc the reading went mental on IR
looked at the bathroom enclosed light the bowl was full of water & the base
the only thing was missing a gold fish . found out the flat above had a leek
went to the flat below

Translation probably something like:

Went back today to look at the job again. Ran IR test on the MICC but the reading was low. Found a bathroom light that was full of water from the flat above causing the fault. Problem solved, thanks for your input everybody.

I think hightower has probably got it spot on there. Daz

Only thing I can't figure out mate, is where the leeks come in to it?

I wonder if the property is in Wales.

So the RCBO was doing the job it was designed for I wondow how long the MCB would of held before it went bang!
Surprised that the IR test didnt reveal leakage I am surpised re the readings (IR)that were posted!

Thanks for the translation Hightower !!!

Must agree the IR must have been low anyway, init.

That's why I was confused at #49.

Jeez this is alarming. Wouldn't you investigate the said lights on the circuit? Maybe open them up for a visual at least. From my experience with Pyro i guarantee the OP has taken a initial IR reading and has not left the meter on long enough to establish a stable reading. MICC can jump sporadically. Then stabilise with resistance going higher or slowly moving gradually lower which would concern me if it fell below the required value.

Buzz is alarming.

How right you are
