Electric sockets tripping

[Lweisrick]

So I'm guessing it won't be that with what your saying?

With the current required to trip an mcb I would expect to see some serious thermal damage if the JB was the culprit, but it does appear corroded as a result of moisture so worth a shot.

what even a cheap one?

Something like this may have been happening:

A cheap what?

Like Radiohead I would expect to see visible arc damage if the fault is tripping a 32A MCB. Each time it trips there will be a flash and a bang that scorches the surrounding insulation. If there's no sign of that on the cables at the junction box, or within the junction box moulding itself, it probably isn't the culprit.

Because of the risks associated with fireworks going on inside your walls / floors, I would strongly recommend actual scientific troubleshooting rather than trial and error on this one. If it turns out to be something harmless, all well and good. But resetting the MCB and waiting for more fireworks seems a needless gamble.

One of the potential dangers of continually resetting an mcb is the high current surges can eventually blow the fault clear, leading to the impression that the problem has gone away, when in fact considerable damage has been done to the conductors at point of the fault.

OK thanks got another electrition coming tomorrow now, thanks to you all

 

[Vortigern]

@Lweisrick it would be interesting to know what the problem turns out to be.

I will keep you all informed ?
