rcd requirement

[manjit]

Hello just wanted to ask, my friend has done an extention, and new wiring, with new lighting, ring main, my friend has all rcbos in CU, and he has run the wiring, and contected to rcbos, but he has been told that the new wiring, i.e that the extention wiring should be rcd protercted, it dosent matter if each of the circuit is protected with rcbos,
i.e the lighting circuit is protected by rcbo and so is the ring mains and the cooker, does it still need rcd protection.
Any help would be really apprecitaed.

thank you

He says it's from solar Pannels, which it protected by an isolater, it's a flex cable

He replied to you very quickly then. Is he there with you now?

It might be but I will have to check, if 2.5 then, he will have to reduce the rcbo to 32amps, correct

Whoever is doing the work should not be doing it if they do not know whether they should have the rcs protection or not. Whether it's you or your friend. It's as simple as that.

That does indeed look like a 2.5 . oh dear oh dear , How many kw is the pv system ?

The supply tails shouldn’t be going through separate holes but that’s another discussion ?

This whole post seems a bit "fishy" but seeing as neither the installer, or the so called electrician seem to have the vaguest idea what they are on about, it's probably time to employ the services of someone who does, for safety's sake.

Incorrect, the largest the RCBO could be for 2.5 would be 20A,
