From what you've said here, and what you said in your original post, I think you need to get a competent electrician to inspect & test this circuit. Its possible that circuit in question was originally installed a as Ring circuit, and either has become faulty or was not correctly installed in the first place. It sounds as if the property has been renovated and in the process rewired.Hi all,
Thanks for the welcomes and the advice.
In response to posts 4 & 6, it is definitely 2.5mm twin + earth.
It is not actually a new-build house, but the place had been completely renovated when I bought it and this circuit is in a fairly new extension.
There are two conductors in the MCB; It looks to me as though there used to be a ring around what used to be the kitchen, but when the extension has been done the ring has been broken into two radials, one going to the kitchen and the other to the utility room, and the two ends have not been connected back together to form the ring.
The overall floor area served by the circuit is slightly less than the 50m^2 stated in the regs. It seems to me that, with the 20A MCB in place, it is now safe. I plan to just leave it and see if the MCB starts tripping. If it does then I think I'll need to get a guy in to install a proper ring.
You originally said the RCD was tripping, suggesting some kind of fault. The only way to investigate this is by testing, this will also clarify whether the circuit is an RFC or two radials in one MCB.
If the original installer cannot be located, then I would suggest using the services of a local electrician.
