Adding more sockets with FCU

[BegBorrowSteal]

Hello, I’m wanting to add more sockets to my bedroom and dining room three doubles in each room can I add a FCU to a socket in each room and add the sockets that way or is this a bad idea?

I have a ring main running a 30a fuse for all sockets in the house as it’s a old cartridge type CU.

Thanks

Yes -

but new sockets should be 'protected' by an RCD, so you could fit an RCD FCU - or fit a stand-alone RCD next to the fuse box which would 'protect' all the sockets on the circuit, although you would still need the FCU for more than one socket on a 2.5mm² cable spur.

If you use 4mm² cable for the spur then the FCU is not required but the RCD would be.

Thanks I’m getting the CU replaced in two weeks so it will have RCDs for my handy work to be protected. Thanks again

Can you not just 'extend' the ring, so you don't need the FCU?
