If you go via an FCU, yes.

this is an fcu
because you want to use 2.5 cable you must insert a fuse to protect the new smaller cable, hence fcu, how ever you can add more sockets with no fcu if you use 4mm

no, sorry it cant becuse you will need access to it, stick with 4 mm cable

because thats not what it was designed to do. i see what you are saying though.

i agree. altho 2.5mm from a 32A ring is wrong since the breaker will only protect the cable to 32A, 5A above the limit
back to the main question, unless its the last socket you intend to take a feed from, itll be pretty tight gettin 3 4mm cables into one socket
He's quite right: there is no sense allowing a 2.5mm spur off a 32A ring and forbidding one off a 32A radial. Of course, the other conditions re spurs would apply. No further spurs off the spur. Only one socket.
There is some cable protection, because the biggest thing allowed on the end is a double socket...with two 13A fused plugs=26A
The OSG seems quite happy in principle to have unfused spurs off 32A radials wired in 4mm. Unfortunately from the wording it does not say you can use a smaller cable size. But if you use the same size cable off a radial, how is that a spur?

Thanks for the responses, maybe I should explain a little better where I am upto.
My front room had only 2 sockets in it, she who must be obeyed decided 3 more sockets were needed. I knocked out the walls and fixed in the sockets fed the 2.5mm wire down under the floor leaving plenty of spare cable to cut to size ( at this point I hadn't been under the floor). Once all the cables had been fed down I got under the floor and connected each one to the next socket where possible & jointed at a junction box where the existing cable was. Thats when I noticed the ex cable was larger 4mm, the problem I have is all the cables are installed & I have plastered up where I chased out. What next.
Someone has told me I could change the 30amp fuse in the consumer for a 20amp, is this correct.

Do not look for logic, consistency or reason in the wiring regulations. That way lies madness.breezer said:

Until of course your socket bursts into flames - you mustn't take 26A from a double socket, they are only rated at 13A.
It's not - it's called a branch, or a leg, AFAIK...
So all along, despite the fact that you were knocking holes, and chasing the walls, and you have access to the circuit cable under the floor, you planned to install these sockets as spurs, rather than properly extending the ring that I guess you assumed you had?ewanrob said:
That's pretty shabby.
