Hi,
I have a ring main in my kitchen with 7 double sockets with a spur for an under unit light. My questions is can I take a spur off 2 of the double sockets to create 2 more double sockets?
The ring main goes back to my consumer unit which has a 32 amp fuse.
I need the spurs to relocate some of my applicence therefore not all of the sockets will be used at the same time.
Any advice will be appreciated.
Cheers,
James

As I understand it, you can only have a single fitting off a spur. So /two/ double sockets on one spur is out.
One double on each of two different sockets should be OK.
The latter is what I understood to be the OP's intention ...

I thought so too - which was why mentioned it!
All seems a bit silly these days when most people have at least a dozen things plugged in behind their tv and computer

Ah, but that's done with dodgy socket strips, so it's OK.
But they /are/ protected by a 13a (or lower) fuse. Several sockets loaded to
3kw on a spur with 2.5mm wiring will overload the fixed wiring.The message from contains these words:
Shouldn't do - that's what the 32A breaker in the fusebox is for!
Dodgy? Pish and tush, Sir, I have splendid Olson strips in my study. 3 x 12 way ones.
That's not OK, then. You have to use dodgy ones!
Two double sockets with 3 outlets loaded to 3 kw will put ~36A on the 2.5mm cable, well above it's required capacity of 20A. a 32A breaker is unlikely to trip for a looooong time, leading to damaged fixed wiring.
The message from Guy King contains these words:
But the spur is in effect a radial circuit and radials in 2.5mm have 20A MCBs.
The message from contains these words:
Sorry, I thought we were talking about a ring circuit. Yes, on a spur it will - but that's why you're not allowed more than one double socket on a spur!
What about a switched fused spur?
Yes this is what I was looking to do. One double as a spur off of two different sockets on the ring main.
Cheers for all the comments,
James
You can have as many sockets as you like on a fused spur, provided you don't expect the total load to exceed 13 A.
Of course, if they are not far apart, and it's easy to run a cable between them, just incorporate them into the ring...

Then that part of the circuit changes from an unfused spur to a fused spur. On a fused spur one can do all sorts of things that are not allowed on an unfused spur.
Of course on a fused spur one must put one's finger in the air and evaluate the likely diversity of loads on the spur. Otherwise it may become something of a nuisance when the protective device operates frequently. One also has to look at issues of the earth loop impedance of the cable size.
