    Hi,
    I found a spur of a spur in my house while refurbishing the kitchen.... I think this could be easily fixed.
    There was a double socket that I removed. There is one wire coming down from the main ring (white). Wired on to it there was another spur with more recent cable (grey). That one goes in to a socket behind the cabinets for the dishwasher.
    I was thinking of just wiring both cables together and put a blanking plate where the double socket was, and turn it in to a single spur feeding the dishwasher. However having one socket there would be nice. As I think we can wire a double socket of a spur I think that should be possible?. If I put something like a cooker switch + socket 2 gang terminal, would that still be acceptable? Technically I only need it to be 13A, so not sure I can put a cooker socket or if they do something similar with 13 amp. otherwise I was thinking of putting back the normal double socket, taking the grey cable out of the box and connect it to one of the two sockets with a standard plug. That way it just a normal double socket spur, with the dishwasher connected to one of them using the grey cable as an extension... I think it will look a bit odd with the wire coming of the wall... I do not think it will ever get overloaded even if left as it was, but I prefer to make things right when possible. Any other available solutions anyone?
    Thanks

    is the white wire from the ring thicker? If it is. it's not really an issue.

    A cooker switch with socket won’t fix things. Your under worktop socket would still be a spur off a spur.

    At your (removed) socket position. Change the back box to a dual box.
    In that put an FCU fused at 13A and a single socket. Connect the cable fyom the ring to the feed side.
    To the load side of the FCU, connect the
    under worktop socket And The new single socket outlet.

    I think what Andy was thinking/suggesting/implying was that the white cable (from the ring) looks as if it might be 4mm² (or equivalent). If so, then, as he says, there's nothing wrong with the present 'spur off a spur' situation.

    It may, of course, be an 'optical illusion', with both cables being 2.5mm² (or equivalent).

    Kind Regards, John

    Both cables are 2.5mm². The dual box with an FCU fused at 13A and a single socket as TTC suggests seems the way to go.
    Do you know if there are any brands that sell that already made as a single plate for a 2 gang box? otherwise upgrading to a dual box should not be an issue
    Thanks!

    Fair enough. Do I take it that it wouldn't be straightford to replace the feed from the ring - because, as said, if that were upgraded to 4mm that would be all that would be needed.
    I don't think you'll find such an animal, per se. However, you may well be able to do it with 'modular' accessories (i.e. a plate with a fuse module and a socket module).

    Kind Regards, John

    This IMGP7387.jpg was how I got around the problem, LAP grid system done by screwfix allows one to have a fuse and socket in a double socket plate.

    Thanks Eric!
    That is great, and saves me having to change the box and making a bigger hole. I will look in to that grid system

    As you now have only two single sockets on the spur, the 13A fuse isn't required as far as electrical considerations are concerned.

    It's just that there is an unnecessary sentence, in the regulations but not actually a regulation, in a sample diagram of circuits which, for some unknown reason, states that only one socket shall be on a 2.5mm² spur, but that socket may be a double one.
