Extra sockets but with a couple of issues

[BrianAH]

Picked up some great points from other posts, and have put together the following plan from those which I THINK is ok, but would welcome some comment and hopefully thumbs up.....

[RCD ring main (too short)] > [ADD junction box to extend the two ring main cables by 0.5m] > [wire in an FCU with 13amp] > [two new spurs each to a double socket each approx 0.5m from FCU]

See this below in diagram form (since it doesn't quite come out as I intended - note that the ring main indicated thus || feeds from the skirting into the new Junction box and then to the FCU....with a left and right spur.

SPUR 1 <<<<<<<|NEW FCU|>>>>>>SPUR 2
||
||
||
NEW Junction Box
||
||
||
<<< SKIRTING >>>

The actual load will be:
Spur 1 - Microwave and Kettle or Coffee Machine
Spur 2 - Fridge/Freezer and Washing Machine

This is part of our new kitchen fit that I am doing myself as I can't afford the installation costs. I will be SO grateful for any feedback on this please. Thanks - Brian[/u]

The way I read your drawing you are not extending a ring final circuit but adding a spur upon a spur which you cannot do.

Also with the proposed layout and the anticipated load you board will be tripping away.

Finally, this work is notifiable to the Local Authority Building Control and you should contact them before work commences.

Why make the new sockets spurs?
If the cable you intend intercepting is part a ring, Why not make the new sockets part of the ring too by pulling back (or replacing) the wiring between the existing socket to your first new socket, a new cable to the second new socket, and one back to the other existing socket? No need for a juction box or FCU then.

But note what riveralt has already said about the loading, and notification.

Also consider the 'safe zones' for cabling. Concealing wiring behind a skirting board is bad, even dangerous practise.

Although many may disagree with the requirement to notify, and the costs involved, it is a legal requirement.
