I have a kitchen with 2 sockets in it not including the cooker switch. I want to extend the ring mane and add a few more double sockets and 2 fcu's 1 for the outside light and 1 for the plinth lights.
You will require 30mA RCD protection for the new sockets and likely any newly buried cable within walls and cable routes will need to be installed within the permitted safe zones, also you will need to inspect, test and document your finding on either minor works cert or an electrical installation cert.
I have been thinking about the best way to do this.
Employ an electrician would likely be the best way!
Can I go to the socket that has 2 sets of cable running into it and take a set of the cables and put them in a new socket then add another new socket from that and so on then when I have my required amount of sockets return to the socket I originally took the cable from.
If the circuit is a true ring bothe sockets would have two sets of cables in, are sure you have ring final circuit and not a radial?
Also for the plinth lights and the outside light can I add FCU's somewhere between the new sockets. I.e, add one socket then from that add an fcu for the outside light then from that add another socket, then another, then add another FCU for the plinth lights, then add another socket, then back to original.
Once you have down-fused for lighting you would not be able to fit an additional socket, but providing you install the FCU as part of the socket circuit whether radial or ring you can install FCU along the route, but once you have down-fused typically for lighting, the fuse size will be likely to be too small to satisfy a decent load on a 13A socket outlet.
Sound complicated but I am hoping someone will be able to see what I mean. Just not sure about the FCU's,
AS above
do I run hidden sockets for the plinth lights and outside light to there own individual FCU's where I need them to be installed to switch of and on.
Ideally you would want some form of functional switching, a switched FCU could act as a method to down-fuse, isolate and as a functional switch.
But I fear that you will require some informed, experienced help, as by your post I would guess that your knowledge of circuit configuration, installation methods, compliance to wiring and building regulations and the procedures involved in certification, including inspection and testing are not as they should be if you are considering taking on the task you are inquiring about!
