If you want to add an additional socket
in a room you may consider a spur from the
ring main, the only thing with a spur is,
you are limited if you ever want to add
any more sockets from the spur. You are
only allowed to spur from the ring main
once so I would always try to keep any addition
socket you require in the ring main a spur
should always be the last resort, then if
in the future you ever require any more
sockets you would be able to do so easily.
It is not really that difficult to add
additional sockets keeping them in the ring
main but keep in mind there are certain
rules you must comply by e.g the length
of cable, floor area. For more details see
ring main.
The diagrams below show how you can add
additional sockets keeping them in the ring
main using 32A junction boxes. Always remember
when using a junction box they must always
be accessible in case a fault occurs you
will need to get to it e.g under the floor
boards . There is no set limit to the number
of sockets allowed on a ring main as long
as you comply with the rules mentioned above.
When placing new cables in any floor,
void, ceiling or roof space, remember never
cover them in insulation this will make
them too hot and if you are planning on
burring them in the wall then always put
plastic channel over them for protection
and check the routing
an electrical cable page.
