Hi

I am helping out installing a new socket

The existing socket is a trip base dual domestic socket. Its part of a
ring main which has 2.5 twin core and earth.

I presume an rcd socket on a 2.5mm T&E ring circuit.


I need to run a socket for to the middle of the room (i have done this
as a test - the breaker came on .. then about 5 minutes it tripped -
what could be the cause of this)

do you mean the breaker on the socket itself? If so, a fault in
whatever was plugged into it will normally be the cause. If nothing
was plugged in, its either wet, really filthy or faulty.


Firstly should i run 2.5 twin core and earth.. or can i get away with
1.5mm *?

2.5 really. You should get away with 1.5, but much better to keep it
legit.


I also saw on a website it would be all right just to run a single
cable instead of running a ring back... ?

you can connect it as a spur. But if a ring is also doable its the
better option.


Finally should i remove the trip socket to the end of this line .. and
just put a normal face plate / blanking plate across this unused
socket.

I dont see any reason to, what do you want to do?


What advice can people provide on the above as I would like to get
this resolved

we need more detailed description, something somewhere tripped is too
vague.
