Taking power from a 13amp socket

[banjodeano]

Hiya guys,
i am wanting to take a spur off a socket in the bedroom, there is only one socket in the room and i wanted to create another one, when i took the cover off there are three wires going into each connection, one of them has been used to take power into the adjoining bedroom for a socket, would it be possible to take power from the first socket again? and if so, is it possible to get four wires into each terminal? if not is it possible to get sockets with large terminals? the sockets in both rooms are not in use,
Thank in advance

It is nearly always possible to get four 2.5mm2 cables in the terminals of a standard 13amp socket.

4 wires is not a very nice job for a DIYer though!

But if the 3 have been put in well, you stand a chance

Remove them, then, and it might make the job easier.
