This article covers the ways in which you can safely extend existing socket circuits to provide more outlets.
How many sockets?
Extending radial circuits
Extending ring circuits
New sockets can be added as part of the ring, or as a spur. Itsv ery much recommended to add them as part of the ring where this is practical. This means breaking the existing ring, and often adding a bit more cable.
A relatively easy way to add new sockets as part of a ring is to cut the existing cable run and fit 2 new sockets, one to each end of the cable, then link the 2 with a new piece of cable.
Sometimes running a single piece of cable from an existing point in the ciruit to a new socket is the only practical option. This is called a spur, and is subject to some limitations.
- an unfused spur should only feed one single socket
- a fused spur can feed an unlimited number of sockets. Many multi-way sockets have a fuse built in to provide the needed fusing.
Many single spurred sockets have been replaced with a double socket. This is not regs compliant, but is common.
