Fitting Extra Telephone Sockets

Page: 1-2-3-4-5-6-7-8-9 Print this page
There are two possible basic circuits for installing additional telephone sockets:

1 Spur wiring - where the adapter connected to the master socket goes to a junction box and then each socket is wired from the junction box (as below).

2 Series wiring where the adapter connected to the master socket is wired to the first socket, which is wired to the second socket, which is wired to the third socket and so on (as below).

The choice of which is used will depend upon the position of the master socket and the required positions for the new sockets. You can mix the two forms as necessary, possibly using serial wiring to connect junction boxes on each floor, and then running spurs from each junction box to the socket positions on each floor.
