Double BT Wall Extension Socket - 4/3A

2x Circuits Wired Separately – For 2x Independent Extension Sockets 

IDC punch down terminals & instructions for easy installation. 

Extension socket size is 86mm x 86mm (fits a standard back box) and is supplied with fixing screws.

PLEASE NOTE – This listing is for 10x wall plates, multiple views may be shown in the picture above.

Used for - This BT extension socket should be connected to either a master socket or another extension socket, it cannot be used as a master socket (a master socket connects to the main cable entering a property from a telephone operator). The surface mounted faceplate can be fitted to a wall using a standard single back box & fixing screws, just like an aerial socket or power outlet. 

This wall plate has 2x separately wired sockets so you can extend 2x lines with this wall plate if you wanted to. It also allows you to wire one of the connections on the back to the first connection creating a loop, this will allow you to plug 2 phones into the same line.

How to fit - A cable should be run from the master socket or another extension socket to this socket. On the newer NTE5A master sockets there is a removable front panel where there is 3 IDC terminals, a cable can be attached using an IDC tool. The extension socket should be wired to the master socket in the following format; terminal 2 to 2, 3 to 3 and 5 to 5. If you have an older master socket, the wiring is still the same however a BT connector should be crimped onto the extension cable and this should be plugged into the front of your master socket. If you still need to use your master socket locally, you will need to purchase a BT splitter adapter. The following are all available in our shop; Telephone cable, IDC tools, BT Adapters, BT Crimper, BT Connectors. The same can be applied to the other line that runs into the building.

Can be surface or flush mounted
IDC terminal points
Fixing screws supplied

Standards - ROHS Compliant
