How to wire our switches & sockets



Please read these instructions carefully before you start work. Keep them in a safe place in case you need them for future reference. You must install electrical accessories in line with the latest EE wiring regulations - BS7671: Requirements for Electrical Installations and any other relevant safety regulations.

If you have any doubts about following these instructions, you should consult a qualified electrician.

Before you start


1. Switch the mains supply off. Remove the appropriate fuse or switch off the appropriate circuit breaker.
2. Make sure that nobody else can reconnect the supply while you are working.
3.  If you are replacing an existing fitting, remove it now.
4. Clean the inside of any existing mounting box, remove any debris or dust.
5.  Make sure that any existing fixing screws are secure and do not protrude.
6. Ensure you are using the correct rating and type of cable.
7. Ensure you understand the layout of the teminal connections before wiring. They can differ between fittings.

How to wire a switch


1. Connect the wires to the accessory, following the instructions in the wiring diagram. Ensure the copper core(s) of the cable is fitted in the terminals. If necessary, strip the cable to suit. Remove any stray strands of cable. Tighten the terminal screws to secure the wires.

2. If necessary, connect the fixed earth wire to the earth terminal on the accessory. Connect a short length of wire from the accessory earth terminal in the wall box to the earth terminal on the accessory. Cover any bare earth wire with green/yellow sleeving.

3. Attach the accessory to the wall using the fixing screws provided. Make sure that the cables in the box are not trapped in any way.

4. Replace the appropriate fuse or switch on the appropriate circuit breaker. Swith on the mains isolator switch.

Wiring
All our standard dimmer switches are 250w max. trailing edge dimmers which are suitable for incandescent bulbs, good quality mains halogen bulbs and dimmable CFL bulbs. They are also suited for good quality dimmable electronic transformers and good quality dimmable LED bulbs.

Please note that our 250w trailing edge dimmers are not compatible with JCC 7w fire guard fittings, but we can supply a suitable leading edge module on request.

Our dimmer switches are 2 way, ie can be used for switching lights from either one or two places, but the other switch needs to be a standard rocker, dolly or on/off dummy dimmer switch.

1. Connect the cable as shown in the wiring diagram.
2. Carefully cut the outer cable sheath and peel it back to the required length.
3. Remove the excess outer sheath to expose the copper braided screen.
4. Roll back the screen over the top of the outer sheath. Trim back a short length of the inner insulation to expose the inner core.
5. Install the dimmers ensuring that no wires are trapped between the plate and the box.
6. Fix the plate with the screws provided. Do not overtighten the fixing screws.
7. Re-connect the power supply and test the switch.
8. It is normal for a dimmer switch to make a slight buzzing noise. This is caused by a radio interference suppression coil.

Telephone sockets
Telephone sockets

How to wire a telephone socket


1. Master telephone sockets should be fitted by an authorised engineer.
2. You can use secondary sockets to add telephone extensions. These can be wired from a master socket or from an existing secondary socket up to a maximum of 5 extension sockets.
3. This socket requires a mounting box with a minimum depth of 25mm.
4. Connect the cables as shown in the wiring diagrams.
5. Connect the terminals using 4 core telephone cable. Connect terminals 2,3,4 & 5 on the existing socket to terminals 2,3,4 & 5 on the new socket.
6. Use the same cable colour for the same terminal on each socket the actual colours are not important. Position each wire as shown in the diagram leaving 12mm overhanging. Press the wire into the connector as shown below. Remove any excess wire.
7. If the socket has a metal front plate and is fitted with earth terminals, you must connect the earth terminal on the socket fo the earth terminal in the wall box.
Co-axial wiring

How to wire a Co-Axial socket


1. Carefully cut the outer cable sheath and peel it back to the required length.
2. Remove the excess outer sheath to expose copper braided screen.
3. Roll back the screen over the top of the outer sheeth. Trim back short length of the inner insulation to expose the inner core.
4. Fit the inner core to the centre terminal and tighten the screw.
5. Position the section of cable covered with the braided screen beneath the cable clamp. Tighten the clamp screw.
6. Ensure the braided screen is securely held by the cable clamp and is in contact with the metal backing plate. Do not allow the outer braided screen to come into contact with the central terminal.
7. If the socket has a metal front plate and is fitted with earth terminals, you must connect the earth terminal on the socket to the earth terminal in the wall box. Use copper wire. If the wire is bare, cover it with green/yellow sleeving.
