If in any doubt on how to proceed, consult a qualified electrician.

All work carried out should comply with all applicable Wiring Regulations.

Read the instructions carefully before commencing installation. Incorrect installation will invalidate your guarantee.

Metal plate sockets and switches must be correctly earthed.

  1. Carefully slit the outer cable sheath and peel back to the required length.
  2. Remove the excess sheath and expose the underlying copper braided screen.
  3. Roll back the screen over the top of the outer sheath and trim back a short length of the inner insulation to expose the inner core.
  4. Fit the inner core to the centre (pillar type) terminal and tighten the screw.
  5. Position the section of the cable with the screen beneath the cable clamp and fully tighten the screw.
  6. Ensure that the braided screen is securely held by the cable clamp. Do not allow the braided screen to come into contact with the centre terminal.

For twin co-axial socket, each socket is connected separately in the same way.

Please Note

  • Always ensure that the mains supply has been suitably isolated before commencing installation.
  • Remove the existing socket or switch from the wall (if replacing).
  • Remove any plaster debris and dust from the inside of the wall box.
  • Always use the correct type of cable that is rated appropriately.
  • The terminal layout may vary from one socket or switch to another, therefore carefully check the location of the terminal connections before wiring.
  • For sockets and switches supplied with a clear plastic gasket, position it between the wall and the accessory. This gasket must therefore be placed over the wires before they are connected to the accessory.
  • Connect the new socket or switch as shown in the appropriate wiring diagram in these fitting instructions taking care that only the copper conductor(s) enter the terminals. It is absolutely vital that the terminal screws do not clamp on the insulation of the cables. When using multicoloured (stranded) cables make sure that after the terminals have been tightened, no stray strands are left outside the terminals. If necessary, trim and strip the cable to suit.
  • Important: Metal decorative sockets and switches must be correctly earthed. This is achieved by connecting the fixed earth wire to the earth terminal on the socket or switch and then connecting a short length of wire from this terminal to the earth terminal in the wall box. Use appropriate green/yellow sleeving if required.
