BRITISH GENERAL NX20IL-G 20A DP Switch Wiring Accessories Instruction

Manual

1. Power Off

Before commencing work always isolate the power at the consumer unit / fuse box.

*Note – If your installation uses a four-lug metal mounting box, remove the top and bottom lugs or bend fully back.

2a. Replacing an existing accessory

1. Unscrew the accessory from the wall/mounting box.

2. Note the cable connections:
   The illustration shows 1 wire of each colour connected to each terminal.
   There should be an additional connection between the mounting box earth terminal and the accessory earth terminal.

3. Unscrew each terminal to release the wire.

2b. New installation

1. Install mounting box (metal or moulded) for either flush or surface mounting, ensuring appropriate size of product (Mounting box to be purchased separately).
2. Select the most suitable entry point of the mounting box (knock-out) and route the cables through. If a metal box is used, a cable grommet should be fitted to the entry point.
3. Cables should be prepared so a sufficient conductor length reaches the terminals. Strip the ends of the individual conductors leaving an adequate length bare to enter terminals.

3. Connection (See diagram)

1. Line up the new accessory to mounting box and take note of where each terminal is located.

2. Connect each wire to the matching terminal.
   An earth connection should always be made between the mounting box earth terminal and the accessory earth terminal, where fitted.
   All bare earth wires must be sheathed with green/yellow sleeving.
   When connecting the new accessory ensure that only the bare end of the wire enters the terminal and no bare wires are visible.

3. Tighten terminal screws securely. (Do not over tighten)

4. Complete Installation & Test

1. Carefully position the accessory into the mounting box, ensuring that no wires are trapped between the plate and the wall and secure with screws (do not over tighten) then insert screw covers (optional).
2. Once the installation has been completed correctly, replace the fuse/ reset MCB (trip), switch the power back on at the consumer unit and test.

5. Products with Cord Clamps

The flex outlet arrangement comprises a fixed portion integral to the main unit and a movable clamp portion, held in place by a screwed fixing.
The appliance cable exits through the aperture on the front/bottom face of the unit.

1. Prepare the flexible cable from the appliance as shown in the diagram.
   NOTE – The cord clamps are reversible and should be orientated to suit cable size to give proper clamping.

2. Loosen the cord grip screw fixing, remove blanking plug and pass cable
   through the aperture.

3. Connect wires as shown in diagram.

4. Adjust protrusion of cable in clamp so that wires are not taut and then fully tighten clamp to securely grip cable outer sheath. DO NOT clamp on individual wires.

IMPORTANT
The cable MUST be clamped tight on outer sheath to ensure the cable connections are not damaged or disconnected through subsequent movement of cable or appliance.

Care

To maintain the high quality appearance of decorative finish switches and sockets, BG Electrical recommend the use of a soft cloth periodically to clean the front face. When installing a decorative product please ensure that the wall is decorated, finished and free of moisture prior to installation. BG Electrical recommends avoiding using, but not restricted to, these substances from becoming in contact with the decorative metal front-plates when cleaning or decorating:

• Adhesive tape, including low tack masking tape
• Solvents
• White spirit
• Multi surface cleaners
• Industrial multipurpose cleaning wipes
• Wet wipes

Using items like those listed above may cause a degrading effect to the front- plates lacquer/plated finish, although the function will remain unaffected.
