Fitting a new plug
Topic: General DIY Author: Paul Cameron

The colours of wire used in flex should be Blue for Neutral (N), Brown for Live (L), and Green and Yellow for Earth (E), this is the current standard and has been so for many years. However the previous standard is sometimes encountered and this is Black for Neutral (N), Red for Live (L), and Green for Earth (E).

New electrical products should come fitted with a plug. Plugs sometimes need attention because they become damaged, and a damaged plug should be changed immediately as it poses a safety risk.

Fitting a new plug
 

Unscrew the new plug and remove the cover. The terminal on the bottom right next should be connected to the Live (Brown) cable. The left hand terminal should be connected to the Neutral (Blue) cable. Finally the top terminal should be connected to the Earth (Green and yellow) cable.

 

A simple way to remember the correct positions of the wires is:

 

BL - Bottom Left - BLue
BR - Bottom Right – Brown

 

After connecting the wires, the flex cable should be clamped in place using the cable grip at the bottom of the plug.

The cable grip is sometimes a screw down clamp and in other cases the plug has two flanges which the cable should be pushed into to make it secure. It is very important that the cable flex is secured in this way to make the plug safe.

The device, to which you are fitting a plug to, usually has an Earth wire (Green and Yellow).

 

Finally, replace the plug cover and that’s that.

 

Most modern new appliances now come with a moulded plug which can not be opened.
