​Changing a 2-pin to a three-pin plug

Ever wondered how you can change a two-pin plug into a three-pin plug? We have the step-by-step instructions on how to do this in a safe way.

What you will need

  • New three-pin plug
  • Small screw driver
  • Side cutter or craft knife

Step-by-step instructions

  1. Safety first - Make sure that the appliance is not plugged into electricity. It is important to never modify electrical elements whilst they are plugged into electricity.
  2. Remove the two-pin plug using a side cutter to cut it off just above the top of the plug. You will notice that there are two wires inside the electrical cord, a blue and a brown one.
  3. Making use of the side-cutter again, first bare the cord to expose the wires inside about 1.5 cm. Note that if you cut into either the blue or brown wire, you need to do this process again a bit higher up on the cord, to ensure that you keep the cord safe for use.

  1. Next, bare the ends of the two wires inside the electrical cord about 0.5 cm, by cutting away the plastic insulation. Proceed to gently twist each strands of copper wire with your fingers until each of them is tight, folding them away from each other.

  1. Remove the plug cover by unscrewing it using a screwdriver or if it is a ‘Snapper’ plug you un-snap it by pressing in a screw driver into the middle of the plug to release the snap mechanism.

  1. Unscrew the little screws on each of the plug's pins a little.
  2. Insert the twisted copper wires into the holes in the pins as follows - The blue wire is inserted into the left pin (the pin is marked with a blue spot or the letter Neutral). The brown wire is inserted into the right pin (the pin is marked with a brown spot or the letter Live)


  1. Tighten the little screw on each of the plug's pins to secure the wires inside. Tug on them gently to make sure that they are fastened properly.
  1. Make sure the electrical cord is firmly gripped by the arrestor clips and replace the cover of the plug, fastening it with a screw and screwdriver. The ‘Snapper’ plugs just click into position.
  1. Test the appliance to see if the plug is working.
Note that if you replace a three-pin plug with a new three-pin plug the process is exactly the same, the third wire which is green and yellow gets wired into the top pin (Earth).
