How To Change A Plug’s Fuse

Fuses come in three common ratings: 3A, 5A, 13A. Each will be the same length physically but coloured to match their power rating. 3A is red, 5A black and 13A brown.

When replacing a fuse, always replace like for like. Do not remove a brown 13A fuse with a 3A red one. Failure to do so can result in your electronic item not working or even worse, becoming faulty & dangerous.

To change a fuse, you will need a flat headed screwdriver (with a flat | point), or a Pozidriv (a screwdriver with a + point at the end). Obviously the screwdriver you will need has to fit the screws in the plug!

In an anti-clockwise direction, loosen the screws. You may find you don’t need to remove all of the screws completely as the back of the plug will come away following a few turns of the screws.

Inside the plug, you will find the fuse clamped into two metal holders. Pull the fuse out and replace with the brand new fuse. Again, make sure to replace 3A with a new 3A, 5A with a new 5A etc.

Replace the lid of the plug and screw tightly again. You will know when it is tight as there should be no movement from the metal pins that go into the wall socket.

If you find that the fuse blows again, it is likely a sign that the electrical equipment is at fault, and not the fuse. In this instance, it might be worthwhile having an electrical safety inspection. Consult your manufacturer instructions or a local electrician for further information on this.
