How to change a fuse on a plug socket ?

For a standard plug you will need a screwdriver (usually a flat headed screwdriver but will depend on the screws in that particular plug – take a look at the base).

1) In an anti-clockwise direction, loosen the screw(s) – typically this type of plug will have a larger central screw that holds the cases halves together; that’s the one to go for. You may not need to remove all the screws completely as the back of the plug should come away following a few turns of the screws.
2)Open the case and keep the back and the screw in a safe place for reinstating later.
3)Pull the fuse out, you will find the fuse within two metal holders inside the plug, sometimes these can be tight and need to be prised out, don’t worry if one of the pins lifts out with it initially – this just slides back through the case once the fuse is removed.
4)Replace the old fuse with a new fuse (making sure it’s like for like or that you really understand why it’s changing if it is).
5)It’s often worth just checking the terminals (the small screws that hold the cables in the plug) are tight at this point – a loose connection can cause overheating and an increase in current which may be why the fuse blew initially). Just try to tighten them with (usually) a small flat blade screwdriver to make sure they are nice and tight.
6)Return the lid of the plug and screw firmly. When secure there should be no movement from the metal pins that go into the wall socket.
7)If the fuse blows again, there may be an electrical fault not associated with the fuse. In this instance, we would recommend an electrician to carry out an electrical safety inspection to check the product.
