Sometimes, the electricity supply to our homes is irregular, and this could cause a dip or a surge in the supply to an appliance. Fortunately, the design of our domestic plugs includes built-in protection in the form of a fuse-breaker. This clever gadget protects the appliance while it’s operating – a heavy power surge will result in a blown fuse, thus preventing damage and possibly even fire.
Replacing the fuse is not a difficult task provided you have a basic knowledge of, and a healthy respect for electricity! To do this job yourself, you will need the correct-sized screw driver, pliers and of course, the replacement fuse. Check that the new fuse is suitably matched – amperage rating – to the old fuse. If this is all sounding a bit intimidating, why not find an electrician right here on Mr-Skill.
Start with safety first – isolate the circuit breaker on the mains board for the wall plugs that you plan to work on. Now you can safely remove the plug from the socket and take off its cover using your screw driver. Some plug covers are a clip-tight fit, and will need to be carefully prised open.
Look for the small glass tube inside the plug and remove the blown fuse from its cradle using the pliers. Blown ones will have a burnt or smudged appearance. Insert the new fuse into the cradle, checking to see that it is of the correct rating.
Recommendation: if your plugs are very old, you should consider getting an electrical quote to upgrade them all.
Clip or screw the plug cover firmly back in position. You are now ready to test the new fuse, so place the plug in the socket and switch on the circuit breaker on the mains board. Now switch on the appliance to check that everything is working as it should.
One of our London electricians recommends that you don’t take unnecessary risks with potentially faulty plugs. If after changing the fuse, the plug still does not work seek professional assistance instead.
