Every homeowner has experienced a sudden loss of electrical power or dysfunctional equipment at one time or another. This is a common occurrence that results from an excessive voltage that burns the fuses. Fuses are found in most home appliances especially at the head of the adapters where you connect to the wall sockets. They are meant to ensure that only steady, sufficient voltage flows through to the equipment. They burn out when sudden excessive voltage goes through them. Therefore, this is a quick guide on how to replace an electrical fuse at home.
Ensure personal safety
Wear gloves that are made from plastic and are electrically safe. This ensures that you do not risk getting an electric shock. You will realize that for the same reason, people replacing complex fuses such as that of the circuit breaker even have rubber-soled shoes. These are precautions that are essential for your safety. Also, ensure that the adapter that you are working on is not connected to the wall socket. Where possible, just detach the head containing the fuse from the equipment and work on it independently.
The covers can be removed by unscrewing gently. Detach the cover from the head and carefully note the arrangement and color of the wires. It is important so that you will return each wire to its designated place.
Identify and remove the burnt fuse
Large fuses show sign of damage through the color changes that are visible on the surface. However, the smaller counterparts do not show signs of damage. So you may be forced to perform checks to ascertain whether it has been destroyed. Pull the fuse out using your screwdriver. The fuse is simply a thin glass tube with shiny metallic ends.
Replace the fuse
Check that the fuse you intend to insert has the same amperage as the one you are removing. The fuse has no polarity, so you do not have to worry about the positions of insertion. It is highly advisable that you take your old fuse to the store so that you are given the exact one. Be sure to reconnect the wire ends the same position as they were when you opened the lid.
Return the cover
Screw the cover back on. Do it gently. Do not excessively tighten the screws so that they can be easily unscrewed next time.
If you have learned how to replace an electrical fuse at home, then you will have your equipment fully functional as fuses are parts that commonly blow out. When you are unsure about anything, always seek help from professionals.
