Replacing a fuse in an electrical plug is a handy skill to have for maintaining the health of your electrical devices. It is similar to changing a lightbulb and can be done at home with relative ease. However, it is important to exercise caution as mistakes can lead to dangerous outcomes. Before attempting to remove a fuse, ensure that all electrical devices are switched off and unplugged. This will prevent electric shocks and potential fires. In this guide, we will cover the steps to safely remove a fuse from an electrical plug and provide tips to avoid common pitfalls.

What You'll Learn
Ensure all electrical devices are switched off and unplugged
When removing a fuse from an electrical plug, it is essential to prioritise safety. Before beginning any maintenance work, ensure that all electrical devices are switched off and unplugged. This precaution is not just about avoiding electric shocks; it is also crucial for preventing potential fires.
To ensure your safety, it is recommended to wear protective gear, including keeping your hands dry and wearing rubber gloves and rubber-soled shoes. These measures will safeguard you from potential electrical hazards. It is also important to determine the type of plug you are working with. A moulded plug usually has a pop-out fuse holder between the pins, while a standard plastic plug typically has the fuse internally mounted and will need to be opened.
Before attempting to remove the fuse, make sure that the plug is disconnected from the mains power supply. This step is crucial for your protection. Once the plug is disconnected, you can proceed with removing the fuse. The fuse is typically located within two metal holders inside the plug and can be carefully pulled out. If the metal holders are tight, you may need to gently prise them out. Don't be concerned if one of the pins comes out with the fuse, as this can be easily slid back into place once the fuse is removed.
After successfully removing the fuse, it is important to address the underlying reason for its malfunction. A blown fuse could indicate a deeper electrical problem. If the fuse has blown due to an issue with the appliance itself, replacing it with a like-for-like fuse of the same specifications is recommended. It is important to avoid the temptation to replace it with a larger fuse, as this could lead to dangerous consequences, such as fires or electrocution.

Wear protective gear, including rubber gloves and shoes
When removing a fuse from an electrical plug, it is important to wear protective gear, including rubber gloves and shoes. This is because rubber is an extremely poor conductor of electricity, so it prevents electric currents from passing through it. Rubber gloves act as a protective barrier, shielding your hands from electrical shocks, burns, and other injuries. They also protect against harmful chemicals and other hazardous substances.
It is important to choose the right class of gloves based on the specific electrical work and the voltage exposure involved. For example, Class 00 gloves are suitable for low-voltage applications, offering protection up to a maximum voltage of 500V (AC) and 750V (DC). Class 0 gloves provide increased protection for higher voltage environments, with a maximum voltage rating of 1000V (AC) and 1500V (DC). For even higher voltage environments, Class 1 gloves are recommended, with a maximum AC voltage of 7,500 volts and a DC voltage of 11,250 volts.
In addition to gloves, rubber-soled shoes or boots are also necessary to prevent electrical currents from conducting through your feet. It is important to consider the surface you are standing on and the type of shoes you are wearing, as this can impact your safety when working with electricity.
By wearing the appropriate protective gear, you can ensure your safety and mitigate the risks associated with electrical work.

Identify the type of plug and fuse
Before removing and replacing a fuse, it is important to identify the type of plug and fuse you are dealing with. Firstly, ensure that all electrical devices are switched off and unplugged. This is crucial for safety and to prevent potential fires.
There are two common types of plugs: a moulded plug and a standard plastic plug. A moulded plug usually has a pop-out fuse holder between the pins, which can be easily accessed with a small, flat-bladed screwdriver. On the other hand, a standard plastic plug typically has the fuse internally mounted, requiring you to open it up.
Fuses come in different ratings, which correspond to the amount of current they can safely handle. In the UK, common fuse ratings include 3A (red), 5A (black), and 13A (brown). Fuses for 3-pin plugs may vary in rating but are typically the same physical size.
When identifying the type of fuse, look for the rating marked on the fuse itself. It is important to replace a fuse with one of the same rating and specification to avoid potential electrical hazards.

Remove the fuse with a screwdriver
Before you begin, ensure that all electrical devices are switched off and unplugged. It is important to wear protective gear, such as rubber gloves and rubber-soled shoes. The main tool you will need is a screwdriver. The type of screwdriver you use will depend on the type of plug you have. A moulded plug usually has a pop-out fuse holder between the pins, which can be popped out using a small flat-bladed screwdriver. A standard plastic plug typically has the fuse internally mounted and needs to be opened up with a screwdriver.
To remove the fuse with a screwdriver, first identify the type of plug you have. If you have a moulded plug, insert the screwdriver into the fuse holder and gently prise it out. If your plug is plastic, you will need to use the screwdriver to open it up and access the fuse. Once you have located the fuse, carefully insert the screwdriver into the appropriate slot and gently lever the fuse out. You may need to apply a small amount of force to remove it, but be careful not to damage the fuse or the plug.
If the fuse is tight, don't worry if one of the pins lifts out with it. Simply slide it back through the case once the fuse is removed. Once the fuse is out, you can replace it with a new one, ensuring it is the same type and rating as the one you removed. It is important to check the terminals at this point to ensure they are tight. You can do this by using a small flat-blade screwdriver to tighten the small screws that hold the cables in the plug.
After replacing the fuse, reattach the fuse cover or the plug's cover. If you unscrewed the cover, make sure it is screwed back on securely. Once everything is in place, you can plug in the appliance and test it to ensure it is working properly.

Test the appliance after replacing the fuse
Once you have replaced the fuse, it is important to test the appliance to ensure it is working properly. Here is a step-by-step guide to testing an appliance after replacing the fuse:
Firstly, ensure that everything is securely in place. If you had to unscrew the fuse cover or the plug's cover, make sure it is screwed back on correctly.
Next, plug the appliance into a power outlet. If the appliance has a separate power switch, turn it on. Check if the appliance is functioning as expected. For example, if it is a lamp, turn it on to see if the bulb illuminates.
If the appliance works, great! You have successfully replaced the fuse. However, if the appliance still does not work, there may be a deeper electrical problem. A blown fuse can sometimes indicate an underlying issue with the electrical circuit or the appliance itself.
In such cases, it is recommended to seek professional help. Contact a qualified electrician to inspect the appliance and identify any potential electrical faults. They will be able to advise on any necessary repairs or replacements to ensure your appliance is safe to use.
It is important to prioritize safety when dealing with electrical appliances. If you are ever unsure about the process or feel uncomfortable, do not hesitate to consult a local electrician for assistance.
