Why Do You Need an Electric Fuse?
Fuses are used in many household appliances such as microwaves and refrigerators, as well as larger items like air conditioners and industrial equipment. If you have blown fuses in your home, you will need to take steps to replace them with new ones. The following guide will show you how to safely replace a blown fuse and get your electrical system back up and running again. 
Reasons Why a Fuse Could Blow
Should too much electricity flow through a circuit, it will cause the fuse to blow and interrupt power to that particular system. This could be because there are too many appliances or devices plugged into one outlet.
An appliance or device that has malfunctioned may be drawing more power than normal and consequently blowing the fuse.
Poorly wired outlets, loose connections, exposed wires and other types of bad wiring can contribute to a blown fuse.
Lightning hitting near an electrical box can cause surges in electricity that can overload the circuit and blow a fuse.
To prevent any further damage to your home or possessions, it is important to recognize when a fuse has blown and take steps to fix it as soon as possible. Once the cause of the fuse blowing has been addressed, use safety precautions to replace the blown fuse and restore power to the circuit. 
Steps to Fix a Fuse in a Fuse Box
- Identify the blown fuse: The initial step is to pinpoint the malfunctioning fuse. This can be determined by looking at the panel of the fuse box and locating the thin metal strip that has melted or burned through.
- Cut off power supply to fuse box: Before touching any fuses it is essential to ensure that all electricity running through the system is disconnected, as there is a risk of electric shock if not done correctly. To ensure complete safety, shut off your primary circuit breaker or switchboard to cut the mains power supply from entering into your house.
- Replace blown fuse with new one: Once you have identified and disabled power supply to your house, you can take out the blown fuse and replace it with a new one. Make sure that you use a fuse of the same rating as the original, to ensure optimal performance.

If everything is OK then you should be good to go, but if there are any issues then you will need to investigate further into possible wiring or appliance faults.
- Turn on main power supply again: After testing all electrical appliances, turn back on your main switchboard or circuit breaker and check for any problems before turning back on individual switches for different rooms in your house. This will help make sure that all power is running through the home safely and effectively.
Following these steps should help you fix a blown fuse in your fuse box quickly and easily. If you are ever unsure or worried about anything then it is best to contact a professional electrician instead to ensure safety. 
How to Tell If A Fuse Has Blown?
When a circuit breaker or fuse has blown, it is important to know how to tell. Aside from the obvious signs such as a lack of power in an appliance or other device, there are several ways to tell if a fuse is blown.
The first way to check whether a fuse has blown is by visual inspection. Look carefully at the thin filament inside the glass window of the fuse. If this filament looks broken, melted or charred, then this serves as an indication that the fuse has been compromised and needs replacement.
Alternatively, use a multimeter on its continuity setting to see if electricity flows across the terminals when connected with one another; if not, then this could also be an indication that there is something wrong with the fuse.
Finally, one can also use an ohmmeter to test a circuit breaker or fuse in order to determine whether it has been compromised. This device measures the resistance of the elements within the fuse and will indicate if there is no electricity flowing through it then it could be indicative of a blown fuse. 
How to Replace a Blown Fuse?
- Unplug the appliance or turn off the power to the circuit that is connected to the blown fuse.
- Access the fuse box and identify which fuse needs to be replaced. The blown fuse will appear discolored or melted compared to other fuses in the box.
- Take out the old fuse using a pair of needle-nose pliers, being careful not to touch any other wires or fuses in the process.
- Purchase an appropriate replacement fuse from your local hardware store, making sure it’s rated for use with your particular appliance and circuit.
- Insert new fuse into place, securing it firmly with needle-nose pliers if necessary. Sometimes, you may need to use a screwdriver to secure the fuse in place.
- Turn on the power or plug in the appliance, and test it to make sure it’s working properly. If not, then inspect your work and double-check that you have inserted the correct size of fuse.
- Dispose of old fuses responsibly by placing them inside an approved hazardous waste container or taking them to a local recycling center.
- Consult a qualified electrician if you have any doubts about your own abilities when replacing a blown fuse; electrical work can be dangerous if done incorrectly!
Types of Fuses
Fuses come in different types and sizes depending on the amount of current they are designed to carry. Common household fuses include slow-blow, fast-acting, automotive, cartridge and mini (glass tube) fuses. Each type features a specific design that is tailored to its intended use.
Slow-blow fuses, for example, are designed to withstand short surges of electrical current while a fast-acting fuse will blow at much lower levels.
Automotive fuses feature an indicator window so you can quickly check if one has blown.
Cartridge and glass tube fuses also have indicator windows but usually require a special tool to access them.
No matter what type of fuse you need to fix or replace, it’s important to make sure you’re using the correct size and amperage for the application. Using a fuse with too low of an amperage can create a dangerous situation as it will not provide the necessary protection from surges in electrical current. On the other hand, using one that is too large can cause it to blow unnecessarily and could lead to equipment damage or even a fire if left unattended.
