Okay, so you’ve got a power outage in your home, and you suspect it’s a blown fuse. Don’t panic! Changing a fuse is a relatively simple task that you can easily do yourself. Here’s a step-by-step guide to help you get the lights back on in no time:
What You’ll Need
Before you start, make sure you have these tools on hand:
- Replacement fuse of the correct amperage
- Flashlight (in case the fuse box is in a dark location)
- Screwdriver (if necessary)
How to Change a Fuse in a Fuse Box
Step 1: Safety First
Turn off the main breaker to the fuse box before you do anything else. This will prevent any electrical shocks or short circuits.
Step 2: Locate the Blown Fuse
Open the fuse box door and look for the blown fuse. A blown fuse will look different from the other fuses. It may be blackened, discolored, or have a broken filament.
Step 3: Remove the Blown Fuse
If the fuse box has screw-in fuses, use a screwdriver to unscrew the blown fuse. If the fuse box has clip-in fuses, simply pull the blown fuse straight out.
Step 4: Insert the New Fuse
Take the new fuse and insert it into the slot where the blown fuse was. Make sure the fuse is properly seated and that the amperage matches or is below the previous fuse.
Step 5: Turn on the Power
Once the new fuse is in place, turn the main breaker back on. If the fuse blows again, there may be a more serious electrical problem that requires professional attention.
Troubleshooting Tips
What if I can’t find the blown fuse?
- Check all of the fuses in the fuse box, even the ones that look okay. Sometimes a blown fuse can be hard to spot.
What if the new fuse blows immediately?
- There may be a short circuit in the electrical system. Turn off the power again and call an electrician.
What if the fuse box is hot or sparking?
- This is a dangerous situation. Turn off the power immediately and call an electrician.
Conclusion
Changing a fuse in a fuse box is a simple task that can save you money and time. By following these steps, you can easily get the power back on in your home.
If you have any other electrical problems, don’t hesitate to call a qualified electrician. They can diagnose and fix the problem safely and efficiently.

FAQ about how to change a fuse in a fuse box
What is a fuse?
A fuse is a safety device that protects electrical circuits from damage caused by overcurrent. It is a thin wire that melts and breaks the circuit when the current exceeds a certain level.
Where is the fuse box located?
The fuse box is usually located in a central location in the home, such as the basement, garage, or utility room. It may be behind a panel or door.
How do I know if a fuse is blown?
A blown fuse will have a broken wire visible inside the glass or ceramic casing. You can also check if a fuse is blown by using a multimeter to test for continuity.
What tools do I need to change a fuse?
You will need a pair of needle-nose pliers or a fuse puller to remove the old fuse and a new fuse of the correct amperage.
What amperage fuse do I need?
The correct amperage fuse for a circuit is determined by the load on the circuit. You can find the amperage rating of a circuit on the fuse box panel or in the owner’s manual for the appliance or device that is connected to the circuit.
How do I remove the old fuse?
Use the needle-nose pliers or fuse puller to gently grip the old fuse and pull it straight out of the fuse socket. Do not twist or bend the fuse.
How do I install the new fuse?
Insert the new fuse into the fuse socket, making sure that the metal ends of the fuse are making good contact with the terminals in the socket. Push the fuse in until it is fully seated.
How do I reset the fuse box?
After you have replaced the blown fuse, you may need to reset the fuse box. To do this, simply turn off the main breaker and then turn it back on.
What if the fuse blows again?
If the fuse blows again after you have replaced it, there may be a problem with the circuit. You should contact a qualified electrician to troubleshoot the problem.
