Short circuits occur when the hot wire that carries the electricity comes into contact with a neutral wire, which can cause a fire if left unaddressed.
What happens when a fuse blows?
Inside the fuse, there is a metal ribbon through which all the current on the circuit passes. The ribbon is sized to match the circuit wire gauge, and if too much current passes through the ribbon, it melts through, or "blows," and the circuit goes dead.

1. Locate the Fuse Box
Ideally, you should know where your fuse box is before your power flickers out. You typically find them in non-living spaces in your home, such as the basement, garage, hallway, utility room, or even the attic.
2. Establish Which Fuse Has Blown
When a circuit breaker trips, it’s easy to see because the switch will be in the OFF position. For a blown fuse, you have to examine each fuse in the electrical panel to identify which one is the problem.
3. Turn Off Any Appliances and Lights Attached to the Fuse
Before replacing a fuse, make sure you turn off any lights and appliances attached to it. This is so you won’t risk overloading the electrical circuit again and cause the new fuse to blow immediately. Plus, you can then gradually turn things on again, which could help identify if a particular appliance is causing the circuit overload.
4. Change the Fuse That Has Blown
Before changing any fuses, always turn off the main power to the fuse box. This prevents any electrical current from running through the panel while you’re making the change.
Fuse Size
It’s essential that you replace any fuses with a like-for-like amperage capacity. Manufacturers print the ampere rating on the fuses for ease of reference. Installing a larger capacity fuse can overheat and damage the circuit wiring, damage any attached appliances, and create a fire risk.
5. Check That the New Fuse Is Working
Once you have changed the fuse, turn the main power back on. Occasionally the panel may spark when it’s turned back on, so wearing safety glasses as an extra precaution is a good idea. Stand to the side of the box and make sure your hands are dry and you’re not standing on a wet floor.
