How do I know if I have bad fuses?

Great question! If you suspect that you might have bad fuses, there are a few key signs to look out for. Firstly, if you notice that electrical appliances or lights in your home are not working properly, this could be a sign that the fuse has blown. Additionally, if you can see any discoloration or a melted appearance on the fuse itself, this is a clear indication that it needs to be replaced. To further investigate, you can use a multimeter to test the fuse for continuity. If the fuse fails the continuity test, it means that it is no longer functioning properly and should be replaced. It's important to note that attempting to replace a fuse without the proper knowledge and tools can be dangerous, so if you're unsure, it's best to consult a qualified electrician. Remember, safety first!
