One the overcurrent will disengage the trip mechanism inside the fuse. You can find out more of what we recommend on these here.Ī fuse has two ways of blowing. The best thing to do to check a fuse is to buy a small fuse checker or tester at your local hardware store or purchase it online. New fuses can trick you into thinking that they are still good when they are not. This will cause heat in the circuit and most likely a fire. If you install a larger fuse like a 20 or 30 then you were over fusing that wire. If the fuse is 15 amp then it is rated for 15 amp wire. The fuse has a rating on it for a reason. Under no circumstances should you install a larger fuse if the current fuse you have and keeps popping. Why Does My Fuse Panel Keep Blowing-Can I Install A Larger Fuse ? However the short circuit situation is very easy and kind of scary to be honest. In this case it is more difficult to tell. If you change the fuse and the power turned back on it will most likely not pop again until you reach the amperage rating or exceed it. Don’t mistake this for a fuse pop or an over current situation. This usually means a short circuit situation. Most times you can tell what causes used to blow because when you try to change it it will blow again. Why Does My Fuse Panel Keep Blowing-How Do I Find What Is Causing The Fuse To Blow? This is common in older homes with not many circuits run and you have a number of things on the same circuit lights, plugs, switches etc. In some cases when a fuse blows it will back feed through the other bar and caused multiple fuses to blow. When the fuse block bolts on to the bars it takes power from each side. There are two main bars in a fuse panel each bar has 120 volts.īetween the two bars you would have 240 volt. Some fuse panels can be a bit difficult to understand. Why Does My Fuse Panel Keep Blowing All The Other Fuses? Sometimes fuses just get tired for no reason and will blow. It can cause the fuse to blow if you exceed the rating on the fuse. This causes electricians to wire or wire in the past lights and other devices on with plugs. ![]() Often an older fuse panels, there’s not a lot of room for individual circuits. The fuse that keeps blowing with nothing plugged in may be hooked to other electrical loads that you were not aware of. Why Does My Fuse Panel Keep Blowing With Nothing Plugged In? You could also be exceeding the fuse capacity on the circuit.įor example if you have a 15 amp fuse and you were drawing close to 15 A or more than a fuse will blow.ĭo not under any circumstances with a large refusing to give you more power. In addition there may be some time a type of non-obvious load that is drawing on the fuse or exceeding the fuse capacity causing it to blow. Heat is actually the silent killer for any type of electrical source or device. The components inside the fuse panel can actually wear out which ends up causing heat. Once a fuse panel gets old or to the end of its life the components do not work as well. ![]() Your fuse panel could keep blowing the fuses due to age. ![]() Installing larger fuses can cause fire hazards. Do not under any circumstances install a larger fuse. Try to cut back on what you have plugged into the circuit or have an electrician install additional circuits. Generally your fuse panel could be blowing because you are exceeding the recommended amperage for the circuit. It can be frustrating as to why does my fuse panel keep blowing? Most cases it’s trying to tell you there is something wrong with the circuit.
