The fire is non toxic. So the fuse will blow it away.
If an appliance is overheating or short-curcuiting, it could catch fire. A fuse, of the correct amps, is designed to blow before any damage is done to the appliance or cabling. A blown fuse prevents the overheating that can lead to a fire. So always use fuses of the correct amperage. This also applies to cars and their cabling, etc. the correct fuses should be given in the car's hand-book.
When an electrical fuse is overloaded, it converts the electrical energy flowing through it to heat, which melts a strip of wire in the fuse, "blowing" the fuse.
It regulates the amperage to prevent electrical overloads. If a surge occurs which is too great for the fuse to handle, it blows out, and interrupts the circuit.
You have a problem with the electrical circuit.
To prevent overloading in case of an electrical fault in the equipment.
You need to stop replacing the fuse and find out why it is blowing. It is blowing because you either have a short in the wiring, too small of a fuse, or the circuit is overloaded. If you remove the fuse then there is no danger of it catching on fire. Just make sure you do not install a larger fuse than is recommended.
The device that protects the home from the start of an electrical fire is an electrical breaker or in some older homes a fuse system.
Anytime a fuse blows, or a circuit breaker trips, indicates an excessive current [measured in Ampheres (Amps)] flowing in the circuit. This is an abnormal condition, and could be hazardous which is why fuses or circuit breakers are installed in electrical circuits. These safety devices are designed to cut off the electricity to prevent damage to the system, or in a worst case scenario, a fire. When repeated fuse blowing, or breaker tripping, occurs, you must troubleshoot the circuit to find the cause of the overload or short, and then remove/repair the cause before a new fuse can remain in place without blowing.
Which fuse is blowing - please be more specific as there are more than one fuse controlling many aspects of the car's electrical systems.
The fuse is blowing because the circuit is overloaded, there is a short in the wiring, or the fuse is too small. Be sure you use exactly the size fuse that was installed at the factory. A larger fuse may not blow but it also may cause a fire.
If a fuse in your home keeps blowing it can be caused by several things. Most often it is because that circuit is being overloaded. There is simply too many things pulling power on that circuit. It can also be caused by a short in the wiring somewhere. Can also be an appliance is defective. Can also be someone has installed a fuse that is too small for the circuit. Whatever you do, do not install a larger fuse than the circuit calls for to prevent it from blowing. The fuse is there to protect the wiring from overheating and catching on fire.
"Blowing" FusesFuses and Circuit Breakers are safety devices designed and installed in electrical circuits TO PROTECT the conductors [wires] from short circuits and overload conditions which can cause extreme overheating which can result in damage to the conductors, and worse, the possibility of a FIRE which could destroy the vehicle. When a fuse, and replacement fuses blow, especially if it happen repeatedly, is an indicator of an UNSAFE CONDITION in that circuit, usually a short. Many ignorant people will suggest installing a larger fuse to prevent blowing, but this is NOT the right thing to do and must NOT be done. Do not install a larger fuse in a misguided attempt to correct the problem. To install a larger fuse would invite damage to the wiring and an electrical system fire. The proper "fix" is for a qualified technician, who knows what he/she's doing, to troubleshoot the circuit, find and identify the defect, and make proper repair [s], BEFORE replacing the fuse again [with the properly sized fuse].
A fuse interrupts excessive current so that further damage by overheating or fire is prevented in an electrical overload or surge.
