A short in an electrical circuit could cause the cables to become red hot, causing an electrical fire. Before the cables begin to heat up, the thinner fuse wire will blow, or a breaker will trip, and the circuit will become open before any damage occurs.

Fuse wire is designed to fail if the current passing through it exceeds its rating. That means the power is cut quickly - preventing the risk of fire.

I took my car in for repairs including a new fuse. they replaced the fuse 5 times and it kept blowing. how long can you drive the car without one til it catches on fire?

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.


Can you go 20 percent higher than original fuse?

You can, but it is would increase the danger of a circuit overload. And that could cause damage to the equipment or result in a fire.


Why do schools have a fuse box?

Schools have a fuse box for the same reason that any other building that is wired for electricity would have a fuse box, which is that if the electric power usage is too heavy for the wiring, rather than allowing the wires to melt and set fire to the building, the fuse will blow (or the circuit breaker will break the circuit) and turn off the power.


When you press the switch after the fuse has melted the light bulb will not glow explain?

The fuse has disconnected the power (the wire inside melted) because the current got too high. That's why fuses are used, otherwise there is great danger of fire or electrocution with electrical faults.


What damage can be caused be replacing a 5amp fuse with a 10amp fuse?

It can cause a fire. The circuit is protected by the 5 amp fuse. This fuse is protecting the wiring in the circuit from overheating and catching fire. Install a 10 amp fuse and the protection is lost. Very dangerous to substitute a larger fuse.

Why is it dangerous to replace a fuse with a wire that bypasses the fuse?

By doing that you defeat the purpose of a fuse. The fuse is there to protect the wiring from an overload or short which could cause the wires to overheat and catch on fire. By replacing the fuse with a wire or fuse that is too large all the protection is gone and your car could catch on fire at any moment.

Depends on the purpose of the fuse. Use exactly the same size fuse as the one you remove, otherwise you may cause a fire. The fuse protects the wiring from overheating and catching fire.
