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.

∙ 6y agoFuse 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.

What type of wire is used in fuse and why?
Fuse wire is usually made with metal that has a low melting point, e.g. tin, to lessen the risk of fire.
If a oversized fuse is used instead of correct fuse what could happen to the fuse?
Using an oversized fuse can pose a fire hazard as it may not blow or disconnect the circuit in case of an electrical overload or short circuit. This can potentially lead to overheating of the circuit, damaging the equipment or even causing a fire. It is important to always use the correct fuse rating for safety.
A fuse is not used for?
A fuse is not used for increasing electrical current. Fuses are designed to protect electrical circuits by breaking the circuit when there is an overload or short circuit, preventing damage to the circuit and potential fire hazards.
Can you use a 220V 20A fuse to replace a 125V 20A?
No, it is not safe to replace a 125V 20A fuse with a 220V 20A fuse. Fuses are designed to protect electrical circuits from overloading, and using a higher voltage fuse could lead to damage or fire hazards in the circuit. Always replace a fuse with the same voltage and amperage rating as the original.
Can you use a 1.5a 125V fuse to replace a 5a 125V fuse?
No, it is not safe to replace a 5A fuse with a 1.5A fuse. The fuse rating must match the current requirements of the circuit to avoid overheating and potential fire hazards. It is important to always replace a fuse with the same or higher current rating as specified by the manufacturer.
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.
What does a microwave fuse do?
A microwave fuse does what any fuse does. It protects both the microwave and the building's electrical from surges and short-outs.
what fuse goes to dash lights on a 1991 Pontiac fire bird?
wich fuse goes to my dashboard lights on a 1991 potiac fire bird
Why is there no fire in the fuse box on the left side of a Windstar 2002?
There is no fire in the fuse box on the left side of a Windstar 2002 because there was no overflow of current.
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.
Where is the fuel pump fuse on a beretta?
there is a fuse on the fire wall ,there is constant power to a bolt with wires coming from it, under that there is a plug that is the fuse.
Where is maxifuse on 97 Ford Contour gl?
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.
What word means to fire a weapon?
To fire a weapon is to shoot, to fire, to blast, to pull the trigger, to light the fuse, etc.
