Fuses have constant power because they are made of a conductive material, usually metal, that has a low resistance to electrical current. When current flows through a fuse, the resistance of the fuse material heats up the wire, which eventually melts and breaks the circuit. The size and type of fuse determines the maximum amount of current that can flow through it without causing the fuse to fail.
What is a fuse?
Fuses have constant power because they are made of a material that does not conduct electricity. This material is called an insulator. The material is wrapped around a metal wire that carries the electricity. The wire is called a conductor. The conductor is typically made of copper. The fuse is placed in a circuit so that the current can flow through the fuse and not the rest of the circuit. When the current flowing through the fuse, heating the fuse material and causing it to expand. This expansion causes the fuse to break and the current to stop flowing.

How often do fuses need to be replaced?
Fuses are an important part of any electrical system, and they need to be replaced regularly to keep the system running smoothly. Depending on the type of system and the amount of use, fuses may need to be replaced as often as every few months or as infrequently as once every few years.
Most homes have circuit breaker panels that divide the home's electrical load into different circuits. Each circuit has a fuse that protects it from overloading. When too much current flows through a circuit, the fuse "blows," or disconnects the circuit to prevent damage.
Fuses are rated by the amount of current they can safely carry. A typical household circuit is designed for 15 or 20 amps, and the fuse for that circuit should be rated for at least that much current. If a circuit is constantly overloaded, it may be time to upgrade to a higher-rated fuse.
Other factors that can shorten a fuse's life include corrosion, loose connections, and vibration. If a fuse must be frequently replaced, it's a good idea to have an electrician check the circuit to make sure there isn't a more serious problem.
What happens if a fuse is not replaced?
Fuses have constant power because they are made of a material that does not conduct electricity. This material is called an insulator. The material is wrapped around a metal wire that carries the electricity. The wire is called a conductor. The conductor is typically made of copper. The fuse is placed in a circuit so that the current can flow through the fuse and not the rest of the circuit. When the current flowing through the fuse, heating the fuse material and causing it to expand. This expansion causes the fuse to break and the current to stop flowing.
What are the consequences of a blown fuse?

Frequently Asked Questions
What are constant and switched fuses?
A constant fuse is one that lights up when the electricity supplying your circuit fails. For most homes and offices, this happens only once – in the event of a power outage. A switched fuse is exactly the opposite: it must be “switched on” by the user before it will start conducting electricity. In both cases, if the fuse's rating isn't met, the circuit breaker will kick in to interrupt the flow of current.
What kind of fuses should be in a fuse box?
There is no one answer to this question since it largely depends on your electrical needs and the number of circuits in your home or office. However, a typical fuse box will typically contain fuses for power (like those used to turn on lights or start an appliance), lighting (like those that control outlets or rooms), computers and electronics (like monitors and printers), and probably some others as well.
Why are there no switches in my Fuse Box?
A fused box does not typically have any switches in it. If you need to provide switched power to a device, you will need to locate another fuse box or source of switched power.
What is the purpose of a fuse in a car?
A fuse is used to protect the electrical system in a car during a fault. When there’s a problem with one of the circuits, the fuse will “blow” and stop the flow of electricity to that particular part of the car.
How do I know if my fuses are constant or switched?
If your fuses are switched, the fuse will light up when you tap it with a metal object – like a screwdriver. If your fuses are constant, they will only light up if you blow them out (usually by using a can of compressed air).
