A fuse is a piece of wire made of a substance with a very low melting point. When a strong current travels across a circuit owing to overloading or a short circuit, the wires become hot and melt.
What are fuses used for?
If a failure in an appliance causes too much current to flow, the fuse trips the circuit. If something goes wrong, this safeguard both the wire and the appliance.
How do I know if a fuse has blown?
When a fuse breaks, the power to a certain circuit is instantaneously cut off. This reduces the chance of a fire and protects the wiring.
When should fuses be used?
Fuses are essential components of any electrical system because they protect the cabling of a circuit from excessive current, which can cause damage to the appliance and cause an electrical fire.
How often should I replace a fuse?
Fuses do not need to be replaced unless they have blown, thus it is not something that should be done on a regular basis.
How long do fuses last?
Fuses have a long life expectancy; fuses can last up to 20-30 years.
