How Does Fuse Wire Protect Electrical Appliances?
A fuse is a copper or other metal wire with a low melting point that bursts due to heat-induced overvoltage or excessive load to prevent a short circuit or device failure. In electrical engineering, a fuse is a service that offers overcurrent protection for electrical circuits.
The resistance of fuse wire to the main wiring is rather high.
When the electrical current increases significantly.
The fuse wire melts to interrupt the circuit. This avoids electrical appliance damage.
Fuses are devices used to detect a short in an electrical circuit and the trip to remove that short before serious damage can occur.
This way, you don't end up with a house full of smoke and fire when your iron falls into the sink, or you forget to unplug your hairdryer. However, fuses have one major drawback: they break too easily and should not be tampered with.
Luckily, there are ways of protecting all kinds of appliances from the dangers of using fuses. The only downside to these methods is that they are not nearly as fast as fuses and take longer to detect the problem.
The most basic way of protecting a circuit is using a fuse link. The fuse link, which looks very similar to a regular fuse, is meant as a replacement for fuses.
However: it protects electrical merchandise from short circuits and overheating. However, unlike fuses, you can cut the fuse link and re-use it if it has already tripped once.
Another way to protect your appliances is by installing a circuit breaker. These devices are more expensive than fuse links and are handled differently, too.
However, they can be programmed to protect against surges in power, like blackouts (a sudden loss of power to an entire network or area) and the possibility of overloading electrical lines by using appliances like the microwave and pool pump simultaneously.
