Circuit breakers and fuses are developed to prevent from an overflow of a current, ground fault and a short circuit which causes an electric fire and spoil your electronic appliances. But if circuit breakers and fuses carry out similar tasks, which one do you prefer to use?
Let’s see how of circuit breakers and fuses work
The most important difference between circuit breakers and fuses are related to their lifespan. Here once the fuse is damaged you need to replace it but in circuit breakers, you don’t need to change/replace because it operates through a switch which you can simply reset. Fuses build with a piece of metal.
When the power passes too much, the metal will melt. By obstructing the electric circuit, it prevents your electrical appliances. Once a piece of metal completely melts it has to be replaced to reconnect the connection. This feature made some homeowners to feel the hassle but, fuses are the best option to use for overcurrent protection.
Circuit breakers have metal strip or magnet in it, and it has a top and a bottom in which electricity flows through them correctly. When it feels too much current is passing, through circuit breaker the metal strip gets bent and flips the external switch or magnet becomes strong and pulls the metal liver which helps to flip the switch. When the switch flips, the current flow of circuit stops. To reconnect it all need to do is reset the switch manually. The circuit breaker is also a good option to use for preventing from the overflow of current
Advantages and disadvantages of circuit breakers and fuses.
Fuse is a less expensive device to protect from over current. It reacts quicker than the circuit breakers, and it as a hope that it won’t cause more failure than the breakers because of it as less moving parts. Whereas in circuit breakers if the inner working parts have some faulty, the damage to the electrical appliances will be more because they react slower than the fuse.
One must be careful when replacing the fuse. If you install a 30amp fuse on a 20amp circuit, it ultimately leads to cause an electric fire. Keep on replacing melted fuses can become more expensive but, in circuit breakers, you need to flip the switch. Installation of a circuit breaker is complicated and expensive and also the maintenance cost is high but in a long-term, it saves a lot of money.
