Understanding Fuses and Circuit Breakers

Fuses and circuit breakers have the same job in our Charlotte homes. When too much power is going through a circuit, they both are able to stop the flow and hopefully, stop the damage that could be caused by too much electricity going through the circuit.

Both fuses and circuit breakers have their advantages and disadvantages. Here’s a few of the differences.

Fuses

The most common type of fuses is made up of glass or ceramic with a metal casing. Inside the fuses is a filament or metal wire. When electricity is flowing normally, it safely passes through the filament and into our homes.

If a power surge occurs, the filment melts and stops the flow of electricity. Once that happens the fuse must be replaced in order for the circuit to be complete again.

Fuses react faster, but has to be replaced in order to restore power to the circuit.

Circuit Breakers

When turned on, the breaker allows power to pass across. If the current reaches an unsafe level, the switch is automatically turned off either by a magnet or a bi-metal strip, and the circuit is broken.

Circuit Breakers are much easier for the average homeowner to use. Once the problem has been found and corrected, restoring the circuit is easy as flipping the switch.
