What Is the Difference Between a 15 Amp and 20 Fuse?

* Typically used in residential applications, such as lighting and small appliances.

* Recommended for circuits that draw less than 15 amps of current.

* Can handle a maximum of 1800 watts of power.

* May overheat and blow if overloaded.

20 Amp Fuse

* Typically used in commercial applications, such as industrial equipment and heavy-duty appliances.

* Recommended for circuits that draw between 15 and 20 amps of current.

* Can handle a maximum of 2400 watts of power.

* Less likely to overheat and blow than a 15 amp fuse.

Summary

The main difference between a 15 amp and 20 amp fuse is the amount of current they can safely handle. A 15 amp fuse is suitable for low-power applications, while a 20 amp fuse is better suited for high-power applications. Using a fuse that is too low for the amperage of the circuit can cause the fuse to overheat and blow, while using a fuse that is too high can lead to the circuit being overloaded and damaged.
