What happens if a fuse is blown?

A blown fuse occurs when too much electrical current flows through the circuit, causing it to overheat and melt. This can happen due to an overload of appliances or faulty wiring. To replace a blown fuse, you will need to first locate the circuit breaker panel in your home.

Can a blown fuse be switched back on?

Fuse boxes are also found in low-traffic, discreet areas just like breaker boxes (utility closets, garages, basements, etc.). Unlike a circuit breaker, a blown fuse can’t be switched back on. To fix it, you will need to replace the fuse with one of the same amperage rating (more on this below).

How do you replace a blown fuse in an electrical panel?

Modern electrical panels use circuit breakers instead of fuses. When an overload occurs, the breaker “trips” (shuts off). You don’t technically replace a blown fuse in this system, but rather reset the breaker or, in some cases, replace a faulty breaker. Open the main electrical panel door.
