Electrician Interview Question:

Breakers? Ca not I use fuses?

Submitted by: Administrator

Statistics show that fuse panels have a significantly higher
risk of causing a fire than breaker panels. This is usually
due to the fuse being loosely screwed in, or the contacts
corroding and heating up over time, or the wrong size fuse
being installed, or the proverbial "replace the fuse with a
penny" trick.

Since breakers are more permanently installed, and have better
connection mechanisms, the risk of fire is considerably less.

Fuses are prone to explode under extremely high overload. When
a fuse explodes, the metallic vapor cloud becomes a conducting
path. Result? From complete meltdown of the electrical panel,
melted service wiring, through fires in the electrical
distribution transformer and having your house burn down.
Breakers won't do this.
