What is the difference between a circuit breaker and a fuse?
A. A circuit breaker and a fuse both perform the same function, interrupting the flow of electricity when a fault is sensed in an electric circuit. Fuses are cheaper to install, but not as efficient in the long run. Circuit breakers can be reset without having to replace anything, but fuses must be replaced when they trip. Today circuit breakers are economical and are used in most modern applications due to their ease of use.
