The answer to 'circuit breaker vs fuse' is that circuit breakers and fuses are both electrical safety devices used to protect wiring and equipment from overloads and short circuits. However, they have some key differences in their features, benefits, and use cases.
Circuit breakers are reusable devices that can be reset after tripping, while fuses are one-time devices that need to be replaced. Circuit breakers generally cost more upfront but can save money in the long run by avoiding the need to constantly replace fuses. Fuses are often better suited for temporary or portable applications, while circuit breakers are more commonly used in permanent electrical systems like homes and businesses.
