Circuit Breaker
A Circuit Breaker is a crucial safety device that automatically stops the flow of electricity when there's a problem, much like a safety switch. Think of it as a guard that protects electrical equipment and buildings from damage due to power issues. Unlike regular switches that just turn power on and off, circuit breakers can detect problems like overloads or short circuits and respond automatically. They come in many sizes, from small ones used in homes to massive ones used in power stations. In job descriptions, this term often appears when companies are looking for people who can install, maintain, or design systems that include these safety devices.
