Circuit BreakersA circuit breaker is a protective device that is used to automatically interrupt the flow of electrical current in a circuit when the current exceeds a certain value. Circuit breakers are used to prevent electrical circuits from overheating and causing a fire or other damage.
Circuit breakers are typically installed in the main electrical panel of a building, and they are used to protect individual circuits or groups of circuits. When a circuit breaker senses that the current flowing through the circuit is too high, it will open the circuit, interrupting the flow of current. This prevents the circuit from overheating and potentially causing a fire.
Circuit breakers are available in a variety of different types and sizes, and they are designed to handle different levels of current. They can be manually reset by flipping a switch or pressing a button, or they may be designed to reset automatically once the current has fallen to a safe level. Circuit breakers are an important component of any electrical system, and they are required by code in many jurisdictions.
