Breakers are devices used in electrical systems to protect circuits from overloads and short circuits. They automatically interrupt the flow of electricity when they detect a fault, preventing damage to appliances and reducing the risk of fires. Breakers come in various types, including circuit breakers and fuse breakers, each designed for specific applications. In homes, breakers are typically found in the electrical panel, where they control the power supply to different areas. When a breaker trips, it can be reset easily, allowing the electrical system to return to normal operation. Understanding how breakers work is essential for maintaining safety in any electrical setup.
