The answer to 'how does fuse box work' is that a fuse box, also known as a circuit breaker panel, is the main electrical distribution center for a home. It contains multiple circuit breakers or fuses that protect the electrical circuits in your home from overloads or short circuits. When too much electrical current flows through a circuit, the fuse or breaker will trip, cutting off power to that circuit to prevent a fire or damage to your electrical system.
The fuse box is typically located in the basement, garage, or utility room of a home. It contains a main breaker that controls power to the entire home, as well as individual breakers for each electrical circuit. These circuits power different areas of your home, such as lights, outlets, appliances, and HVAC systems. If a circuit becomes overloaded, the corresponding breaker will trip, shutting off power to that circuit until you reset the breaker.
