A fuse box is an essential component of a home's electrical system. It houses fuses or circuit breakers that protect electrical circuits from overloads and short circuits. When too much current flows through a circuit, the fuse blows or the breaker trips, cutting off the electricity to prevent damage or fire. Typically located in a basement, garage, or utility room, the fuse box connects the main power supply to various circuits throughout the house. It ensures that electricity is distributed safely to appliances and outlets, making it a crucial part of home safety and electrical management.
