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 home's wiring to the main power supply. It ensures that electricity is distributed safely throughout the house, powering appliances and lighting while maintaining safety standards set by organizations like the National Electrical Code.
