What are fuses in fuse box?

Fuses in a fuse box are protective devices that prevent electrical overloads by interrupting the flow of electricity when the current exceeds a safe level. They contain a metal strip that melts when too much current passes through, breaking the circuit and stopping the flow of electricity to prevent damage to wiring and connected devices. Once a fuse blows, it must be replaced to restore power. Fuses are an essential component of electrical safety in homes and buildings.
