  • Do you know these household fuse troubleshooting tips?

    A fuse is a simple but important safety device installed in your home's electrical panel. It contains a thin metal strip or wire designed to melt and break the circuit when excessive current flows. This “blown fuse” cuts off power to a specific circuit, preventing overheating, electrical fires, or damage to appliances. Fuses are commonly found in older homes, while modern systems often use circuit breakers (MCBs) or residual current devices (RCDs) for similar protection.
