What causes short-circuiting in fuse boards?

Short-circuiting in fuse boards typically occurs when there is a fault in the wiring or appliances connected to the circuit, leading to an unintended path for the electrical current.

This can be caused by damaged insulation, loose connections, or overloaded circuits that exceed the fuse’s capacity. When the current flows through this unintended path, it generates excessive heat, which can trip the circuit breaker or blow a fuse, resulting in power outages and potential fire hazards.
