One needs just 15 seconds to change the fuse and cause the dumbest tragedy. And the fire could instantly start all over the place, spreading on to the wooden frame, cutting off exits and escape routes. Over-fused circuits are often the longest and, at the same time, the most overloaded ones, going to different rooms and floors in the old house. Burning insulation will ignite an extremely dry dust inside your walls and ceiling. Too much current (or too many Amps) would flow through the wire and burn it before the fuse or breaker blows or trips. Over-fusing happens when the rating of the fuse or breaker is too large for the rated ampere capacity (or ampacity) of the circuit it is supposed to protect. If you replace a 15 Amp fuse or breaker protecting a 15 Amp circuit with a 20 Amp or 30 Amp fuse or breaker, the next thing you should do is book your own funeral.
Over-fusing is the simplest and most terrible single thing that could kill your family and burn the house.
