How the Fuse rating is done and what are the fundamental types of fuse

1.	How the Fuse rating is done and what are the fundamental types of fuse failure?
Answer» Fuses are rated by current capacity (Amperes) and voltage. They are usually slightly larger than the required current. That is the current requirement of the equipment is 0.75 that of fuse. There are two fundamental types of fuse failure-Fatigue-cause by normal power cycling of the apparatus. This cause the fuse to heat slightly each time it is turn on which progressively weakens the fuse. Indicated by a clean operative in the fuse element/wire. Probly safe to replace the full if ensure do not replace until checked by a qualified technician Catastrophic- Caused by a fault condition of the apparatus. Indicated by severe ‘blacking’ of the fuse.
