voltage
The fuse "blows" when the current carried exceeds the rated value for an excessive time. The higher the overload the shorter the period before the fuse blows. So, equipment which is meant to "draw" 10 amps but which has a short from phase to ground, so it draws, say, 100 amps, will blow its fuse in milliseconds.

Why does my Central A/C Keeps Blowing its Fuse?
For years, my A/C condensing unit has blown a fuse once, maybe twice a year. It''s 27 years old now and blew a few fuses last spring. Now it blows a fuse every few days. So, I replaced a bad running capacitor on the compressor and replaced a leaking capacitor on the condenser fan motor, still blows fuses every few days.
Was attempting to fix a home theatre subwoofer. Fuse was
I mean, trying to feed AC power to the DC bus is blowing fuses and has destroyed at least one component. Capacitors don''t like having their voltage threshold exceeded (thus one went kaboom) and polarized capacitors *really* don''t like having the wrong polarity fed to them.
