The danger, on a scale from 1 to 10 is 8. Some equipment can be
damaged in a millisecond, so a slow-blown fuse can result in a ruined
piece of equipment. For example, an integrated circuit could need 12
volts, but you plug in the wrong wall wart that has no labels on it.
It has 18 volts instead of 12 volts, but it uses the same diameter
coaxial connector. A fast fuse protects in 400 microseconds, but the
slow blow does not blow that fast so the 45 nanometer digital device
gets melted in 1000 microseconds.
