I looked in to it a bit and i see that the small HRC fuses found in good multimeters tend to have about 20kA breaking capacity. So my capacitor bank does not have nearly enough grunt to cause a genuine HRC fuse to fail catastrophically.
Issue is that you need a low voltage cap bank for the test to be valid as the fuses tend to be rated up to 400 VAC. So to get 20kA of peak current out of it the cap bank has to have both low resistance and inductance along with quite a bit of jules to sustain that for one 50Hz cycle.
If anyone thinks they have a cap bank that fits the bill id love to see some testing.
None of the 10mm ones I have seen were rated for 400V.

That large cap Photonicinduction shows to blow one apart would be the ticket. Best to know what your doing if you wanted to buy one to play with. I know my tiny half cycle generator would not come close to making any of them explode.
If I could get some of these fake Amazon fuses, these may actually come apart by the sounds of it.
