    Anyhow, here’s what an Arc flash of the power they are playing with will do to your body. Don’t worry, nothing gruesome to see as the body is atomized.

On AC power if the fuse opens as the current rises up the sine wave the energy released is the area under a tiny portion of the curve. If the fuse takes a 1/10 of a second or 6 cycles to open the energy under the curve is huge and will destroy the equipment. Fuses like this are used as a backup to circuit breakers because a circuit breaker simply isn’t fast enough to limit the peak current.

    Those links? There is a good chance they were pure silver!
    Well, his video does have over 3 million views, there’s a chance the fuse paid for itself plus more.

    He routinely does his experiments in the house on carpet,
    interesting to say the least. I fully predict this house burns
    down some day.

    Why does the explosion look fake???

    I believe he works on high power radar from memory, some defence stuff at least, I certainly wouldn’t muck round with 1000amp Mercury arc rectifiers and such in what looks like my lounge, slightly insane imho, certainly gets your attention

    Obviously. Or, at least I assume that's why you posted it. I meant no criticism of the fact the link was posted, rather just the length.

    The topic did look interesting to me; that's why I clicked on it. I might have found it interesting, but probably not 18+ minutes worth of interesting.

    I appreciate your point of view about being safe. I really do.
    But you can't save the world.
    Do you appreciate my point of view?
    If you worried about all the dangerous stuff on youtube
    you don't have enough years in your life to do that.
    I think it is fighting a loosing battle to be cry safety about a youtube video.
    Again, just my opinion. You obviously feel differently and will continue on your quest.

    The good news is that with that particular situation, if the flying debris does not gitcha, there is no prolonged arc, since he has a limited energy supply in the capacitor bank.

    I did notice he had the capacitors shorted, a good plan due to potential voltage buildup from "dielectric absorption". Use of a remote switch, etc, all good things. No clue about the surroundings and spectators,

    Of course, if the fuse does open, the remaining energy in the capacitor may mean there is a residual voltage. He made no comments about precautions that I noticed, but I admit I skipped through, not wanting to listen to every word. Might have been in the parts I skipped over.

    Anyone can explain the PURPOSE of the experiment?

    P.S. I also wonder what diagnosis his psychologist deals with...
    P.P.S. But I should add that wasting 18min of our life to watch this is also a sign of a problem.

    Yes, they would protect you from the vast majority of electrical arcs but I suspect there's always going to be some that they wouldn't...like a lightning strike for example. They shield you from the initial blast of heat and projected molten metal and give you that small bit of time to save yourself.

    If he blows himself up, it will likely be documented on video.
    Perfect training video footage.
