    The only breaker in metal clad that you can rack in and out that I myself have seen are either vacuum bottles or SF6 bottles. All that explosion is the arc flash, which is the copper vaporizing at over 10,000 degrees. When it vaporizes it expands at some crazy figure, over 20,000 times. There is a pressure wave that goes with it as well and can phyisically throw you.
    Check out these videos. Watch the 480 volt 3 phase arc fault. That's only 480 volts!

    Nice arcs and sparks post.

    I have heard some crazy stories about this kind of stuff from DuPont and Sunoco electricians
