I have a similar story, from a colleague who had worked at one of the
big accelerators in the US Argonne National Lab in the 1960s.  He worked
in the powerhouse that provided 20,000 amps at 10 volts DC to the
accelerator field coils (which were water-cooled copper then), delivered
over a par of large copper bus-bars side by side.  One day,
he happened to drop a big steel wrench across the buss bars. The wrench
evaporated with a bang, and the power system carried on. Startled but
unhurt, he called the accelerator control room and asked - they looked
and saw no indication of that momentary short.

 Cool. I wonder is there is a market for 10,000 amp pulse generators.
Sounds interesting.

Being picky, he failed to blow the 5000A fuse with a 50,000A current. He provided such current for an instant, which blew the fuse partly. In a real application, the high current would continue flowing through the other elements of the fuse, a bigger current per element than rated, and the rest of the fuse elements would blow in cascade till not one would be left alive.
