This reminds me of a slightly apocryphal story. At a telephone  
office, a fellow was servicing some equipment. Old telephone offices  
had a 48 volt backup battery supply to run the phone system. It used  
huge NiCad batteries and was distributed by large copper buss bars  
below the floor.

Anyway, this fellow had part of the floor pulled up, and he dropped a  
wrench. It just happened to fall across the buss bars, shorting out  
the 48 volt supply.

As it was described to me, the wrench melted instantly, and just kept  
on falling between the buss bars....
