Very impressive, I am curious to find out what the fault current was. There is a formula for that in my ohm's law book, that uses length of the wire, size and the voltage to give you potential fault current. I do believe that there is a resistance table for lengths of wire that is needed also.
I used to know that of the top of my head, that's why this site is so great, gives me that continuing education that I need. Sure can't remember it all!
