The damage you see could have easily been caused by a poor connection and arcing, without the need for added H2O. And without the incoming breaker/mains being tripped It sounds like one phase was lost, possibly at the service fuse outside. 60 amps is about 14 kW per phase. Thats 42 kW over 3 phases, which is 20 heaters full bore in the confined space of the switchboard. Or about the horsepower output of a Suzuki Alto at full throttle ..... However if it really "let go" in there, it's not uncommon to have fault current of 10,000 amps available, which is about 7,000 kW for a very brief period (until something trips or blows) and that is about 38 of the new Commodore V6's at full throttle. Something has to give then ...	godfather (25)
