    I used to work at a ski resort. The snowmaking system has guns that plug into pedestals that operate at 3 phase 480vac. One night, one of the groomers dropped the grooming tiller blades right onto a pedestal and mangled/shredded the crap out of it. This did not blow the 350a breaker, and it was still arcing the next day.
