Relate this incident or better one you know.
Actual Incident: A 35-year-old tree-trimming leader was electrocuted when he stepped on a downed power line during the 1989 Hurricane Hugo clean up. The line was initially de-energized but became energized when a nearby gas station used a generator to power gasoline pumps. The main breaker at the station was not opened so current from the generator fed back to the transformer, charging the line and killing the worker.
