Jps1006:
Something like that happened some years ago not far from here I was told (Stratford Ont) where some siding guys pushed a scafhold into a 27.6 Kv line. Was told the fault current through the 2 workers was around the 90,000A mark, and was also told that an automatic circuit breaker / automatic re-closer DID trip but tried to reset a couple of times as its designed to do and kept belting the 2 workers that were still in contact with the scaffhold and ground.
It was the same deal with the building being built too close to an existing O/H line.
