Brief Description of Incident:
While a line crew was removing a hot line clamp connector on energized #6 solid copper wire, the wire broke, landing on the phone line.
The center phase fuse blew and the wire down remained hot due to backfeed. It was discussed that wire damage cannot always be seen under a hot line tap, but we need to remain aware of the potential for wire to break, especially copper wire.
Contributing factors: Complacency/Overconfidence, unfamiliar with task (training), hazardous attitude toward task, unexpected equipment conditions
