A 33-year-old water well contractor was electrocuted when a metal pipe lifted by a truck-mounted crane contacted a 12,000-volt overhead power line. The victim and a coworker were repairing a submersible pump for a water well at a private residence.The well was located in a pasture with three parallel power lines overhead. One of the power lines passed directly over the well, 32 feet above the ground. On the day of the incident, the victim positioned the truck-mounted crane beneath the power line.
