Tree Trimmer Crew Leader Dies When He Contacts Energized Powerline in Puerto Rico
SUMMARY
A tree trimming crew was en route to a jobsite when they noticed that trees had fallen over a 4,000-volt powerline in front of a radio tower. The damage had been caused by Hurricane Hugo. Since all the powerlines in the area had been de-energized, the crew leader decided to clear the area in front of the radio tower. The crew cut and pruned the trees to clear the area, and upon finishing, returned to the truck while the crew leader made a final inspection of the work area. Crew members heard their leader cry out and ran to the worksite, where they found him lying on his back. No vital signs could be detected. Investigation revealed that although the powerlines had been de-energized, a gas station was using a portable gas-powered electric generator to supply electrical power to the gas pumps. Since the main circuit breaker at the gas station had not been opened, electrical current from the generator flowed back through the transformer and energized the powerline at the work area. When the victim contacted the powerline, his body provided a path to ground and he was electrocuted. "

Well, you can theorize and do all the math you want, but observing the real world shows us that linemen do get killed that way.
Practice, in theory, is more important than theory, in practice.

"Lineman Killed By Generator Back Feed - Victim Helping Restore Power in Alabama
Alabama, July 14, 2005 - Sumter Electric Cooperative (SECO) officials report that a South Carolina lineman helping to restore power in Alabama after the damage caused by Hurricane Dennis was killed late Tuesday, reportedly by an improperly installed customer generator.
According to SECO Director of Public Affairs Barry Bowman, the lineman was helping to restore power lost during Hurricane Dennis to customers in Alabama. The report Bowman received indicated the lineman was working on a power line that was supposed to be dead. It was not.
Tragically, the line this technician was working on was not dead, said Bowman, The line he was trying to repair had been re-energized by a customer who had improperly hooked up a generator and created a back feed of electricity from the generator into the supposedly dead line. The death of a lineman who was there to help the victims of Hurricane Dennis was the horrible result.
Bowman noted that the linemans name was not immediately released, but he was from South Carolina and worked for Pike Electric, Inc. in North Carolina.
Alabama authorities are looking for the person responsible and indicate that charges are pending.
This could happen to any lineman, anywhere, if generators are improperly used or hooked up during a power outage. Thats why we caution homeowners and businesses about the proper use of generators. And, why we continually stress generator safety awareness with our SECO employees.I dont think anybody wants to be responsible for the death of another human being, said Bowman.
SECOs Director of Public Affairs noted that SECO also has 32 workers helping to restore power in the Panhandle and offered the following generator safety advice:
- Do not hook up (hard wire) a generator directly to your home or business electric panel. If you want to hard wire a generator to home or shop have a licensed electrician install a double-pole, double-throw transfer switch. This will assure that no back feed of electricity will travel out over a supposedly de-energized power line. The installation should meet the requirements of the National Electrical Code and local ordinances. Improper installation can result in serious injuries or deaths."

The gage that is best is the gage that will carry the ampacity of the generator. A portable power tap with breakers for each outlet that are sized to the outlets configuration is better than an ordinary "power strip."
