According to the Occupational Safety and Health Administration, the worker was tying up lines when he came into contact with an energized line.
Police have identified him as Dean Kitchin, 52, of Cherry Hill.
The accident happened on South Gold Drive in Hamilton Township, Mercer County early Wednesday.
First responders were called to a report of a vehicle on fire when they discovered the victim.
OSHA says he was employed by Legacy Fiber, LLC, a telecommunications contractor.
Neighboring businesses were notified in the early morning hours.
"We came in, one of my guys came in, and we all kind of headed up here this morning," said Bob Wilson, owner of Eastern High Voltage.
Wilson said his company's surveillance cameras captured what happened right behind the building and he's turned that footage over to authorities.
While he says his high voltage business wasn't involved, he says he knows the dangers of working near power lines.
"It was an accident. It was a preventable accident, it looked like from what we saw on the videos. Sad, just very sad," said Wilson.
An autopsy will be performed and police say there's no indication that there was any foul play involved.
The incident is still under investigation.
Anyone with information is asked to contact police.
Action News reached out to Legacy Fiber for comment on Wednesday afternoon, but so far we haven't heard back.
