Oh yes, this is a terrible problem. People backfeed into receptacles! Not only to the generators explode when power is restored but as shown they energize the low side back through the transformer and put the primary voltage on lines under repair. It has killed people. Really awful.I'll admit that one thing that never crossed my mind was someone plugging their home generator into an outlet in their home and backfeeding and energizing the primary, but it sure makes sense. And a 1500 W 120 VAC generator can still deliver a couple hundred milliamps (i.e., a few times the min lethal current) at 7200 V.
Agreed. People think of how to solve their immediate problem without considering the long range (or long reach) of their actions. I have a neighbor who at one time got so irritated with his "Check Engine Light" that he put a sticker over it. Ignoring the fact that his car was putting out excessive amounts of pollution. I'm glad he doesn't have a generator, otherwise I'm sure he would be just one such person who would back feed the grid without considering the possibility. Boy I could tell you stories of things I've seen him do. And yes, he's 100% bonafide short-sighted.It is an example of “clever” idiots.
You would think that wire would have been grounded and sparking long before the worker flipped it off the street light. Did someone else reclose the breakers manually?
