A power line came down on my street, and a neighbor went down and moved it out of the road. He believed it was safe, since the power was out in the houses up the line from the break. i don't know any more than he does, but my logic was, maybe there could still be enough voltage to kill a human, and maybe the transformer still has a charge, and it's just not a good idea to go near it. Now that he succeeded in moving it without a problem, he is even more convinced that he's right and I'm a big worry wart. This may be more an electrical issue than electronics, but maybe there's an EE out there willing to explain this to me.
