Mike,
I was called back to a job where I had done a Service change/relocation. The person had added an extension on a slab over the original UG service so it had to be re-routed around it. The contractor had removed the sill plate to put siding on and when he put it back he put a screw through the cable.
When I got there (about 15 min later) it was still shooting sparks and flames every minute or so. I told him I wasn't going near it. When POCO came and disconnected so I could fix it they would not reconnect without inspecting a good portion of the buried cable. They did reconnect, but because of some damage to the transformer some houses on that block only had one leg (120v) for a few days.
The contractor went to the hospital for tests and was released, - a lucky guy!
