This fascinated me. I thought the group might enjoy it.
A tree branch took out a service drop, pulling the riser and the trough off the building. Aluminum siding!!!
It’s a 200A 3-Ø Commercial service with 3/0 cu. Steel raceway to the weather head, the trough is pulled off and it is visible hanging over the Gas Meter and Vent. The fire dept shut down a two lane state highway. And stood back until the utility arrived.
The Fire Dept reported that the service arced bright blue on the ground for 20-30 minutes waiting for the utility to cut the lines. The transformers were a 3-Ø pole mounted bank less than 200 feet (of wire) away.
You can see the burn where the pipe and riser conductors laid on the ground. There is approximately 10 feet missing (it incinerated) The Fire fighters said that steel will relax when it’s temperature reaches near 1500F. I do not know what the available short circuit current was. I had to leave for vacation the day after the incident.
WOW! Curious about something here... Was the gas service bonded to the EGC? (Or formerly when the panel was actually in place?) This looks like a house, with a 3 phase service? Something you don't see here everyday... People that live here have someone watching over them!
The occupancy was a commercial motel. The fire department was extremely concerned that the entire area was in peril if the gas touched off. They blocked off a stat highway until the utility was cut, and maintained a considerable distance.
Show this to anyone who douts the power of electricity. Imagine being on the other side of the wall. It also reinforces the point about having proper distance between utilities. This could have been soo much worse if that gas meter was in a worser spot.
