was on the roof of a restaraunt, replacing light bulbs, whan I came across this hazard. When the PoCo did their attachment, they failed to insulate their crimp connections. Of course, this did not prevent someone from mounting a light- atop the metal roof curb, less than a foot from 800 amps of heavenly transportation!.
That used to be the norm around here actually, and it is very common to find a service with bare split bolts just floating... Had a roofer walk back into the service of the house behind me and blow a hole in his shirt... Had an actual PoCo employee arc out a service a few doors up from me.... Scary isn't it
I'm not sure "mounting" is the right word to describe the light, either -- It looks like it's floating 1/2" above the wall. Interesting conduit work there: EMT into a 90 into a coupling into a nipple into a whatever. I hate seeing junk like that.
