Pat and Pierre,
Nice to see that you guys, (like me) can laugh about things like that happening, during your time as an Electrician.
Here's another, from my files:
Within 2 weeks of starting with the PoCo here, I was required to re-string some 11kV
Lines.
That wasn't a problem, but I reckon that the flash that came from the crossed wires that happened after I did the whole thing un-supervised, did!.
Darn!
