It would be interesting to see the inside of that breaker panel in the last pic, to see how many tripped or if there was more "fine workmanship" in it too.
I'll bet that SER (SEU? SBC? BVD? RSVP?) cable put on quite a lightshow!!
Only a small percentage of EEs are schooled in power and even less regarding code. Unfortunately the majority makes the minority look bad.
My experience is electricians follow code and EEs write it. Scary huh??? Look at the titles at NFPA that work on the code. Lots of EEs in there....keeping everyone safe. Careful who you pick on....
