Curt, while it is true that the relatively small conductors of the coax, and the rest of the circuitry involved could of and DID lessen the current value here. This is why Breakers have AIC ratings - so they don't catastrophically explode like this. But I think it is pretty clear. Lightning is a shot in the dark - pun intended.

It seems likely that the young technician connected the rooftop end of the cable to a similar-appearing, but now obviously incorrect electrical cable. In any case, both technicians stated that the company-installed "system" of cables on the roof were "a real mess" and were unsafely stretched over and near an electrical box and associated cables.

RG-6Q and #2AL service drop conductors look very similar - until you connect them apparently. [Linked Image]

Anyway.... We disagree on that for now. I looked at the forum this is posted on earlier, and looking to see if they might be able to elaborate on 'What' he connected to.
