There is some evidence on-line that human body resistance can be estimated at somewhere around 1000Ω. The classic formula

P = GV²

in which G, the conductance, is 1/R, and V = 33kV, we get 1.089 MW into Mr. Copperman. Of course, that's assuming no line drop, and it's also assuming no increase in resistance over time due to the... ahem... loss of conductance that would occur as Mr. Copperman's bodily fluids ah... outgassed.

On the other hand, he may have been ingulfed by a huge arc, in which case the resistance would have been much lower, just a few ohms. In that circumstance, the power dissipated could have been much higher, many megawatts. It's hard to imagine how he could have been alive more than a few milliseconds though.

Dead? Looks alive to me.

I was a master electrician a long time ago, and be assured that most of the current did not travel through his body or there would be nothing more of him than tiny pieces of flesh.

More likely, he was using bolt cutters to cut the wire and the cutters caused a short to the electrical cabinet which caused the explosion.
