Wonder how far it would have spread otherwise? Assuming 3.5 kVA/foot and a
50A arc, that woulda been over 7000 ft. Too bad the breaker popped. Of
course I noticed the green glow of burning copper in the switch electrodes.
I guess it might have popped anyway once it destroyed the reactor (or
something else) with such an arc and directly shorted to ground somewhere
long before a mile was reached.
