You're right. That's a pretty standard setup. A member of my local was killed when the line he was working on automatically re-closed, twice. But the faults causing the circuits to open in the first place most often occur when power lines come down and ground out or when transformers come down off the poles and short out between the phases or just fail from the shorting lines. Strong winds can cause shorts when the lines (which are mostly uninsulated) whip into one another.
We're hoping for the best for everyone affected by this storm. Keep us informed as to how you're doing. Best wishes to you all.
