Open-ground hazard

Why aren't phase failures discussed more often? Could it be? Neutral bus and conductors are more vulnerable? How would that be possible? Or the succinct question How Would That Be Permissible?

Just a guess here. When we hear of a neutral failure it's usually in the context of fired equipment from too high voltage. A phase failure never results in voltage being too high, drastically reducing the risk of fried equipment. It's more likely for somebody to post "The park power fried my equipment", rather than "The power wasn't right so we had to move to another space". And the subject of the thread, open ground, usually goes undetected until somebody feels a tingle from the RV body.
