I assume you mean the "grounding" connection (the egc going back to the service disconnect in a 4 wire feeder) but if you have a 3 wire feeder that becomes a lot worse than in a 4 wire feeder because it is an open neutral condition along with all of the issues of a lost EGC added on. I suppose the lesson is make sure you don't have a fault in the neutral or the grounding conductor. It is not going to end well.
