We never had the insulation separate from the plug, but several years ago, plugged into a pedestal in an RV park, and the EMS would not power up the rig. It said the ground was missing. The park manager sent over their electrician and he tore apart the pedestal and everything was intact. Before he got there, I even tried connecting the 50 amp cable to the pedestal with my 50 to 30 amp dogbone, and still no change. After the electrician put the pedestal back together, I pulled the 50 amp plug out of the dogbone adapter, and found the ground prong was stuck in the dogbone adapter and had broken inside the molded plug. A new plug fixed the problem. Those molded plugs are not the highest quality, so this might be a perfect opportunity to solve a problem before it occurs.
