Progressive Industries Electrical Management System

Today I purchased a different adapter and will see if this fixes the open ground problem. Progressive Industries has told me that their system does not care or know the difference between 15, 30 or 50 amp services. So they are also suggesting that the adapter is faulty.

Well today I had the opportunity to try my new adapter and all works good. So this being said...I have 3 "puck" type adapters and every one of them showed the same, open ground, fault. Guess I have learned something today.
