I know the panel your are talking about and have used them before without any problems. I don't know why they would have changed the requirements to no longer permit this type of panel design since the meter is still isolated from the customer conductors. The only disadvantage to this type of design is that the meter needs to be removed to access the top section. I would try talking to someone else at the utility to make sure the first person that turned down this installation was not wrong. If they still refuse to accept it then your local Home Depot should pull this model from the shelves. You also could call Murray and see what they have to say. If they say that the panel DOES meet EUSERC requirements have them talk to the utility. GOOD LUCK!
