Answer to Question 1

Power wire is too small or poor connections at either end of the power wire.

Answer to Question 2

Even though enclosed cases reduce the total refrigeration load, they have additional energy requirements as compared to open cases. Anti-sweat heaters located in the glass doors require a substantial amount of energy. Enclosed cases also require more lighting as compared to open cases. Because of this there is very little total efficiency advantage between enclosed and open cases.
