Bill:
If it's a metal cover, how is it grounded???
I would ask the electrician to install a plastic cover (they are available), and inquire as to how he grounded it.
If it was not grounded, I would post a red sticker. (Based on this being a new install)
If it's existing, there isn't much that can be done.
I still believe the mfg intends that the cover be oriented correctly to prevent water entry. The gasket is held tight by the spring tension, but the gasket and spring do deteriorate over time.
