If you really want to protect the receptacle, chuck that bubble cover when it breaks and put a set of snap covers on it. I think the NFPA took a giant step backward when they removed the "unattended" language from this rule. Bubble make sense if you are plugging in a landscape timer or something else that will stay there but the convenience outlets around the house are darned inconvenient when there is a huge wasp nest in there. (dirt daubbers laying eggs in the ground pin hole etc) They also do a lousy job of keeping driving rain out. That is probably why they had to come out with the WR receptacle.
