I see a real application for something like this in areas that require an outlet by code, but are not likely to get alot of use. So instead of mounting a standard duplex in the hallway - you can pop one of these interesting looking outlets.
FYI in the US you can manufacture and sell anything without UL listing or any kind of code compliance - laws are tougher elsewhere: in Canada, eg. in order to manufacture and sell electronic goods you must meet standards as well as meeting installation requirements.
Bottom line in the US, just cause you can buy it, DOES NOT mean it's LEGAL OR SAFE.
Joke-heavily-implied-by-the-next-statement: that's what inspections are for. GET IT? Sorry. It's midnight and I've got a drink or two in me! Whoo HOOO Happy New Year everyone!
If I could only remember to THINK about what I was doing before I did it.
