I installed several GFIC outlets this week and they were purchased at Menards (big box home improvement chain common here in the midwest). Spec grade 20 amp, in a tray marked Leviton but China made, have a valid UL sticker. 1 out of 3 are failing right out of the box, installed or on the bench. Interesting failure mode - they click about every 5 seconds but they don't fully trip and stay off. No down stream outlets. I have one clicking on my bench now I'm going to see how long it lasts. Then it will go in my "fails" box. If you're buying GFIC's might want to watch the quality.
I do a lot of safety training and many times when I bring up examples like this someone will say "it can't do that" or "that can't happen". Usually the guy with plenty of book but no experience. So I started a box of failed devices so I can show them what happens. Like 480V twist lock connector that shorted internally. What I could find of that one is in a baggie.
