I see a problem with that automatic self test..
(What is it you ask)
Per the article as I read it it means that from time to time the GFCI will, in a manner of speaking, press it's own TEST button, and trip. (one way it can work).
Imagine if that GFCI is feeding a CPAP and you, as a result, do not wake up in the morning.
Or if it's feeding a fridge and by the time you reset it all the food is spoiled.
Or.. Well several other disasters.
Do I trust the buttons? I trust them for the purpose they are designed.. but I play safe when working with Electricity or electric tools. I grew up BEFORE we had GFCI's to protect us.
