This is a new requirement for the manufacturing of GFCI breakers and receptacles. UL has upped the bar for these devices requiring them to self test. If one of these devices detect a leakage of current they trip and have to be hand reset. The tripping of one of these devices may signal a wiring problem in your home. So just resetting may not solve the problem. Below are a few links to these new products, one of these links is for a receptacle that will not turn on if wired improperly. The UL requirement for these devices went into effect in June of this year (2015). The inventory of old type GFCI protection will be allowed to be sold but all new devices will be manufactured using the new standard. If you can’t get the links below to work just put “self test GFCI products” in your search bar.
