GFCI receptacle with a GFCI breaker??

[NewGuy111]

I know its redundant, but for the sake of argument would a gfci receptacle still work on a gfci breaker? Or would they both just trip instantly?

will work

Commonly done but usually accidentally. I agree it will work. AFCI and GFCI will also work together and most afci's has some gfci built in-

With GFCIs in series, the only issue is that either one of the devices or both of the devices will trip on a ground fault. Not a real issue, except finding both devices to reset them.

Who cares if one works or not if the other works?

One of the two devices will work. That's all that anybody should care about.

Well, if it turns out to be a GFCI receptacle behind a full height bookcase filled with books, it does matter which one tripped.

Same would be true if the breaker is behind the bookcase:happyyes:

So far my experience is that the gfi closest to the fault has tripped before the other.

I usually find the farthest one tripped, thought it had to do with "leakage" in longer run of cable

I respectively disagree !......Cost should always be a prudent consideration for any project ! :thumbsup:

I didn't realize we were debating whether or not you "should" use both. I thought we were talking about a situation where both were being used for some reason or another.

Also I never know how to take that "thumbs up" emoji at the end of posts that aren't congratulating me for being right.

That is correct, the "ground fault protection" that is built in is essentially the same thing as GFCI but does not meet Class A GFCI trip levels. Class A trip level is 4-6 mA where the GFP in an AFCI breaker is 30 mA or even more.


Many also believe this GFP alone provides us with more reliable protection from arcing faults then the rest of the arc detection components.
