Are there any big downsides to Daisy chaining GFCI outlets? I understand that protection would be redundant. I have an outside outlet that's protected by an upstream GFCI that's located inside the house. I am replacing the outside outlet and am thinking of replacing it with a GFCI. My thinking is that when it trips I'll be able to reset it outside rather than inside. I understand that if the inside outlet trips I won't be able to use the outside one until the inside is reset.
That won't work
You're trying to manage sequence of breaker trip, for your convenience of resetting them, and that's tough to do generally.
Especially it isn't going to work with GFCI, because they don't work that way. When there's a ground fault, they all will trip by design. And then, you will have to fight to reset them.
I fail to understand the core problem that you are attempting to solve. They shouldn't be tripping at all. If you have a device that is tripping GFCI, fix it. It's broken.
If you want to make the two GFCIs independent, then connect the inside one by pigtails to the line. If the outside receptacle is not the terminal one, then connect it also by pigtails. Don't use the "load" connections which are usually sold taped over.
If I understand this correctly, this way each GFCI receptacle would only trip if there is a ground fault in something plugged into that receptacle.
It may not work the way you think it will
You could have any of:
- Outside outlet trips and inside outlet does not trip - which is what you want
- Inside outlet trips and outside outlet does not trip
- BOTH outlets trip
I don't think there is any safety problem with this configuration (Harper or one of the other experts can answer that) but I wouldn't count on it working as you expect.
