The device only needs to match the breaker rating if there is only one place to plug into. A regular duplex receptacle counts as two places and are allowed to be installed on 20 amp circuits.

Its possible that the OP has a surge power strip plugged into those GFCI-protected outlets.

Surge power strips will shunt the minor surges to ground, thus creating mini ground-faults. A GFCI outlet with class A protection will interpret this as a fault sufficient enough to trip out.

Try removing the surge power strip(s) and see if your nuisance tripping continues....

I didn’t read each post thoroughly, but the mention of ‘cramming’ GFI’s into small metal boxes and having random trips makes me think that one or more of them may have their ground wire(s) touching the neutral terminal(s) (maybe intermittently). Under load, a short between neutral and ground will trip a GFCI (and not the breaker), as not all the current will go through the neutral, some will go through the ground wire(s).

Just a thought - after reading all of the posts and figuring that some if not all are possible, I wanted to recommend wrapping electrical tape around the outlet before placing into those METAL boxes. Cheap, easy, and as you can see - would rule out some of the possible causes mentioned.

Power strips by themselves are fine. It's those that have built-in surge protection that can cause nuisance tripping of GFCI devices.

The conflict here is the GFCI units are for people protection, while the surge units are for equipment protection.

And sometimes, you can't have both
