I have 3 GFCI on a 15 amp circuit. They constantly trip. Plugging in a toaster will trip them. Many times they trip with nothing plugged into them. I replaced the breaker with another 15 amp. I replaced again with a 20 amp. They are visually wired correctly. My "plug-in" checker says all 6 outlets are wired correctly.
What am I missing ??
Should I remove two and leave only the primary GFCI ??
Thank you

Disconnect them 1 at a time. Check the circuit and if it trips reconnect the first one and go the the 2nd and so on.
It's possible that one for the GFI's is defective.
The process of elimation.
Also turn of the breaker at the panel, unplug everything on the circuit and check with an ohm meter. Check across the hot and neutral and also check both sides to ground.
I have faulty GFIs on two of my circuits right now. For some reason they keep tripping the GFI Breakers around the same times each day. Mostly in the evening between 6 and 6:30 PM and sometimes in the morning around 6 AM. It's strange and only began happening a couple of weeks ago. Then it would happen maybe once a week. Now it's happening every day. And yes, I checked every outlet and they all seem to be working correctly. I checked to see if any timers or clocks were going on or off - not the answer. I checked to see if anyone had used a nightlight - the kind that goes on at dark and off at daylight - not the answer. The two circuits are on two different ends of the house too. One's in the master bath/bedroom and there other is in the Guest bedroom/bath. They are each on separate GFI Breakers.
This morning is the first time I was in the den when I saw something suspicious with the lights happen. I was at the PC and the ceiling light above me dimmed and flickered. Immediately I heard my partner's CPAP machine alarm beeping because the power went out in the bedroom.
Oh, I just thought of something - In early November an Electrician added a circuit to the GFI when he added a line to power the pump to my newly installed pond. That's on it's own circuit breaker, and it's turned off for the winter, but he did still work with the GFI system. I wonder if he unintentionally did something. I'll be calling him up today.
I needed to install GFCI outlets in my kitchen and bathroom. When I spoke to an electrician I trusted, I was told you only need one GFCI on the first outlet of the series to protect the entire run. He told me that if you have more than one GFCI on the same breaker they will fight each other and just trip over and over. I dont really know enough to give a more technical explanation, and of course consult a trained professional, but this is what I was led to believe. Hopes this helps and didn't come too late.
