I’m gonna say that gfci might be bad. I still don’t see how you can pull 15 amps from that small aquarium unless your heater is bad causing the gfci to trip. That’s the only intermittent unit correct ?
I found the culprit this morning. I have two heater from the original setup. As soon as I plugged in the "culprit", the AFCI tripped. It's an older finnex heater.
Purchase date was 2018!
I also sent an image of my breaker box to an Electrician. He advised on a few steps, and if it tripped again he would replace the AFCI.
I have to edit GFCI > AFCI, lol, now I know where I got the GFCI from.
