Tripping breakers

[mai]

Had a call Friday night from a customer whose new house we wired 3 years ago. She said that all of the Eaton AFCI breakers and Dual function breakers in the panels tripped within a few seconds.
When I got there a little later I found them all tripped. None of the standard single pole or double pole breakers were tripped. I reset all of them and within 5 minutes they tripped again all within a few seconds. The flash code was six times which means self- test fail, defective breaker.
After resesting them again 5 minutes later all of the breakers on line 1 tripped at the same time.
In coming voltages checked out ok. Utility company said they weren't aware of any problems. This house is on its own transformer. Owner stated they haven't changed or added any new appliances. They also aren't aware of any lightning strikes recently.
Eaton is sending all new breakers to me.
Anyone else ever experienced this or have ideas of where to start troubleshooting?

Welcome to the forum.

Suspect the solar flares.

Been hearing this a lot, with the all the AFCI‘s in the panel, or all of them on one side, tripping. Seems to be atmospheric.

Glad the AFCI’s are saving us all from…..from….something?

Don’t discount the Solar Flare entirely. Seems like a lot of coincidences in the last few days.

I believe 100% it had to do with solar flairs. Talked to two farmers in the area who said while planting during that time that the auto steer in their tractors, which is GPS controlled was causing major problems. Now the weather service is predicting another event soon. Great!!

Yes, it was not coincidental. The issue made our area news

Look around the neighborhood for a Ham radio antenna on someone's roof. That's a known issue, discussed in here several times in the past. There is even a video on YouTube showing it.

It just hit me: "Tripping Breakers" to be sung to the tune of "Smiling Faces."

Maybe I should make up some new words for that song.

Another example of AFCI working when nothing is wrong and not working when devices burn up from backstabbing. Junk that was forced on us by overzealous authorities.

Eaton has SPD built in, but won't last forever. Whole house SPD is still needed with AFCI breakers.
This Solar maximum has been spitting serious flares & EM storms for several months, surprised those AFCI's lasted this long.
