Posted here since it is more likely to be seen then in the shops section. Moderaters feel free to move it.
I got a physical letter in the mail yesterday from Schneider Electric, owner of Square D. Possible overheating and fire hazard.
QO plug on neutral load center have an issue from Febuary 2020 - January 2022. They will send a tech out to fix it for free.
My reading is it seems a bonding screw connecting the neutral buss to the special plug on neutral setup could be loose. I will just check mine with a screw driver.
To be honest I am not sure if mine has the special plug on neutral or not. My breakers are older and do not use the neutral bar, if any.
I think the plug on neutral is only used by GFCI and arc fault breakers
