I have a duplex that my company wired. One unit that has its own meter has been tested and all circuits including the arc faults are working without issues. On the other unit, there are a total of 6 arc fault breakers (3 on subpanel A and 3 on subpanel B) and all of them are tripping. At best, it might power one light, but any load above that trips them. One of them was even tripping when I turned on the bath exhaust fan that's on a different circuit. We exchanged all the arc faults for regular breakers and none of them trip. Any ideas where my issue may be? The main disconnect feeds a 200 amp panel downstairs. The 100 amp subpanel upstairs is fed from the downstairs 200 amp subpanel. Is it likely an issue with a compromise in the main feeder, riser or even the triplex?
Homeline Square D panels. Arc Faults are all 15 amp general lighting circuits.
Thanks for any help.
