Remodel on a home with new wiring. Pretty much the whole house. Installed AFCIs. Owner calls with age old problem of vacum tripping the AFCI. I explain probably not much we can do and easiest is to plug into kitchen or bath circuit. Yup, he says he just plugged into a different bedroom and things worked fine. Knowing the guys AFCI'd to the 2011, that changes things. My help was on the way to add one last AFCI so the checked it out. Changing AFCIs on that circuit did no good. Only that circuit tripped.
He did not have a megger with him but did have good meter and checked each recept for accidental grounds by removing them from the box and checking again.
Small experiment of adding a 25' length of 14/2g romex at the breaker end of the circuit stopped the tripping. When he left he had extended the hot wire only by looping about 6' of thhn in the panel. Couple times around I would guess. No more trips
