My go-to brand makes double pole AFCIs and GFCIs but if they didn't make a double pole dual function breaker couldn't you just use a double pole AFCI and put GFCI receps in.
arc faults suck. after i passed inspection i pulled them all, resold them to someone else that needed them, and used good ol' $13 standard QO's. and made money in the end. I also had issues in the garage with brushed motors, oh wait, carbon that ARCS on the armature. yeah, guess how many Fin times i had to flip a reset switch. Out it went.
I'm running high wattage LED's, and the drivers make enough noise to annoy the breakers and kept tripping. I understand the point of arc faults, but the nuisance and annoyance they cause because of their built purpose, its just not something i want to deal with. Same with GFCI's, the installed one behind the fridge, and after my food spoiled twice, out it went, and a standard 20amp went in. the other one actually next to the sink and within reset-reach i left, thats good enough for the toaster.
Stupid.
