    Re: CQD answer published Friday, February 9, 2018 -2 Pole AFCI and 2 Pole GFCI CB's

    Thanks for the insight on the GFCI 2 pole breaker as for some reason I didn't think of that when running across multi-wire (12/3 with ground) homeruns in a residence.  Is there a 2 pole AFCI that would work on a 12/3 homerun to arc-fault protect those circuits if needed and then a combo AFCI/GFCI 2 pole breaker available as well?
