Some manufacturers make them. What brand do you needDoes anyone make 2 pole AFCI breakers that can be used on MWBCs?
They do but depending on what brand it is. and be aware they are not cheap either.Does anyone make 2 pole AFCI breakers that can be used on MWBCs?
So the only good brand is the one you use-- I get it..:no:as far as I know, cutler hammer and ge. both junk brands.
That is about right-- It is about the cost of 2 sp afci breakersI know that Siemens has them as I have used the 20a before. As for being pricey, I think it was actually cheaper to buy one of them vs two single pole AFCI breakers.
They aren't in the QO catalog.Thanks for the info. Does Square D make one for QO or Homeline?
The last time I asked they said no but that was a few years ago.Thanks for the info. Does Square D make one for QO or Homeline?
Yes, it is a dp breakerIf the MWBC has an arc fault on one of the circuits, will the 2-pole breaker kill both circuits?
Well, I would not do that in my house then (MWBC). I'd hate to lose 2 ckts if I had a small arc fault.Yes, it is a dp breaker
I would never wire it that way either but in some cases you may be stuck with an existing multiwire branch circuit. Now with the afci receptacles the dp afci may not be as necessary as most contractors don't pull multiwire branch circuit in homes any more.Well, I would not do that in my house then (MWBC).
