Yea Electure, I did do some research and found the same thing .. I upgraded a customers service to a Square D homeline .. nice product, I had to lengthen the branch wires by 18" using a nema 3 enclosure, it looks clean and allowed me to terminate the older branches which would of been 6 to 12" too short .. come to find the specific city I worked in calls for AFCI if any of the older wiring was modified what so ever ..

Had I known this was going to be the outcome I would of installed an upgraded panel to conform to the only 2 manufactures that make a double pole AFCI .. Square D does not make 2 pole AFCI breakers because they know better it seems..

What bugs me is with this AFCI code now stating pretty much all breakers need this technology .. why are the other breakers made, they're outdated, right ?.. for commercial those breakers can be used, but how about the residential industry.

I'm just screwed, It will all work out, but what a hassle.

Being that this is inspected, I can put a different manufacturers breaker in this panel ..


Anyone claiming to know everything about Electrical, is wrong.
