AFCI breaker requirements

[jetlag]

I wanted to be sure what type of breakers are required now for residential construction . I know every 120 v outlet has to have AFCI protection now . I have already installed GFCI receptacles in the proper locations . I know they have breakers now with both AFCI and GFCI protection . Is it ok to leave the GFCI receptacles in place and use a regular AFCI breaker for those circuits ? I know also that the AFCI breakers now are CAFIC .So that is what I would use . I understand the C is for continuous in the same lead like between two conductors in a wire nut . What am I missing ? I thought AFCI breakers always did that before they added the C . If someone can advise me what breakers are required now , I will be grateful . thanks

Not "every" but most

Yes

I know also that the AFCI breakers now are CAFIC .So that is what I would use . I understand the C is for continuous in the same lead like between two conductors in a wire nut . What am I missing ?

The "original" AFCI protected against parallel arcing, the "c" or combination are for parallel & series, a second generation

"DF" or dual function AFCI breakers will have both GFCI and AFCI functions. Probably cheaper to use them instead of an AFCI and GFCI receptacles.

I really wouldn't worry about the combination "C" devices if I had to choose. Use the cheapest that satisfies code.

You must use "combination" AFCI (tha'ts about then only type you will find unless someone has oldddd stock) OR
dual function AFCI/GFCI
Exact requirements by circuit will depend on which Code cycle and local amendments.
