In Article 210.12 it appears to indicate three different types of arc-fault circuit interrupters: a) listed combination-type, b) listed branch/feeder-type, and c) a listed supplemental-type. What are the differences between these three AFCI devices? From the code it appears if the listed combination-type is used the conductor length limitations cited for the other combinations does not applied. Is there a preferred configuration of AFCIs to use? Is one combination safer than the others? Is configuration more economical?
