I was told they do protect downstream wiring. But they are also the same price as a breaker. So you might as well install a breaker and protect the whole circuit.FrunkSlammer said:So it protects upstream wiring?? How far upstream does it protect? Damn that could be awesome or horrible.
We put then in on a remodel a while ago. The sub panel was full of twins with no room for full size breakers. We didn't pull new home runs, just reworked existing. I tried to change the sub to one with more space, but got shot down by the GC and HO. The AHJ said to use the AFCI outlets, they work great till you plug in a vacuum.
Yes, that requirement is for new circuits only. A replacement receptacle or extension of an existing branch circuit doesn't have that requirement.I heard a rumor that you must feed an AFCI receptacle with either emt or mc cable in order for it to replace an arc fault breaker... Anyone else?
