I have a home that is totaly wired in EMT, are arc faults required?
Which is moot because they dont exist. Or do they?Yes. Exception #1 lets you run from the branch circuit OCPD to the first outlet in EMT without having that portion of the branch circuit AFCI protected, however you have to have AFCI protection for the the first outlet and the remainder of the circuit. This exception was written with the possibility of a feed through AFCI receptacle device.
There is a listing standard for them and at least one has been submitted to UL for testing.Which is moot because they dont exist. Or do they?
I can see protecting receptacles because of what gets pluged in to them but with this wiring system, which is more of a commercial than dwelling method, what's the purpose in protecting lighting circuits
