The NFPA Terra View format should be called Terribly Hard to View. It sucks.

I agree...this new system is very much not user friendly.

looks like a AFCI receptacle installed at the first outlet using Romex still needs a listed pair breaker.

But the AFCI receptacle with a BRANCH / FEEDER AFCI breaker on an NM branch circuit has no restrictions.
Also, note that Garages, Bathrooms, Unfinished Areas, Mechanical Areas / Rooms, Exterior Wiring and Dwelling Outbuildings do not require AFCI. . . that is, the blanket "all shall be AFCI protected" was dropped and the list of rooms / areas was restored to 210.12(A)

Not only is the no afci supplementary afci setup as of now the manufacturers have given up trying to pursue this. IMO, this product would not have gotten off the ground simply because the cost would be high since there would be 2 units.
According to Mark Ode the idea of the 2 units was that it would protect against series fault better than a standard breaker or receptacle.

The rules for branch circuit and feeder wiring methods to pool equipment has changed...

Is this a good thing. Does using a Branch feeder AFCI and a OBC work better?

In reading the revised 2017 wiring method rules in 680.21, 680.23 and 680.25, in dry noncorrosive locations wiring methods in chapter 3 that do NOT contain a equipment grounding conductor can be used now...such as type AC cable, type MC cable without a separate equipment grounding conductor, metallic raceways without an EGC, surface metal raceways and other raceways listed for grounding. Also no more requirement for a feeder equipment grounding conductor (if used) to go to "service equipment".
I don't agree with this change. If the equipment grounding connection is compromised at the circuit origination, this would introduce shock hazards IMO. Maybe a NITMAM is needed.

In non dwelling areas stated in 210.8 a gfci will be required for all receptacles rated 150v to ground, 50 ams or less, and 3 phase receptacles rated 150v to ground or less, 100 amps or less

Well, the Code Making Panels say it is Code, so it "must be" :angel: good.
Your question will fuel the smudge pots here for a nice long thread, however.

Huh, what? Do they even make a 3Ø GFCI Receptacle?

Not that I know of but they do make three phase GFCI breakers.
No surprisingly, that's worded strangely.. (B)(1) appears to say "all" but then they go on to list specific areas,

I think it was through 480 volts in the PI.

I'm interested in seeing the language they use for saying that, but don't have a login. Is it still the language they had in 2014?

I'm glad the AFCI rules were rolled back from the original proposal.
