afci/gfci in residential

Well, hopefully we will see more of the 2/2 cable options showing up... I know some is available from Southwire, but not common.

On an aside, even though not required where I am...in a conduit encased in concrete, is the wire required to be burial type?

If the concrete is on or below grade, doesn't necessarily need to be rated for burial but needs a /W (for wet location) in the designation such as THW, THWN, or RHW. Above grade wall or slab is not a wet location without other factors involved to possibly make it wet.

Ok. So only the slab that will be a roof need be considered wet... but if the conduits go in the beams, rather than the slab, then it makes them no longer wet location, as far enough to mitigate the wicking then? With the deck roof plan... have extra beans designed in, so should be ok. Top deck is a two pour with plastic sheeting to try to stop water migration during rainy season.. so...

I would think most would call raceway in a roof slab a dry location. Roof will have moisture barriers as it is likely intended to keep everything below it protected from elements that may be above it. That don't mean you can't have temp conditions where it does get wet. See definitions of wet, damp and dry locations in art 100.
