This groovy “new-tech” NM-B seems to hint at a future plenum-rated cable. In the second link, mention is made of compressed stranding, but it’s not clear if 14-10 are solid or stranded. [I hate solid conductors but have rarely touched NM-B.]

[If I had to wire a house at gunpoint, I’d want FREP tray cable to do it, and regularly take the inspector out for a lot of drinking—but not before 1:30. Some work has to at least look like it’s progressing.]
