In raceways, which conductors must be stranded?

Explanation:
In a raceway, you have to pull conductors through a confined path with bends and fittings. Larger conductors are much stiffer, making them hard to pull and more likely to be damaged if forced around bends. Stranded conductors are far more flexible, so they can negotiate bends without kinking and with less stress on the insulation. For that reason, conductors 8 AWG and larger must be stranded in raceways to ensure easier installation and long-term reliability. Smaller conductors can be solid because their stiffness isn’t as much of a pulling issue and the code allows it in these cases.
