Answer:

Hey Micheal thanks for your question. Flexible cords can be used based on the conditions in 400.10 and 400.12. One permitted use is pendants in 400.10(A)((1). Although specific wording regarding how vertical the pendant must be is not provided flexible cords generally cannot be attached to building surfaces as stated in 400.12(4). The AHJ will need to make the final determination how much of an angle they will allow before it does not seem like a pendant.
