Flexible Cords and Cables

400.8 Uses Not Permitted

This subsection was revised to read:

Unless specifically permitted in 400.7, flexible cords and cables cannot be used for the following:
(1) As a substitute for the fixed wiring of a structure
(2) Where run through holes in walls, structural ceilings, suspended ceilings, dropped ceilings, or floors
(3) Where run through doorways, windows, or similar openings
(4) Where attached to building surfaces
(5) Where concealed by walls, floors or ceilings, or located above suspended or dropped ceilings.
Figure 400–2
(6) Where installed in raceways, except as otherwise permitted in this Code

Intent: The change clarifies that flexible cords cannot be located above a suspended ceiling. However, wiring within a raised floor is permitted, because this space is not considered a concealed space.
