010 Luminaires in specific locations.

1. (1) All luminaires within an enclosed shower area or within five feet of the waterline of a bathtub must be enclosed, unless specifically listed for such use; these luminaires, with exposed metal parts that are grounded, must be ground fault circuit interrupter protected.

   042 Luminaires with exposed conductive surfaces.

2. (2) Replacement luminaires that are directly wired or attached to boxes supplied by wiring methods that do not provide a ready means for grounding and that have exposed conductive surfaces will be permitted only where the luminaires are provided with ground-fault circuit-interrupter protection and marked "no equipment ground."

   056 Protection of conductors and insulation.

3. (3) Requirements for stranded conductors in NEC 410.56(E) do not apply to branch-circuit conductors.

   062 Flexible cord connection of electric discharge luminaires.

4. (4) A ground-type attachment plug cap and receptacle connection at the source junction box is not required when the flexible cord complies with NEC 410.62 and the following:

   1. (a) Connection to a source junction box must utilize an approved cable connector or clamp;
   2. (b) The maximum length of the cord for a suspended pendant drop from a permanently installed junction box to a suitable tension take-up device above the pendant luminaire must not exceed six feet;
   3. (c) The flexible cord must be supported at each end with an approved cord grip or strain relief connector fitting/device that will eliminate all stress on the conductor connections;
   4. (d) The flexible cord must be a minimum #14 AWG copper;
   5. (e) The flexible cord ampacity must be determined in NEC Table 400.5(A) column A;
   6. (f) The flexible cord must be hard or extra hard usage; and
   7. (g) A vertical flexible cord supplying electric discharge luminaires must be secured to the luminaire support as per NEC 334.30(A).
