luminaires above outdoor hot tub

[fisherelectric]

2011NEC
Client is installing a hot tub outdoors under a deck and wants LV lights installed above.
Art 680.22 gives a minimum of 12' above water line for luminaires {680.22(B)(1)} and allows luminaires between 5' and 10' horizontally from water line and less than 5' above the water line to be installed if on a GFI 680.22(B)(4)

411.4(B) says no LV luminaires within 10' of a hot tub unless otherwise allowed in Art 680.
Would 680.22(B)(4) allow LV luminaires in that area on a GFI? The code doesn't specify but I wonder if it's just a given that LV lights are prohibited since a GFI does no good.
Or am I missing something?

For 2011 I think you are right, new to 2014 is 68.22(B)(6):

Low-Voltage Luminaires.


Listed low-voltage luminaires not requiring grounding, not exceeding the low-voltage contact limit, and supplied by listed transformers or power supplies that comply with 680.23(A)(2) shall be permitted to be located less than 1.5 m (5 ft) from the inside walls of the pool

Thanks for the reply. And you are right...I found this after a search:


Listed low-voltage luminaires can now be installed within 5 ft. of the inside walls of a pool. In the 2011 NEC, lighting systems could not be installed closer than 10 ft. from the nearest edge of the water for pools, spas, or fountains. A new section has been added which permits low-voltage luminaires to be installed within 5 ft. of the pool under the following conditions:

The low-voltage luminaire is listed.
The low-voltage luminaire must be operated at or below the low-voltage contact limit.
The low-voltage luminaire must be supplied by transformers or power supplies that are listed for swimming pool and spa use. The transformer must be of the isolated winding type with an ungrounded secondary, but has a grounded metal barrier between the primary and secondary windings, or be of the double-insulated type.

The low-voltage contact limit is defined in 680.2 as basically 15 volts RMS for AC voltages and 30 volts continuous for DC.

Prior to this revision, some jurisdictions were permitting the installation of listed luminaires that complied with the low-voltage contact limit specified in 680.2 of the 2011 NEC even though the NEC did not specifically permit such installations. In the 2011 NEC, the general requirement in Section 411.4(B) required luminaires to be located at least 10 feet from the edge of pools but permitted closer proximity if permitted in Article 680. Until the 2014 NEC, closer proximity was not permitted in Article 680.

Now, provided low-voltage luminaires meet the conditions in 680.22(B)(6), the NEC permits luminaires to be installed less than 5 feet from the inside wall of pools, spas, and similar locations.
