2017 NEC code question: So I’m installing low voltage 12vac luminaire to a deck post near a pool/spa/inground hot tub. It is located little over 5 feet away from the inside wall and up 8 feet heigh. Art. 411.5 (b) says no less than 10 feet from nearest edge of pool unless permitted by article 680. So when I go to 680.22 (b)(6) it talks about within 5 feet with low voltage Luminaires. But my measurements are outside of 5 feet and 8 feet high . So when I look at 680.22 (b) 4 it looks like it just has to be rigidly attached because I’m over 5 feet heigh? I just don’t know if that means low voltage luminaries also ? What part of 680.22 does my installation fall under? Thanks Steve



Hey Steve thanks for your question. The wording is not extremely clear but your installation is covered by 680.22(B)(6). Luminaires, lighting outlets and ceiling-suspended (paddle) fans, such as those on 120-volt circuits, between 5 and 10 feet horizontally from the inside walls, must have GFCI protection - unless they are at least 5 feet above the maximum water level and rigidly attached as stated in 680.22(B)(4). Listed low voltage luminaires that do not require grounding, and that don't exceed the low-voltage contact limit (as defined in 680.2) and are supplied by listed power supplies that are identified for swimming pool and spa use [680.23(A)(2)] are allowed within 5 from the inside walls of the pool as stated in 680.22(B)(6). If they are allowed inside the 5 ft dimension it makes sense, they would also be allowed beyond that dimension but that wording is missing. Make sure you also follow the instructions for the equipment.
