I have a client who wants an indoor garden, including outdoor LV landscaping lights near a custom-built tub. I am having trouble finding a reference. I plan on running 14-2 NM from the transformer to a NM junction box on the front wall of the tub enclosure (facing away from the tub) and outdoor cable from the junction box to the lights. Does the junction box need to be water-resistant, water-tite, or can a standard NM box be used?
