And how would you classify them for NEC purposes as regarding distance a GFI receptacle must be from them? At one end of the spectrum, as I see it, is a swimming pool. At the other end of the spectrum is a bucket of water I use to wash mycar. These troughs have a large volume, like a swimming pool or fountain, but are portable, like a bucket or cement mixing trough, not fixed like a swimming pool, spa or fountain. Unlike a swimming pool or spa, they are not made, used or intended for human occupancy of any kind. What would you call them? How would you classify them? I could see arguing this a couple of different ways. I put this up here because it seems like these occupy a gray area of the NEC. They don't fit a "definition" per-se- they're not pools, spas, fountains or man made bodies of water, in their strictest sense, which leads me to defining them by "what they are used for" which seems like an even murkier and subjective discussion. What say you?
