Section 680.27 (C) (3) (2002 NEC) says that radient heat in the pool deck is not allowed. What do you think about allowing the radient heat in the floor of a pool cabana, that is only 20 feet away from the pool? If the NEC doesn't want radient heat around the pool, should it be allowed in the cabana? Isn't there still going to be people walking around barefoot? I am just pondering a question here. I have someone asking about it.
At the end of the first sentence of 680.27(C) it is made clear that this section covers the area within 20 feet from the inside edge of the pool. Keep the radiant heating cables embedded in the deck at least 20 feet away, and you will be OK.
Personally I don't see this as any more dangerous than a radiant heater in the floor of the bathroom but it should be > 20' from the pool just to make 680 happy. These are GFCI ??? ... so a failure will end up being a tripped breaker.
Here is another question that came up. Has anyone seen a pool light at the bottom of the deep end? I know that it is not allowed under 2005 NEC but since we are still under 2002 NEC, I would have to let it slide, right?
I asked the EC about this one. He said the HO was adament about keeping that light fixture. They know that they will have to hire a diver everytime the have to change the bulb. I at least got them to change the bulb from 120 volt down to a 12 volt type. I told the EC that I know (and he does now) that the 2005 NEC won't allow it, but the 2002 NEC was quiet on the subject.
Here is another thought. I was called out to help settle a dispute between an EC and the AHJ. The EC thought that the AHJ was picking on him. I cover for this AHJ when he is sick or goes on vaction, so the town knows me as well as the AHJ. The code says that when you feed a sub panel, then feed a pool the feeder must be in pipe all the way back to the main service. The Exception says a cable is allowed for an existing panel and feeder. What is to stop someone from installing a sub panel with a feeder in cable, getting an inspection, then adding a pool off of that panel?
