You only have to bond if using copper piping. Why would you energize a motor by bonding it (taking it back to the sevice) if using plastic piping? This is the position our state has taken after I asked M. Holte for clarification at one of his 2005 classes.
You guys in Fla. don't even have basements! LOL You just have to worry about keeping your roof on incase you get those pesky hurricanes. Lets hope for a quiter season this year.
I just had an inspector ask to meet at the site, he wanted to see the manufactures sticker for max load, well there is no sticker on the tub, and we attached all the manufacture info with the permit application, so now we have to send a man, to open up the tub, only to see there is no sticker, Spa manufactures, should be required to have load information on every spa.
I agree that the manufactures should be responible enough to put stickers on all of their equipment. I use to fight with EC's about the AL lug on pool heaters. They always said that is was UL approved from the factory. I called Haywood here in NJ who manufactures pool heaters and I asked them why there is an AL lug on the pool. The pool rep told me that it was tested and UL approved. I asked him where it said it the NEC that AL was acceptable for pool bonding. After a pause on the phone, he said that he would have to call me back. It has been 5 years now and he still hasn't called. however I am now seeing pool heaters with CU bonding lugs.
regarding 3-prong caps on DI spa units....I had a discussion about 680.74 with UL not too long ago and UL mentioned that some manufacturers are still putting the 3-prong plug on DI units...the grounding prong is not connected to anything however and thus does not create a problem with the DI properties.
