LK,
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.
