Hmmm...is there a published list of what products are exempt? Bob Axtell wrote: You need to be aware that some products are completely exempt from FCC Part 15 and some are exempt from UL testing as well. FCC exemptions include power company controls and instruments, some medical devices, and many industrial items, from robots, and mining equipment and including oil-well tools. The products I am making for power company testing are all exempt. --------------------------------- Building a website is a piece of cake. Yahoo!
