I was looking into Art 422.52 (drinking fountains protected by GFCI) and noticed in the IAEI Analyisis book that they say " Action by CMP-17 clearly indicates that this GFCI protection requirement does not apply to bottled water coolers, but only to those electrical drinking fountains that provide a refrigeration feature as part of the appliance."
A couple things
1. I could not find a definition for an electric drinking fountain in the 2008 Code.
2. None of what seems to be an exception in the Analysis book appears to have made it into the 08 code book.
3. Most of the bottled water coolers I have come across do have a refrigeration feature. The water gets cold some how so does this need GFCI protection?
4. What about water filtration water coolers?
