....Most of the discussion I have found on this subject is somewhat "un-official" quoting the Consumer Product Safety Administration ( which a law suit found had no jurisdiction in the matter), a New York association of home inspectors, or one possible "expert" who did a study years ago. Some think all of these may have had their own agendas and might not be reliable. Even the Underwriter's Labs have been called into question for listing the Ideal purple wire nuts which others say were not tested under real use conditions. If this is really a problem why has it never been addressed by the NEC which seems to be the authority on everything else electrical.
Does anyone have any good current guidance on this subject? Sorry for the long question, just trying to figure what to do.
