Sorry Bob, the story was not fabricated nor imbelished. I was a project engineer at UL Santa Clara at the time that the guy was electrocuted in his swimming pool due to the lens of the 12 volt pool light fixture breaking, and Harry Kavanaugh (now retired) and Wally Wedekind (retired eons ago) had the job of formulating requirements that would prevent a recurrance. Later I wrote the standard on swimming pool transformers, the type which would provide the required isolation. I mention writing that standard as an aside because I know of no other instance where the first draft of a proposed standard was written by single individual. Usually it is a group effort. The Santa Clara office was a small group back then, only about 12 engineers when I started. Come to think of it, that probably makes me older than dirt, but what the heck. Gabriel HNS
