I have been involved in the NEC process on a local and a national basis since the 1978 Code cycle. I started as a member of the City of Phoenix NEC Review Board that evaluated the 1978 Code for possible local amendments, usually based on the elevated temperature issues found in the desert during the summer. This review process involved many hours and days of studying the Code to determine whether the local conditions required changes and, if so, what the changes would be and how the local code could be changed using proper Code language. This in-depth study was incredibly challenging for me, but it provided a better understanding of the local and national electrical issues. Starting in the 1990 edition of the NEC, I was on Code-Making Panel (CMP) 20, then went to work for NFPA for nine years doing the 1993,1996 and 1999 NEC, and then spent the next 20 years on CMPs 1, 3,4,7 and 13, and the NEC Correlating Committee from 2005 through 2017.
