One of my local AHJ's says the 1972 NEC (if memory serves) was kept in his back pocket for over 10 years, before California adopted another code cycle some time in the 1980's.
Well, I started in the trade in CA in 1974 and we were being schooled in the 1971 NEC then. There never was a 1972 NEC, it jumped from 1971 to 1975 which was an exception to the three year cycle. I don't think that Title 24 - the CA Building Code - was created until the late '70s. Now we do go by the CA Electrical Code (CA Code of Regulations Title 24 Part 3) which is basically the NEC with some CA additions/changes, primarily in the administrative areas and also quite a bit in the healthcare sections.
If your still going after 46 years, maybe there is hope for me retiring at 70.
I'm still going but I'm going a bit slower these days. I sold off my main company to my son last year and kept my old EC License to continue to do consulting work, small projects, and help doing fill-in work where my son needs it from time to time. It has been a good run so far in an industry that has really evolved over the decades. When I was taking night classes at the beginning of my career I actually took a class in slide rule. Calculators were very costly back then and many of the old instructors were bucking the trend.
I'll be 65 in May, and I'm still doing it all.
My bosses dad was still doing it all at 75. If I can I still will be doing it too. Key part of the equation is he was doing it because he wanted to not because he had to.
I was born in 52, I quit working years ago because I wanted to.
