You know what they say, though. "Those that can, do. Those that can't, teach. Those that can't teach, become inspectors"
...or band directors, as the saying in my high school used to go!
My late old man was a broadcast engineer, and pulled thousands of miles of cable in his lifetime. He decided to build his own house in a small town. Of course, my old man did all of the electrical work by himself. When it came time for the electrical sign-off, the inspector figured "another DIY hack job" and booked the entire day to "educate" another wannabe electrician.
After checking the meter pan, the inspector went to the main panel in the basement. As you would expect from a broadcast engineer, the wires into the box were perfectly parallel, clearly marked, and looked like they were radius bent with a protractor where they fanned out straight into the panel. After spending a few minutes appreciating the workmanship that was worthy of an art museum, the inspector followed one branch circuit out to the end and signed off on the whole job in 15 minutes. (Remember, he booked a whole day for the inspection.) Long story short, the inspector asked my old man if he could delay closing the walls for a few days...so that he could bring every licensed electrical contractor in the town to see the workmanship that he expected from them from that day forward!
Ironically, the day before we closed to sell the house after my old man's passing, lightning struck the service mast. The bolt came down the mast, blew the meter apart, and went harmlessly into the oversized ground rod through the massive-overkill ground cable that my old man used. The panel and everything still plugged into power inside the house was not damaged in any way.
Anyway, just mentioning this because it's a case where those who can and those who became inspectors both wound up teaching.....
