Retired after 50 enjoyable years as a sparky. Yes back in the 1970's was told the NEC only had about 250,000 words and was easier. Probably double that in the 2023 NEC. Frustrating that even with maybe a halve millon words the NEC still does not cover everything. I would strongly recommend that you join & participate in local organizations such as the IAEI, independent electrical contractors or others. I paid my own way to my local 8 yearly IAEI meetings and learned things at each & every meeting. Found the vast majority of AHJ , L & I electrical units and inspectors open to answering your questions. Know for sure that inspectors would rather answer your questions so you can pass an inspection on first visit. Even though I'm retired I still look at the most visited electrical site in the world namely very talented Mike Holt for 7 days a week daily free graphic & code question along with Charlie Trouts great vide question if the day thru NICCA. Please don't give up , keep up with all the codes , work safe, maintain your life line = PPE & always use LOTTO.
