If you are curious, the national electric code is freely available on the website, albeit in a slow and page by page online viewer. Equipment manufacturers will also often give installation manuals that can be reviewed and combined with the NEC for a decent understanding.
Ugly’s and other companies do pretty affordable handbooks or small books that summarize electrical info/calculations, or wiring methods from the code.
But overall, national code standards are written in blood, and the NEC is made through the NFPA, National Fire Protection Agency. Their intentions are to prevent fires, and that guiding principle leads to code changes.
