The NEC has been in existence for over one hundred years and uses technical language, not layman's terms. This eliminates confusion.
It is not easy to read and not the easiest to understand unless you already have a firm grasp on the fundamentals of electricity and electrical work. The NEC is not a DIY manual. There are lots of books out there that are sold soley for the purpose of explaining parts of the NEC.
Almost every single chapter and section of the book has to do with residential in one way or another. You can probabl skep the 500 series section and some of the 700 section but you will find information that you need in every single part.
Here is an example:
A simple item like bonding or grounding the main panel is covered by multiple sections such as 250.50, 250.50(A), 250.52(A)(1), 250.66, 250.53, 250.53(A) & (D)(2), (E)(G)(F) and even more depending on other sections.
