Electrical Systems Based on the 2017 NEC®

Just as represented.

The book was exactly like it was advertised. Quick delivery as well.

This textbook does very little to elaborate on the actual 2017 NEC book. It adds some diagrams and illustrations but does a very poor job of much more than nearly copying the content of the code book. Much of the content will span several pages without being broken into topics. Reading this is like reading the code book. It is no more useful than the actual code book in my opinion.
