The size of the NEC is both astounding and intimidating. However it appears that a good portion of the code is concerned with installation and manufacturing requirements of which the typical power engineer would have little interest.

What guidelines or advice would you give to a qualified engineer who is trying to learn the code's requirements? Is there obvious spots to focus on? What advice would you give to an engineer who would be largely motivated by the following roles:

1) design and specification of power systems for construction

2) inspection and supervision of electrical power systems installation for construction
 
If you are talking about transmission and distribution, get away from the NEC and dive into the NESC. Once you have a good grasp of that, come back to the NEC and start with the places where these two intersect, like at service installations.

Otherwise, what Pierre said. The rest will draw you in as you go.
 
I agree, chapters 1-4. Start at the begining and read through Chapters 1, 2, 3, and 4. You can probably skip some of the details on wiring methods, junction box sizing, etc.

Highlights might include definitions, 110, chapter 2 (including services, load calculations, grounding), 300, 310, and some of the Chapter 4 stuff including panelboards, switches & receptacles, etc.

Try not to memorize all the numbers and details. The NEC is largely a reference book. The important thing is to get a good feel for the major requirements, and figure out when you will need to look stuff up, and where to find it.

Scan the contents to find out what is in the last chapters (5-8) and refer to those as needed.
