In Section 1.1 the stated purpose of the NEC Manual of Style (MoS) is:

...It is intended to be used as a practical working tool to assist in making the NEC as clear, usable, and unambiguous as possible.
Personally I believe that that?is indeed the intent of the MoS. A good example of this, is the attempt to make exceptions ?positive text? and if exceptions are still necessary locating them such that it is clear where they apply.

Never the less, I?m fairly sure most of us agree the NEC still has a way to go ? if it were "clear, usable, and unambiguous" this would be a much smaller community. ;)

Over the years, I?ve developed some personal, informal rules on how the NEC should be interpreted such as, ?A sub-section must be interpreted in light of its primary section? or ?A section must be interpreted in light of the scope of its Article.? I?ve seen too many people jump on a single sentence ? even a phrase ? often unrelated to the subject and totally misconstrue the intent.

Has anyone seen a formal set of ?Rules of Interpretation?? In 35 years, designing projects in over 100 distinct jurisdictions nationwide (and over 25 international ones) I?ve never seen one.
 
Re: Rules of Interpretation

The term "rules of interpretation" sounds and awful lot like "rules of opinion". How do you make rules for that?

Intent tied with determined hazards should also be the focus of interpretation. In my opinion, a single sentence can change the entire reasoning and purpose of a section.
 
Re: Rules of Interpretation

I agree see:

110.1 Scope.
This article covers general requirements for the examination and approval, installation and use, access to and spaces about electrical conductors and equipment, and tunnel installations.
110.3 Examination, Identification, Installation, and Use of Equipment.

(A) Examination. In judging equipment, considerations such as the following shall be evaluated: .............. and

(8)Other factors that contribute to the practical safeguarding of persons using or likely to come in contact with the equipment.


This can be interpreted anyway you want, eh!
