Energize said:Since some here believe article 90 is not enforceable, this must mean they do not believe there is any enforceable purpose 90.1 or intention 90.1( C ) or scope of what is covered or not covered 90.2.
This is where there is a misunderstanding of what is being discussed.
Article 90 is an introduction to the NEC, nothing more nothing less.
It is only explanatory of how the code is laid out, what is and is not covered, how it is to be enforced, etc..., there is no "directive" as far as a code requirement that could be cited any where in the article, the code requirements are elsewhere in other articles and sections.
As fas it being a pertainent part of the code, yes it is but, it is not commanding any requirements.
