I don?t want to shock you but the NEC is not the Holy Grail. No it is just one of NFPA?s hundreds of reference guides that inspectors and engineers use to insure that electrical work is installed in a safe manner.
NEC 90.4 states that the ?authority having jurisdiction [AHJ] for enforcement? of the code has the responsibility for making interpretations. This is generally the ?inspector?. The NEC has some areas that are black and white but most of it is gray and needs interpreting.
NEC 100 states that the AHJ is the individual responsible for approving the installation.
There are three kinds of jobs that electricians work on. (1) Projects that require inspections by governmental bodies, then the inspector is the AHJ. (2) Projects that do not require city/state types of inspections but are designed by A/Es. Then the architect and/or engineer is the AHJ. (3) Projects that are done for friends or outside jurisdictions and are not designed by A/Es. Then the electrician is the AHJ. This may seem like the best kind of project but it hold the most liability for the electrician. You are 100% responsible for the project. While the other two types of projects share the responsibly with the electrician; this is better for the contractor if you go to court. The inspector is classified as an expert witness and has no vested interest in the project. His interpretation of the rules will not be altered by the lawyers, as will the electrician?s interpretations.
So when people in the forums ask questions and receive answers, be aware that just because an interpretation of a rule is allowed one place is no guarantee that is will be interpreted that way somewhere else. So going crying to an engineer because an inspector turns you down will not change any code enforcement issues. You are lucky if five inspectors in the same city interprets the rules the same.
