Did You Know #4 - National Electrical Code (NFPA 70)
Code Arrangment    (08-23-2008)

From: 2008 National Electrical Code® (NFPA 70®)

An essential code "requirement" is presented in Article 90 of the National Electrical Code (NEC) - 2008 Edition (...and earlier editions as well).
It states:

90.3 Code Arrangement   This Code is divided into the introduction and nine chapters, as shown in Figure 90.3. Chapters 1, 2, 3, and 4 apply generally; Chapters 5, 6 and 7 apply to special occupancies, special equipment, or other special conditions. These latter chapters supplement or modify the general rules. Chapters 1 through 4 apply except as amended by Chapters 5, 6, and 7 for the particular conditions. [Emphasis added]

Part of Figure 90.3

I mention this "requirement" because I've noticed that an inspector will occasionally attempt to force a general contractor to change a condition that is perfectly safe and legal. For example - an overhead fluorescent light fixture is equipped with a 6 foot section of flexible metal conduit ("flex") connecting the hanging fixture to a junction box on the ceiling. Article 620.21 (Wiring Methods) permits limited use of "flex" in the machine room - but this article is concerned with elevator and related equipment only. Light fixture whips are not governed by Article 620.21. Our concerns with light fixtures are limited to mostly required illumination, fixture location, light switch location, etc.

Of course, if you see something like this you gotta squawk!
"It's just a short piece of garden hose...won't that work?"

Incidentally...this is why every box should have a cover.
This "situation" was found behind a stove.
I suppose the fork was used to see if the job was done!
