The NFPA is a publishing house - nothing more - and sells all manner of books they call 'codes.' The NEC is only one of these codes.
Even so, there are many codes that have no connection with the NFPA at all.
For example, while the NFPA does discuss bugseye placement in their 'life safety code,' it is the non-NFPA "Building Code" (IBC/UBC) that is actually adopted and enforced. The entire 'egress lighting' issue originates in the ICC "building code."
Ditto for the use of putty pads; it's a 'building code' issue.
How things are mounted in a cooler is discussed in the health code. While a USDA code exists, it is the local code, and the local interpretation, that governs.
Likewise, the hood installation will have to be approved by the local fire marshall. It's rather interesting, in that I have yet to find a jurisdiction that has actually adopted the NFPA 'hood codes.' Nor have I met the inspector who even has access to one - let alone read it! In such situations, anything you can produce will greatly help your case.
Which brings us to two of my pet peeves:
1) IMO, there are far too many codes= and inspecting agencies; and,
2) IMO, you simply cannot become a competent inspector by sitting in a classroom or going to seminars- you need to master the trade first. This trend to seminar-educated 'combination' inspectors is a travesty.
