Once the coding model has been accepted as law, it loses copyright protection and may be freely obtained at no cost. The NEC is composed of an introduction, nine chapters, annexes A through J, and the index. The introduction sets forth the purpose, scope, enforcement, and rules or information that are general in nature. The first four chapters cover definitions and rules for installations voltages, connections, markings, etc. The next three chapters deal with special occupancies high risk to multiple persons , special equipment signs, machinery, etc. and special conditions emergency systems, alarms, etc. and chapter 9 is composed of tables regarding conductor, cable and conduit properties, among other things.
Annexes A-J relate to referenced standards, calculations, examples, additional tables for proper implementation of various code articles for example, how many wires fit in a conduit and a model adoption ordinance. Articles are coded with numerals and letters, as. For example, inclusion a Other Circuits, precise inclusion 1 Class 2 and Class For internal references, some lengthy articles are further broken into "parts" with Roman-numerals parts I, II, III, etc. Each code article is numbered based on the chapter it is in. Those wiring methods acceptable by the NEC are found in chapter 3, thus all approved wiring method code articles are in the s. Efforts have been underway for some time to make the code easier to use. Some of those efforts include using the same extension for both code articles and for the support of wiring methods. The NFPA also publishes a 1,page NEC Handbook for each new NEC edition that contains the entire code, plus additional illustrations and explanations, and helpful cross-references within the code and to earlier versions of the code.
The explanations are only for reference and are not enforceable. Many NEC requirements refer to "listed" or "labeled" devices and appliances, and this means that the item has been designed, manufactured, tested or inspected, and marked in accordance with requirements of the listing agency. To be listed , the device must meet testing and other requirements set by a listing agency such as Underwriters Laboratories UL , SGS North America, Intertek Formerly ETL , Canadian Standards Association CSA , or FM Approvals FM. These are examples of "national recognized testing laboratories" NRTL approved by the U. Department of Labor's Occupational Safety and Health Administration OSHA under the requirements of 29 CFR Upon payment of an investigation fee to determine suitability, an investigation is started. To be labeled as fit for a particular purpose for example "wet locations", "domestic range" a device must be tested for that specific use by the listing agency and then the appropriate label applied to the device.
A fee is paid to the listing agency for each item so labeled, that is, for each label. Most NRTLs will also require that the manufacturer's facilities and processes be inspected as evidence that a product will be manufactured reliably and with the same qualities as the sample or samples submitted for evaluation. An NRTL may also conduct periodic sample testing of off-the-shelf products to confirm that safety design criteria are being upheld during production. Because of the reputation of these listing agencies, the "authority having jurisdiction" or "AHJ" — as they are commonly known usually will quickly accept any device, appliance, or piece of equipment having such a label, provided that an end user or installer uses the product in accordance with manufacturer's instructions and the limitations of the listing standard.
However, an AHJ, under the National Electrical Code provisions, has the authority to deny approval for even listed and labeled products. Likewise, an AHJ may make a written approval of an installation or product that does not meet either NEC or listing requirements, although this is normally done only after an appropriate review of the specific conditions of a particular case or location. The electric code makes a distinction between "high" voltages above volts, and "low" voltages below that. For circuits defined as low voltage, in some jurisdictions, there is no requirement for licensing, training, or certification of installers, and no inspection of completed work is required, for either residential or commercial work.
Low voltage cabling run in the walls and ceilings of commercial buildings is also typically excluded from the requirements to be installed in protective conduit. The precise reasoning for the selection of volts as the division between high and low is not clearly defined, but appears to be based on the idea that a person could touch the wires carrying low voltage with dry bare hands, and not be electrocuted, injured, or killed. This is generally true for 12 volt systems, but becomes more ambiguous as the voltage increases to volts. The meaning also varies when alternating current is used, as there is the more commonly known root mean square voltage V but also a peak wave voltage V. Telephones for example use low voltage cabling, but the ringing voltage from the central office has an RMS voltage of V. Although low voltage cabling does not require inspection or training to install in some jurisdictions, it is still important for installers to be aware of specific safety rules such as how to correctly penetrate building fire barriers.
Article addresses "branch circuits" as opposed to service or feeder circuits and receptacles and fixtures on branch circuits.

So, if you get your code adopted into law, it seems the government may be obligated to direct thousands of people into your sales and marketing funnel using taxpayer dollars. We are waiting to see if the governments agree that this arrangement is legitimate, especially in light of the previous court ruling mentioned earlier in this article. The matter is not yet settled. But this will be a court case worth following. Theft of private property is illegal. We are going to have to wait and see if the courts rule whether the NEC, once adopted into law, is private property or not. They will tell us what we are allowed to do. Privitizing codes which have the force of law is unsupportable.
Such codes have no meaning and should be widely IGNORED. There is no safety in the unknown. I think that if the NFPA is going to sue anyone they should be suing the states adopting their code into law. That in itself is the copy write infringement. It is in the interest of the federal and local government to protect the general public by enacting laws electrical safety guidelines, rules, measures, means and regulations into law. The law is public domain and meant to be published free of charge for the commonwealth of every US citizen. I think not. Take a good look at our constitution and the bill of rights.
