NEC 2005 Article 90.4 - "This code is intended to be suitable for mandatory application by governmental bodies that exercise legal jurisdicition over electrical installations, including signaling and communications systems, and for use by insurance inspectors. The authority having jurisdiction for enforcement of the code has the responsibility for making interpretations of the rules, for deciding on the approval of equipment and materials, and for granting the special permission contemplated in a number of the rules."
In most countries, regulations and standards related to electrical wiring are determined by a national or regional electrical code, such as the National Electrical Code (NEC) in the United States or the IEC (International Electrotechnical Commission) standards in Europe. These codes are typically developed by governmental or industry organizations to ensure the safety and reliability of electrical installations.
The National Electrical Code (NEC) permits a minimum wire size of 14 AWG for general lighting and receptacle circuits in parallel installations.
The National Electric Code typically governs local permits for electrical work where adopted. There are updates to the NEC every three years. Local electric license authorities adopt a specific edition of the NEC to govern local permits and updates from time to time as new editions become available.

The National Electric Code is updated yearly and is usually adopted by a locality some years after release. You can check with your local license and permit office what version is in effect in your locale or ask an electrician. It contains the rules for all types of electric work. In the United States, the NEC is updated every 3 years on a very strict schedule and it is adopted by local jurisdictions at their discretion. It is not a government document until it is adopted by someone. The most recent update is the 2011 version. I know that Master Electrician tests are not yet based on it. Depending on the jurisdiction you may find a version as old as the 1999 NEC still in effect.

The national electrical code is a publication thet governs commercial, residential and industrial electrical installations. Article 250 is the section governing grounding and bonding installations.
The National Electrical Code (NEC) requires that conduit fill in electrical installations should not exceed 40 of the cross-sectional area of the conduit to ensure safe and efficient wiring.

The National Electrical Code (NEC) permits a minimum wire size of 14 AWG for general lighting and receptacle circuits in parallel installations.
The conduit size chart in the National Electrical Code (NEC) provides information on the maximum number and size of conductors that can be safely installed in a specific conduit size. This helps determine the appropriate conduit size for electrical installations to ensure compliance with safety standards and prevent overheating or other hazards.
The National Electrical Code is the recognised standard to which all electrical wiring and installations must adhere to. It is a requirement of selling a house that all wiring and equipment must feature this code to prove it has been correctly fitted.
National Electrical Contractors Association was created in 1901.
National Association of Electrical Distributors was created in 1908.
The National Electric Code typically governs local permits for electrical work where adopted. There are updates to the NEC every three years. Local electric license authorities adopt a specific edition of the NEC to govern local permits and updates from time to time as new editions become available.
