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.
As with any code compiled by a governing body it has to be complied with. This is for the protection of the consumer. Major projects should be left to a licensed electrical contractor to take out the proper permits and call for proper inspections. By taking this route it will leave you confident that if any mishaps happen to the installation down the road your insurance company will be behind you 100%.
Anyone who attempts to make electrical installations, changes, repairs to electrical wiring or facility.
The electrical code is there to protect everyone against inexperience and sloppiness.
For example, if a contractor or handyman decides to add outlets to your garage and does not follow the code which in turn causes property or physical damage to others. That contractor may be liable for the losses.
If you must do electrical work to your property, you can contact your local inspector for guidance and inspection.
The national electrical code is a minimum set of standards used to protect persons and property regarding the installation of all electrical equipment. It is a protection for people.
