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.

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 electrical system must conform to the electrical code in who's jurisdiction it is to be built. Most electrical engineers when designing a system use the code book constantly. In actual fact they over design above what the code book calls for as the code book rules are the minimum requirements for safe installations.
