What is the National Electrical Code

The NEC is part of the National Fire Codes series published by the National Fire Protection Association and is also known as NFPA 70.

The NEC is commonly adopted by state or local law, as well as in many jurisdictions outside of the United States.

The NEC is updated and published every three years.

The 2014 Code is the most recent edition of the National Electrical Code.
Most states adopt the most recent edition within a couple of years of its publication.

As with any "uniform" code, a few jurisdictions regularly omit or modify some sections, or add their own requirements (sometimes based upon earlier versions of the NEC, or locally accepted practices).

It is in the best interest for all locations and jurisdictions, city and state building departments to adopt and enforce building codes that specify standards and practices for electrical systems to maintain safe wiring codes to maintain safe dwellings and environments for occupants.
