New Editions Of The NEC Are Not Immediately Adopted
Not necessarily. The NEC has been updated every three years since it originated back in 1897, but the code does not automatically become a national standard. Each new edition must be adopted by the state or local jurisdiction, and some of them take a few years to move up.
As of early 2018, for example, the 2008 NEC was still effective in five states, and four other states were continuing to use the 2011 edition. Some states have their own electrical code, which is based on a particular edition of the NEC, but with amendments. You can do a Google search for “NEC adoption maps” to check the current status of your state. Also, a local jurisdiction may choose not to enforce certain citations in the code.
