If you're an electrician then you know: the NEC, or National Electrical Code, is the gospel. NEC is the absolute authority when it comes to everything from studying to becoming an electrician to how to do your job 20 years on. The National Electrical Code for electricians is like the air that they breathe.
The NEC Code is published by the National Fire Prevention Association and while its is not the law of the land, it is very often adopted by states for safe practices. Many states even mandate or ammend it to codify state and local laws.
