National Electric Code
One of the most important documents you'll need before installing your emergency lighting and exit sign fixtures is the thousand-page document called the National Electric Code (NEC). All of the products we carry are NEC-compliant unless otherwise noted.
The NEC has been updated every three years and was first printed in 1897. Its purpose is to codify the requirements for the safe installation of electronic appliances including emergency lights and powered exit signs. It is part of the National Fire Code series and published by the National Fire Protection Agency (NFPA).
The NEC is so widely used as a benchmark, it is approved as an American national standard by the American National Standards Institute (ANSI) and is also referred to as the ANSI/NFPA 70. However the NEC is not written law, though it is mandated by nearly every state and local law. Such principalities are free to amend the NEC to fit their requirements. States or cities can even abandon the NEC if they provide sufficient fire protection laws, though most prefer to modify it.
