NEC Code Regulations by State

By superadmin

Homelectrical.com has customers all over the United States, and each State has its own rules and regulations when it comes to electrical device installation and building code. Since many of our customers are Do-it-Yourselfers, we have created a reference guide to help you make the correct purchase of electrical devices and components to fit your needs and to follow the regulations used in your area. Below you will find a chart listing the State, what NEC code version they follow, and when that code was adopted and implemented. If you do not know what code your particular area in any State uses, please contact a licensed electrician.
