The site navigation utilizes arrow, enter, escape, and space bar key commands. Left and right arrows move across top level links and expand / close menus in sub levels. Up and Down arrows will open main level menus and toggle through sub tier links. Enter and space open menus and escape closes them as well. Tab will move on to the next part of the site rather than go through menu items.


NECA offers a variety of ANSI-Approved performance and workmanship industry standards for electrical construction. NEIS™ are used by construction owners, specifiers, and contractors to clearly illustrate the performance and workmanship standards essential for different types of electrical construction. NEIS™ are also referenced throughout the National Electrical Code.

The Idea Behind NEIS

The National Electrical Installation Standards (NEIS™), all started with a simple question: “What constitutes good Workmanship?”

The National Electrical Code (NEC®) requires mechanical execution of work, and installations to be professional and skillful. However, these terms are not defined, and it is often left up to the determination of the AHJ, leaving a gap between the bare minimum Code requirements, and a professional and skillful installation. In the early 1990s NECA set out to bridge this gap by developing the NEIS™ taking on the challenge of defining what “Good Workmanship” is when it comes to electrical construction. NECA saw a need and benefit for both contractors and their customers by addressing the performance and quality issues that were not addressed directly in the NEC®. Electrical installations demand precision and careful artisanship. Today, NECA’s library of Standards contains forty-six (46) installation standards on a wide variety of topics, clearly identifying the necessary steps needed to achieve Good Workmanship in Electrical Construction.
