The National Electrical Installation Standards available from NECA

NECA is the voice of the technical contracting industry, focusing on:

General Contracting Installations
Lighting Installations
Limited Energy Installations
Power Distribution
Utilization Equipment
Wiring Methods
Standards in Development

One of the most important developments that NECA works on is the National Electrical Installation Standards (NEIS), which is developed by NECA and in partnership with other industry organizations. NEIS are the standards for electrical construction. In addition to the basic safety requirements available in the National Electrical Code (NEC), the National Electrical Installation Standards clearly define installation instructions of products and systems. It is important to mention that the NEIS are submitted for approval by the American National Standards Institute (ANSI).

Referencing NEIS:

Saves Spec-writing time
Controls over workmanship
Ensures long-term performance

Utilizing NEIS as enforcement in contracts can significantly reduce misunderstandings between Engineers, Electrical contractors, Owners, and Facility managers

With NEIS, the electrical installation you design not only meets code--it meets the shared expectations of everyone involved. Customers get a top-quality job, and you and your firm enjoy a reputation for long-term reliability.
