Standards as High as Your Own
National Electrical Installation Standards are the first quality standards for electrical construction, developed by the National Electrical Contractors Association (NECA), in partnership with several industry organizations, to clearly define the actions needed to perform an installation in a “neat and workmanlike manner”, as often referenced in the NEC.
NECA is in the process of creating and revising several National Electrical Installation Standards (NEiS), and would like you to participate!
