National Electrical Installation Standards (NEIS) are American National Standards (ANSI) developed by installation experts, manufacturers, contractors, engineers and end-users. NEIS include the industry-recognized best practices for installing and maintaining electrical systems and equipment for safety, efficiency and proper operation. 

For engineers, NEIS removes the time-consuming research and guesswork. Installation and maintenance procedures are clearly described. NEIS emphasize the critical elements of each system or equipment, and thoroughly address all facets of product installation where applicable, including field measurements, placing the order, receiving shipments, inspecting, handling and material storage, rough-in, installation, start-up, testing, commissioning, troubleshooting and maintenance.

Following NEIS assures owners, customers and end-users that their electrical systems are not only Code compliant, but also incorporate the industry-recognized best practices for safety, operation, maintenance, energy efficiency and power quality.
