 What Do They Mean?
National Electrical Installation Standards are the first quality standards for electrical construction. They provide critical guidance to the specifiers, builders, inspectors, and users of building electrical systems.
Simply following the National Electrical Code (NEC) won’t always insure that a project performs at maximum reliability and efficiency. National Electrical Installation Standards supplement important Code safety rules with additional performance requirements.
In particular, National Electrical Installation Standards define what is meant by installing electrical equipment “in a neat and workmanlike manner,” as required by the NEC. This places issues of quality and workmanship in the contract documents, where they can be enforced legally.
NEIS are published by the National Electrical Contractors Association (NECA), developed in cooperation with other industry expert groups, and approved by the American National Standards Institute (ANSI).
Who Receives The NEIS?
The Quad Cities Chapter of NECA mails, free of charge, a copy of each standard to Electrical Inspectors in the Quad Cities and Muscatine. They are also mailed to all area Construction Engineers as well as all members of NECA. Additional copies are $25.00 each.
