NEIS Standards are available for a variety of categories. To view existing Standards or Standards in development, choose one of the categories listed below.
The complete set of National Electrical Installation Standards in paper book format.
These custom binders feature striking full-color graphics on the cover and spine, opens flat for easy use.
This publication describes graphic symbols used to represent electrical wiring and equipment on construction drawings,. In this publication, the term “electrical” is used to include electrical, electronic, and communications systems covered by the National Electrical Code (NFPA 70). This publication also summarizes recommended drawing practices for electrical construction drawings.
Describes installation procedures for Type AC and Type MC cables, which are used for electrical wiring for residential, commercial, and industrial occupancies. It also includes information on fittings and other accessories necessary for a quality installation and maintenance of these cable systems. NECA 120 is approved as an American National Standard (ANS).
This standard describes recommended procedures for selecting and installing stationary electric motors and motor controllers rated 1000 volts or less. It also covers routine maintenance procedures to be followed after the installation is complete.
Describes fire alarm system job practices for installing, testing, and maintaining fire alarm systems. These job practices represent a minimum level of quality for fire alarm system installations. NECA 305 was revised in 2010 and is approved as an American National Standard (ANS).
Describes installation and maintenance practices for motor control centers rated 600 volts or less. It also covers periodic routine maintenance procedures for motor control centers and special procedures to be used after adverse circumstances, such as a short-circuit, ground-fault, or immersion in water. NECA 402 is approved as an American National Standard (ANS).
Describes installation procedures for (a) Generator sets permanently installed at one-family dwellings to provide backup power, typically rated 120/240 volts, single-phase, three-wire; and (b) Generator sets fueled by gasoline, natural gas, or liquified petroleum (LP) gas. NECA 406 is approved as an American National Standard (ANS).
This standard describes installation procedures for pad-mounted, sealed, self-cooled or fan-cooled, compartmental, single- and three-phase liquid filled distribution and power transformers with primary windings rated from 2400 volts to 35 kV AC, nominal, and rated from 75 kVA through 5000 kVA, and associated accessories, designed for outdoor installation at grade level with underground entrance of primary and secondary conductors, and used for supplying power, heating and lighting loads for commercial, institutional, and industrial use in nonhazardous locations.
Describes installation and maintenance procedures for permanently installed, static, three-phase Uniterruptible Power Supplies (UPS) rated 30 kVA or more and rated 600 volts or less and related battery systems installed indoors and outdoors for commercial, institutional, and industrial applications. NECA 411 is approved as an American National Standard (ANS).
This standard describes application and installation practices and procedures for low-voltage, medium-voltage, and high-voltage fuses. This publication applies to all classifications of fuses used for overcurrent protection of distribution, utilization, and control equipment used for power, heating, and lighting loads for commercial, institutional, and industrial use in nonhazardous indoor and outdoor locations.
Describes installation of medium-voltage metal-clad switchgear. NECA 430 is approved as an American National Standard (ANS).
NECA 700 describes various application procedures for selecting and adjusting low-voltage overcurrent protective devices to achieve selective coordination. NECA 700 is approved by the American National Standards Institute (ANSI) as an American National Standard.
This standard describes installation procedures and design considerations for aluminum building wire and cable in residential, commercial, institutional and industrial applications not exceeding 2000 volts.
Developed jointly with the Aluminum Association, NECA/AA 104-2012 is approved as an American National Standard (ANS).
This standard describes installation procedures for shielded and non-shielded solid-dielectric medium-voltage cables rated from 2001 Volts to 35,000 Volts AC and installed in conduits or ducts, or direct-buried. This publication applies to single-and multi-conductor cables used for distributing power for commercial, institutional, and industrial loads in nonhazardous locations both indoors and outdoors.
This standard describes installation practices and procedures for metal cable tray systems. Details about maintenance, system modification, grounding and bonding, and inspection and addition of cables are complemented by illustrations throughout. A full list of reference standards is also included.
This reference tool is a complete digital collection of NECA’s performance standards for electrical construction and maintenance. It contains the complete set of NEIS, including updated and new standards series through 2016. Several NEIS in the Yearbook have been revised and expanded to align with the current edition of the National Electrical Code and other applicable standards.
