scope:

This standard describes the procedures for installing and maintaining AC Level 1, AC Level 2 and fast charging DC (initially known in the industry as AC Level 3 and currently known in the industry as DC Level 2) Electric Vehicle Supply Equipment (EVSE).

Products and Applications Included

This Standard applies to Electric Vehicle Supply Equipment (EVSE) that complies with applicable local, state and federal regulations, codes, and standards for AC Level 1, AC Level 2 and fast charging DC (DC Level 2) EVSE intended for transferring energy between premises wiring systems and electric vehicles (EVs) by conductive, inductive, or wireless power transfer (contactless inductive charging) means.

Products and Applications Excluded

This Standard does not apply to other than Code compliant AC Level 1, AC Level 2 and fast charging DC (DC Level 2) EVSE, as well as off-road, self-propelled electric vehicles, such as industrial trucks, hoists, lifts, transports, golf carts, airline ground support equipment, tractors, boats, and the like.

Regulatory and Other Requirements

All information in this publication is intended to conform to the NEC (ANSI/NFPA 70). Installers shall follow the NEC, applicable state and local codes, manufacturer instructions, and contract documents when installing and maintaining Electric Vehicle Supply Equipment (EVSE).

Only qualified persons as defined in the NEC familiar with the construction and installation of Electric Vehicle Supply Equipment (EVSE) shall perform the technical work described in this publication. Administrative functions and other non-technical tasks can be performed under the supervi-sion of a qualified person. All work shall be performed in accordance with NFPA 70E, Standard for Electrical Safety in the Workplace.

General requirements for installing electrical products and systems are described in NECA 1, Standard for Good Workmanship in Electrical Construction (ANSI). Other NEIS provide additional guidance for installing particular types of electrical products and systems. A complete list of NEIS is provided in Annex C.

Mandatory Requirements, Permissive Requirements, Quality and Performance Instructions, Explanatory Material, and Informative Annexes

Mandatory requirements in manufacturer instructions, or of Codes or other mandatory Standards that may or not be adopted into law, are those that identify actions that are specifically required or prohibited and are characterized by the use of the terms "must" or "must not," "shall" or "shall not," or "may not," or "are not permitted," or "are required," or by the use of positive phrasing of mandatory requirements. Examples of mandatory requirements may equally take the form of, "equipment must be protected," "equipment shall be protected," or "protect equipment," with the latter interpreted (understood) as "(it is necessary to) protect equipment."

Permissive requirements of manufacturer instructions, or of Codes or other mandatory Standards that may or not be adopted into law, are those that identify actions that are allowed but not required, or are normally used to describe options or alternative means and methods, and are characterized in this Standard by the use of the terms "may," or "are permitted," or "are not required."

Quality and performance instructions identify actions that are recommended or not recommended to improve the overall quality or performance of the installation and are characterized by the use of the terms "should" or "should not."

Explanatory material, such as references to other Codes, Standards, or documents, references to related sections of this Standard, information related to another Code, Standard, or document, and supplemental application and design information and data, is included throughout this Standard to expand the understanding of mandatory requirements, permissive requirements, and quality and performance instructions. Such explanatory material is included for information purposes only, and is identified by the use of the term "NOTE," or by the use of italicized text.

Non-mandatory information and other reference standards or documents relative to the application and use of materials, equipment, and systems covered by this Standard are provided in informative annexes. Informative annexes are not part of the enforceable requirements of this Standard, but are included for information purposes only.
