Overview In order to align the technical requirements of Electric Vehicle Supply Equipment (EVSE) intended for the North American market, CSA Group has published standards whose content has been harmonized for Canada, the U.S. and Mexico. This new harmonized standard contains the construction and performance requirements that are applied to a device that is intended to become an integral part of an overall device or charging system. This standard works in conjunction with C22.2 NO. 281.1-12 - Standard for Safety for Personnel Protection Systems for Electric Vehicle (EV) Supply Circuits: General Requirements.

Preface This is the harmonized ANCE, CSA Group, and UL Standard for Safety for Personnel Protection Systems for Electric Vehicle (EV) Supply Circuits: Particular Requirements for Protection Devices for Use in Charging Systems. It is the Second edition of NMX-J-668-2-ANCE, the First edition of CAN/CSA-C22.2 No. 281.2, and the Second edition of UL 2231-2. This harmonized standard has been jointly revised on December 15, 2020. For this purpose, CSA Group and UL are issuing revision pages dated December 15, 2020, and ANCE is issuing a new edition dated December 15, 2020. This standard has been developed in compliance with Standards Council of Canada requirements for National Standards of Canada. It has been published as a National Standard of Canada by CSA Group. Scope 1.1 This Standard is intended to be read together with Annex A, Ref. No. 1. The requirements of Annex A, Ref. No. 1 apply unless modified by this Standard.
