Preface
This is the harmonized ANCE, CSA Group, and UL standard for grounding and bonding equipment. It is the second edition of NMX-J-590-ANCE, the seventh edition of CSA C22.2 No. 41, and the eleventh edition of UL 467. This edition of CSA C22.2 No. 41 supersedes the previous edition published in 2013. This edition of UL 467 supersedes the previous edition published in 2013.
This harmonized standard was prepared by the Association of Standardization and Certification (ANCE), the CSA Group, and Underwriters Laboratories Inc. (UL). The efforts and support of the Technical Harmonization Committee for Connectors, of the Council on the Harmonization of Electrotechnical Standards of the Nations of the Americas (CANENA), are gratefully acknowledged.
This Standard is considered suitable for use for conformity assessment within the stated scope of the Standard.
The present Mexican standard was developed by the CT Conductors from the Comite de Normalizacion de la Asociacion de Normalizacion y Certificacion, A.C., CONANCE, with the collaboration of the connectors manufacturers and users.
This standard was reviewed by the CSA Integrated Committee on Electrical Connectors, under the jurisdiction of the CSA Technical Committee on Wiring Products and the CSA Strategic Steering Committee on Requirements for Electrical Safety, and has been formally approved by the CSA Technical Committee. 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 applies to grounding and bonding equipment for use in accordance with CSA C22.1, Canadian Electrical Code, Part I in Canada, the National Electrical Code, NFPA 70, in the United States, or the Standard for Electrical Installations, NOM-001-SEDE, in Mexico.
1.2
This Standard applies to the following grounding and bonding equipment:
a) ground clamps, bonding devices, grounding bushings, water-meter shunts, grounding electrodes, and the like used in a grounding system;
b) equipment for making electrical connections between
i) the grounding conductors used in electrical power systems, non-current-carrying metal parts of electrical equipment, armored grounding wires, metal raceways, and the like; and
ii) grounding electrodes;
c) equipment for making electrical connections between
i) the grounding conductors used in telecommunications systems such as telephone, radio, CATV, network power broadband, and the like; and
ii) grounding electrodes;
d) hospital grounding jacks and mating grounding cord assemblies (for Mexico and the United States, see Annex A);
e) bonding devices for making electrical connections between
i) the hex head of a brass fitting used in a piping system in accordance with 250.104 of NFPA 70; and
ii) the grounding electrodes; and
f) intersystem bonding terminations for connecting intersystem bonding and grounding conductors for other systems in accordance with NFPA 70.
Notes:
1) In Canada, hospital grounding jacks are not defined in CSA C22.1, Canadian Electrical Code, Part I.
2) In Canada, ″mating ground cord assemblies″ are covered in CSA C22.2 No. 21 and CSA C22.2 No. 42.
