Preface

This is the harmonized ANCE, CSA Group, and UL Standard for Grounding and Bonding Equipment. It is the first edition of NMX-J-590-ANCE, the sixth edition of CSA C22.2 No. 41, and the tenth edition of UL 467. This edition of CSA C22.2 No. 41 supersedes the previous edition published in 2007. This edition of UL 467 supersedes the previous edition published in 2007.

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.

Scope

1.1 This Standard applies to grounding and bonding equipment for use in accordance with the Canadian Electrical Code, Part I, CSA C22.1, 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

1. 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



2. grounding electrodes;

c) equipment for making electrical connections between

1. the grounding conductors used in telecommunications systems such as telephone, radio, CATV, network power broadband, and the like; and



2. 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

1. the hex head of a brass fitting used in a piping system in accordance with 250.104 of NFPA 70; and



2. 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.
