Description

Preface This is the harmonized ANCE, CSA Group, and UL standard for Thermoset-Insulated Wires and Cable s. It is the Sixth edition of NMX-J-451-ANCE, the Eleventh edition of CSA C22.2 No. 38, and the Nineteenth edition of UL 44. This edition of NMX-J-451-ANCE supersedes the previous edition published in March 28, 2014. This edition of CSA C22.2 No. 38 supersedes the previous edition published in March 28, 2014. This edition of UL 44 supersedes the previous edition published in March 28, 2014. This harmonized standard has been jointly revised on May 14, 2021. For this purpose, CSA Group and UL are issuing revision pages dated May 14, 2021, and ANCE is issuing a new edition dated May 14, 2021. This harmonized standard was prepared by the Association of Standardization and Certification, (ANCE), CSA Group and Underwriters Laboratories Inc. (UL). The efforts and support of the Technical Harmonization Committee for Electrical Wires and Cables, 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 20 Conductores from the Comite de Normalizacion de la Asociacion de Normalizacion y Certificacion, A.C., CONANCE, with the collaboration of the SC 20B Conductores para Baja Tensión. This standard was reviewed by the CSA Integrated Committee on Fixed Installation Wires and Cables, 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. This standard has been approved by the American National Standards Institute (ANSI) as an American National Standard. Scope 1.1 This Standard specifies the requirements for single-conductor and multiple-conductor thermoset-insulated wires and cables rated 600 V, 1000 V, 2000 V, and 5000 V, for use in accordance with the rules of the Canadian Electrical Code, Part I, CSA C22.1, in Canada, Standard for Electrical Installations, NOM-001-SEDE, in Mexico, and the National Electrical Code (NEC), NFPA 70, in the United States of America. See Annex A for the complete list of types and voltage ratings covered by this Standard and the specific electrical codes for which they are intended, and Annex B for a summary of construction and test requirements for these types. 1.2 Table 1 provides a summary of the maximum conductor temperature, voltage ratings, and the number of insulated conductors for the types to which this Standard applies. 1.3 This Standard also specifies the requirements for submersible pump cables, with or without jackets, in Deep Well Submersible Water-Pump Cable, Section 7. No type-letter designations are assigned to these cables. 1.4 Products within this Standard might have applications not covered by the electrical codes listed in 1.1.
