Preface 

This is the harmonized ANCE, CSA Group, and UL standard for sealed wire connector systems. It is the fourth edition of NMX-J-519-ANCE, the fourth edition of CSA C22.2 No. 198.2, and the seventh edition of UL 486D. This edition of NMX-J-519-ANCE supersedes the previous edition published in 2015. This edition of CSA C22.2 No. 198.2 supersedes the previous edition published in 2015. This edition of UL 486D supersedes the previous edition published in 2015. This harmonized standard was prepared by the Association of Standardization and Certification (ANCE), CSA Group, and ULSE. The efforts and support of the Technical Harmonization Committee for Connectors, THC 99, 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 SC 20D – Conectadores part of the CT 20 – Conductores 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 The requirements in this standard cover sealed wire connector systems, including insulating caps, covers, resins, tubing, and tapes provided with, or for use with, specific wire connectors. These systems are intended for wet or damp locations and other installations such as: a) Direct burial, b) Below grade, c) Above grade where exposed to sunlight; or d) Where exposed to sea water or salt water. The wire connectors covered by these requirements are intended for use with copper conductor, aluminum conductor, or both in accordance with installations covered by the National Electrical Code, NFPA 70; CSA C22.1, Canadian Electrical Code, Part I; and NOM 001 SEDE, Standard for Electrical Installations. 

1.2 These requirements apply to sealed wire connector systems intended for use at 1500 V or less, with currents not exceeding the ampacity of insulated conductor types noted below, rated either 75 °C (167 °F) or 90 °C (194 °F): a) 14 AWG (2.08 mm2) through 2,000 kcmil (1,012 mm2) conductors: Types RHW, RHW-2, USE, USE-2, USEB90, USEI75, USEI90, THW, XHHW, XHHW-2, RW90 EP, RW90 XLPE , or TWU, b) 30 AWG (0.05 mm2) through 16 AWG (1.31 mm2) conductors: Any Type insulation acceptable for direct burial, below grade use, or wet locations. 

1.3 These requirements also cover sealed wire connector systems intended for use with single or multiple conductor underground feeder cable, golf course sprinkler cable, underground low energy cable, irrigation cable, or other cable with insulation acceptable for direct burial, below grade use, or wet locations. 

1.4 This standard does not apply to twist-on style splicing sealed wire connectors.
