Product Details
Preface
This is the harmonized ANCE, CSA Group, and ULSE standard for Ground-Fault Circuit-Interrupters. It is the third edition of NMX-J-520-ANCE, the second edition of CSA C22.2 No. 144.1, and the fifth edition of UL 943. This harmonized standard has been jointly revised on September 5, 2023. For this purpose, CSA Group and ULSE are issuing revision pages dated September 5, 2023, and ANCE is issuing a new edition dated September 5, 2023.
This harmonized Standard was prepared by the Association of Standardization and Certification (ANCE), CSA Group, and ULSE. The efforts and support of the CANENA Technical Harmonization Subcommittee 23E, Ground-Fault Circuit-Interrupters, 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 23 Accesorios Electricos from the Comite de Normalizacion de la Asociacion de Normalizacion y Certificacion, A.C., CONANCE, with the collaboration of the ground fault circuit interrupters manufacturers and users.
This Standard was reviewed by the CSA Subcommittee on Ground-Fault Circuit-Interrupters, under the jurisdiction of the CSA Technical Committee on Industrial Products and the CSA Strategic Steering Committee on Requirements for Electrical Safety, and has been formally approved by the CSA Technical Committee.
Scope
1.1
This Standard applies to Class A, single- and three-phase, ground-fault circuit-interrupters intended for protection of personnel, for use only in grounded neutral systems in accordance with the National Electrical Code (NEC), ANSI/NFPA 70, the Canadian Electrical Code, Part I, and Electrical Installations (Use), NOM-001-SEDE. These devices are intended for use on alternating current (AC) circuits of 120 V, 208Y/120 V, 120/240 V, 127 V, or 220Y/127 V, 60 Hz circuits.
Note - In Canada, the text intended for protection of personnel is excluded.
1.2
These requirements do not cover ground-fault circuit-interrupters intended for use in circuits served by a transformer having windings wholly insulated from each other.
1.3
This Standard applies to all Class A ground-fault circuit-interrupters. These Class A GFCIs are permitted to be integrated into other devices, in which case, besides complying with this Standard, these devices are to comply with the corresponding applicable Standard for the device in question.
1.4
This Standard includes minimum requirements for the function, construction, performance, and markings of ground-fault circuit-interrupters included in the scope.
1.5
This Standard is intended to cover only Class A GFCI devices.
1.6
This Standard also covers GFCIs of the self contained type that are intended for installation in a counter, such as would be suitable for installation in a kitchen or bathroom counter top.
