24、NCE, CSA Group, and UL standard for Metallic Outlet Boxes. It is the third editionof NMX-J-023/1-ANCE, the second edition of CSA C22.2 No. 18.1, and the eleventh edition of UL 514A.This edition of CSA C22.2 No. 18.1 supersedes the previous edition(s) published in 2004. Thisharmonized standard has be
25、en jointly revised on August 11, 2017. For this purpose, ANCE, CSA Groupand UL are issuing revision pages dated August 11, 2017.This harmonized standard was prepared by the Association of Standardization and Certification (ANCE),CSA Group, and Underwriters Laboratories Inc. (UL). The efforts and sup
26、port of the TechnicalHarmonization Committee for Switch and Outlet Boxes, of the Council on the Harmonization ofElectrotechnical Standards of the Nations of the Americas (CANENA), are gratefully acknowledged.This standard is considered suitable for use for conformity assessment within the stated sco
27、pe of theStandard.The present Mexican standard was developed by the CT committee named from the Comite deNormalizacion de la Asociacion de Normalizacion y Certificacion, A.C., CONANCE, with the collaborationof the type of manufacture manufacturers and users.This standard was reviewed by the CSA Inte
28、grated Committee on Wiring Devices, under the jurisdictionof the CSA Technical Committee on Wiring Products and the CSA Strategic Steering Committee onRequirements for Electrical Safety, and has been formally approved by the CSA Technical Committee.This standard has been approved by the American Nat
29、ional Standards Institute (ANSI) as an AmericanNational Standard.Application of StandardWhere reference is made to a specific number of samples to be tested, the specified number is to beconsidered a minimum quantity.Note: Although the intended primary application of this standard is stated in its s
30、cope, it is important to note thatit remains the responsibility of the users of the standard to judge its suitability for their particular purpose.Level of HarmonizationThis standard uses the IEC format but is not based on, nor is it to be considered equivalent to, an IECstandard. This standard is p
31、ublished as an equivalent standard for ANCE, CSA Group, and UL.An equivalent standard is a standard that is substantially the same in technical content, except as follows:Technical national differences are allowed for codes and governmental regulations as well as thoserecognized as being in accordan
32、ce with NAFTA Article 905, for example, because of fundamental climatic,geographical, technological, or infrastructural factors, scientific justification, or the level of protection thatthe country considers appropriate.

33、-023/1-ANCE CSA-C22.2 NO. 18.1-13 UL 514A8Reasons for differences from IECThe Technical Harmonization Committee identified the following IEC standard within the scope of thisstandard: IEC 60670 (1989-11), General requirements for enclosures for accessories for household andsimilar fixed electrical i
34、nstallations and Amendment No. 1 (1994-01). It was further recognized thatsignificant revision of this IEC standard is in process, with participation by the IEC National Committeesin each of the three countries that are party to this standard.The THC determined that the safe use of electrical boxes
35、is critically dependent on the design andperformance of the system with which they are intended to be installed. Significant investigation isrequired to assess safety and system compatibility issues that may lead to harmonization of traditionalNorth American electrical boxes with those presently add
36、ressed in the known IEC standards. The THCagreed such future investigation might be facilitated by completion of harmonization of the North Americanstandards for electrical boxes.InterpretationsThe interpretation by the standards development organization of an identical or equivalent standard isbase
37、d on the literal text to determine compliance with the standard in accordance with the proceduralrules of the standards development organization. If more than one interpretation of the literal text has beenidentified, a revision is to be proposed as soon as possible to each of the standards developm
38、entorganizations to more accurately reflect the intent.AUGUST 11, 2017 NMX-J-023/1-ANCE CSA-C22.2 NO. 18.1-13 UL 514A 9Metallic Outlet Boxes1 Scope1.1 This standard applies to metallic OUTLET BOXES, flush-DEVICE BOXES, FLOOR BOXES, CONCRETE BOXES, EXTENSIONRINGS, covers, CONDUIT BODIES, BAR HANGERS,
