23、JUNE 26, 2015 CSA C22.2 NO. 62.1-15 UL 5A 4UL COPYRIGHTED MATERIAL NOT AUTHORIZED FOR FURTHER REPRODUCTION OR DISTRIBUTION WITHOUT PERMISSION FROM UL PREFACE This is the harmonized CSA Group and UL standard for Nonmetallic Surface Raceways and Fittings. It is the second edition of CSA C22.2 No. 62.1

24、, and the fourth edition of UL 5A. This edition of CSA C22.2 No. 62.1 supersedes the previous edition(s) published in 2003. This edition of UL 5A supersedes the previous edition(s) published on July 18, 2003. This harmonized standard was prepared by CSA Group and Underwriters Laboratories Inc. (UL).

25、 The efforts and support of the Technical Harmonization Subcommittee 23A SNR Working Group 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

26、 scope of the standard. This standard was reviewed by the CSA Subcommittee ICCM05 Surface Raceway Systems, 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 CS

27、A Technical Committee. This standard has been approved by the American National Standards Institute (ANSI) as an American National Standard. Application of Standard Where reference is made to a specic number of samples to be tested, the specied number is to be considered a minimum quantity. Note: Al

28、though the intended primary application of this standard is stated in its scope, it is important to note that it remains the responsibility of the users of the standard to judge its suitability for their particular purpose. Level of Harmonization This standard uses the IEC format but is not based on

29、, nor is it considered equivalent to, an IEC standard. This standard is published as an equivalent standard for 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 gove

30、rnmental regulations as well as those recognized as being in accordance with NAFTA Article 905, for example, because of fundamental climatic, geographical, technological, or infrastructural factors, scientic justication, or the level of protection that the country considers appropriate. Presentation

31、 is word for word except for editorial changes. Reasons for Differences From IEC The THSC determined the safe use of electrical surface raceway and ttings is dependent on the design and performance of the raceway and cable systems with which they are intended to be installed. Signicant investigation

32、 is required to assess safety and system compatibility issues that may lead to harmonization of traditional North American electrical raceway and ttings with those presently addressed in the known IEC standards. The THSC agreed such future investigation might be facilitated by completion of harmoniz

33、ation of the North American standards for electrical surface raceway and ttings.

34、ization of an identical or equivalent standard is based on the literal text to determine compliance with the standard in accordance with the procedural rules of the standards development organization. If more than one interpretation of the literal text has been identied, a revision is to be proposed

35、 as soon as possible to each of the standards development organizations to more accurately reect the intent.

38、ials not exceeding 600 V between conductors. 1.3 Nonmetallic raceways with metal covers are intended to enclose circuits operating at potentials in accordance with Table 1 or Table 1A. 1.4 These requirements do not cover surface metal raceways, cable trays, or wireways. 2 Denitions 2.1 For the purpo

39、se of this Standard, the following denitions apply: ACCESSORY a part that may be added to a raceway system for a special purpose (for example, guards, hangers, retainers). FITTING, RACEWAY a part used to connect, change direction, or terminate a surface raceway (for example, a transition coupler, an

40、 end cap, a corner, a tee, an adapter, or a box) or a system specic wiring device that completes the system. FIXTURE BOX a box used for the support of a lighting xture, lampholder, or other equipment intended for similar installation. GROUNDING/BONDING CONDUCTOR a conductor that is dened in the Nati

41、onal Electrical Code (NEC) as an Equipment Grounding Conductor, and a conductor that is dened in the Canadian Electrical Code (CE Code), Part I, as a Bonding Conductor. NONMETALLIC a polymeric part. SURFACE NONMETALLIC RACEWAY a raceway for surface or suspension mounting with a nonmetallic base and

42、a nonmetallic or metal cover. SURFACE RACEWAY SYSTEM a system consisting of a surface raceway and associated ttings, which may include wiring devices and accessories. WIRING DEVICE a part of an electrical system intended to carry, provide a means of connection to, or provide control of electrical en

43、ergy within a raceway system (for example, switches or receptacles). 3 General 3.1 General requirements 3.1.1 For products intended for use in Canada, general requirements are given in CSA Standard C22.2 No. 0, General Requirements Canadian Electrical Code, Part II.
