22、UL standard for Electrical Quick-Connect Terminals. It is the Third edition of CSA-C22.2 No. 153 and the Ninth edition of UL 310. This edition of CSA C22.2 No. 153 supersedes the previous edition published in 2009. This edition of UL 310 supersedes the previous edition published May 27, 2009. This h

23、armonized standard was prepared by the CSA Group and Underwriters Laboratories Inc. (UL). The efforts and support of the CANENA Technical Harmonization Subcommittee 99, Electrical Quick-Connect Terminals, are gratefully acknowledged. This Standard is considered suitable for use for conformity assess

24、ment within the stated scope of the Standard. 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 for

25、mally approved by the CSA Technical Committee. This Standard was reviewed by ULs Standards Technical Panel (STP) for Electrical Quick-Connect Terminals, STP 310. This standard has been approved by the American National Standards Institute (ANSI) as an American National Standard. Where reference is m

26、ade to a specic number of samples to be tested, the specied number is considered a minimum quantity. Note: Although 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 suitabili

27、ty for their particular purpose. Level of harmonization This standard uses the IEC format but is not based on, nor is it considered equivalent to, an IEC standard. This standard is published as an identical standard for CSA Group and UL. An identical standard is a standard that is exactly the same i

28、n technical content except for national differences resulting from conicts in codes and governmental regulations. Presentation is word for word except for editorial changes. Reasons for differences from IEC This standard provides requirements for electrical quick-connect terminals for use in accorda

29、nce with the electrical installation codes of Canada and the United States. At present there is no IEC Standard for electrical quick-connect terminals for use in accordance with these codes. Therefore, this standard does not employ any IEC Standard for base requirements. OCTOBER 17, 2014 CSA-C22.2 N

34、 and tabs, having nominal widths of 2.8, 3.2, 4.8, 5.2, and 6.3 mm (0.110, 0.125, 0.187, 0.205, and 0.250 in). They are intended for internal wiring connections in electrical equipment and for the eld termination of conductors to electrical equipment in accordance with Part I of the Canadian Electri

35、cal Code, C22.1, in Canada, and the National Electrical Code, NFPA 70, in the United States of America. 1.2 These requirements apply to quick-connect terminals intended for use with one or two 26 10 AWG (0.13 - 5.3 mm 2 ) copper conductors. 1.3 These requirements do not apply to terminals for use wi

36、th aluminum conductors. 1.4 These requirements do not apply to multi-pole devices. Multi-pole devices are covered by UL 1977 and CSA C22.2 No. 182.3. 1.5 In Canada, general requirements applicable to this standard are given in CAN/CSA-C22.2 No. 0. 2 Denitions For the purpose of this standard the fol

37、lowing denitions apply. 2.1 BURR An extraneous protrusion in the stock, not considered an integral functional part of the connector or tab. 2.2 CONNECTOR (female connector) That portion of a quick-connect termination which is pushed onto the male tab. 2.3 C26000 ALLOY A copper-zinc alloy consisting

38、of approximately 70 percent copper and 30 percent zinc (cartridge brass) as specied by the Copper Development Associations Copper Development Alloy (CDA) Standards Handbook, Wrought Copper and Copper Alloy Mill Products, Part 2 Alloy Data. 2.4 DETENT A dimple (depression) or hole in the male tab tha

39、t engages a raised portion on the female connector, thus providing a latch for the mating parts. 2.5 PRODUCTION TAB (male tab) That portion of a quick-connect termination which receives the female connector. 2.6 QUICK-CONNECT TERMINATION An electrical connection consisting of a male tab and female c

40、onnector that can be readily inserted or withdrawn without the use of a tool. 2.7 REFERENCE POINT A specially marked point on a connector or tab that is used when making electrical test measurements. 2.8 TERMINAL An electrical connecting device; may be either a female connector or male tab. 2.9 TEST

41、 TAB (male test tab) A male tab, manufactured to close tolerances and with specic materials, used for the purpose of conducting tests with production female connectors.
