39、ards issuedby CSA Group under Part II of the Canadian Electrical Code.This Standard replaces CSA TIL M-02A.Arc fault protective devices are usually embodied in combination with another device. As such, the userof this Standard will need to reference additional requirements as found in CSA C22.2 No.

40、5, CSA C22.2No. 144.1, CSA C22.2 No. 21, and CSA C22.2 No. 42 as applicable.For general information on the Standards of the Canadian Electrical Code, Part II, see the Preface ofCAN/CSA-C22.2 No. 0, General Requirements Canadian Electrical Code, Part II.This Standard is considered suitable for use fo

41、r conformity assessment within the stated scope of theStandard.This Standard was prepared by the Subcommittee on Arc Fault Protective Devices under the jurisdictionof the Technical Committee on Industrial Products and the Strategic Steering Committee onRequirements for Electrical Safety, and has bee

42、n formally approved by the Technical Committee.Interpretations: The Strategic Steering Committee on Requirements for Electrical Safety has providedthe following direction for the interpretation of standards under its jurisdiction: “The literal text shall beused in judging compliance of products with

43、 the safety requirements of this Standard. When the literaltext cannot be applied to the product, such as for new materials or construction, and when a relevantcommittee interpretation has not already been published, CSAs procedures for interpretation shall befollowed to determine the intended safet

44、y principle.”Notes:1) Use of the singular does not exclude the plural (and vice versa) when the sense allows.2) Although the intended primary application of this Standard is stated in its Scope, it is important to note that itremains the responsibility of the users of the Standard to judge its suita

45、bility for their particular purpose.3) This Standard was developed by consensus, which is defined by CSA Policy governing standardization Codeof good practice for standardization as “substantial agreement. Consensus implies much more than a simplemajority, but not necessarily unanimity”. It is consi

46、stent with this definition that a member may be included inthe Technical Committee list and yet not be in full agreement with all clauses of this Standard.4) To submit a request for interpretation of this Standard, please send the following information toinquiriescsagroup.org and include “Request fo

47、r interpretation” in the subject line:a) define the problem, making reference to the specific clause, and, where appropriate, include anillustrative sketch;b) provide an explanation of circumstances surrounding the actual field condition; andc) where possible, phrase the request in such a way that a

48、 specific “yes” or “no” answer will address theissue.Committee interpretations are processed in accordance with the CSA Directives and guidelines governingstandardization and are available on the Current Standards Activities page at standardsactivities.csa.ca.5) This Standard is subject to review fi

49、ve years from the date of publication. Suggestions for its improvement willbe referred to the appropriate committee. To submit a proposal for change, please send the followinginformation to inquiriescsagroup.org and include “Proposal for change” in the subject line:a) Standard designation (number);b) relevant clause, table, and/or figure number;c) wording of the proposed change; andd) rationale for the change.C22.2 No. 270-14Arc fault protective devicesDecember 2014 2014 CSA Group 8C22.2 No. 270-14Arc fault protective devices1 Scope1.1This Standard a
