33、onvi July 2010PrefaceThis is the first edition of C22.2 No. 0.19, Requirements for service entrance equipment. This Standard gives the general and specific minimum safety objectives that service entrance equipment must meet.This Standard also illustrates specific prescriptive solutions that meet the

34、 safety objectives.For general information on the Standards of the Canadian Electrical Code, Part II, see the Preface of CSA C22.2 No. 0, General Requirements Canadian Electrical Code, Part II.This Standard was prepared by the Subcommittee on Requirements for Service Entrance Equipment, under the ju

35、risdiction of the Technical Committee on Industrial Products and the Strategic Steering Committee on Requirements for Electrical Safety, and has been formally approved by the Technical Committee.Interpretations: The Strategic Steering Committee on Requirements for Electrical Safety has provided the

36、following direction for the interpretation of standards under its jurisdiction: “The literal text shall be used in judging compliance of products with the safety requirements of this Standard. When the literal text cannot be applied to the product, such as for new materials or construction, and when

37、 a relevant committee interpretation has not already been published, CSAs procedures for interpretation shall be followed to determine the intended safety principle.”July 2010Notes: (1) Use of the singular does not exclude the plural (and vice versa) when the sense allows.(2) Although the intended p

38、rimary 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.(3) This publication was developed by consensus, which is defined by CSA Policy governing standard

39、ization Code of good practice for standardization as “substantial agreement. Consensus implies much more than a simple majority, but not necessarily unanimity”. It is consistent with this definition that a member may be included in the Technical Committee list and yet not be in full agreement with a

40、ll clauses of this publication.(4) CSA Standards are subject to periodic review, and suggestions for their improvement will be referred to the appropriate committee.(5) All enquiries regarding this Standard, including requests for interpretation, should be addressed to Canadian Standards Association

41、, 5060 Spectrum Way, Suite 100, Mississauga, Ontario, Canada L4W 5N6. Requests for interpretation should(a) define the problem, making reference to the specific clause, and, where appropriate, include an illustrative sketch;(b) provide an explanation of circumstances surrounding the actual field con

42、dition; and(c) be phrased where possible to permit a specific “yes” or “no” answer.Committee interpretations are processed in accordance with the CSA Directives and guidelines governing standardization and are published in CSAs periodical Info Update, which is available on the CSA Web site at www.cs
