35、transfer panels, one of a series of Standards issued under Part II of the Canadian Electrical Code. This Standard incorporates the requirements of CSA Internationals Technical Information Letter No. M-03.Once published, provisions for automatic transfer switches and high voltage transfer switches wi
36、ll be covered in CSA C22.2 No. 178.1 and C22.2 No. 178.3, respectively.For general information on the Standards of the Canadian Electrical Code, Part II, see the Preface of CAN/CSA-C22.2 No. 0, General Requirements Canadian Electrical Code, Part II.This Standard was prepared by the Subcommittee on C

38、l Safety has provided the 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
39、 or construction, and when a relevant committee interpretation has not already been published, CSAs procedures for interpretation shall be followed to determine the intended safety principle”.January 2004Notes: (1) Use of the singular does not exclude the plural (and vice versa) when the sense allow
40、s.(2) 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 suitability for their particular purpose.(3) This publication was developed by consensus, which is defined by
41、CSA Policy governing standardization 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 no
42、t be in full agreement with all 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 C
43、anadian Standards Association, 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 surr
44、ounding the actual field condition; 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 governingstandardization and are published in CSAs periodical Info Update, which is available on

47、agreed-upon standards of quality, performance, interchangeability and/or safety, as appropriate. Where applicable, certification may form the basis for acceptance by inspection authorities responsible for enforcement of regulations. Where feasible, programs will be developed for additional products
48、for which certification is desired by producers, consumers, or other interests. In performing its functions in accordance with its objectives, CSA does not assume or undertake to discharge any responsibility of the manufacturer or any other party. The opinions and findings of the Association represe

Products that comply with this Standard shall not be certified if they are found to have additional features which are in
