37、 29-15Panelboards and enclosed panelboardsJanuary 2015 2015 CSA Group 7Preface This is the sixth edition of C22.2 No. 29, Panelboards and enclosed panelboards, one of a series of Standards issued by CSA Group under Part II of the Canadian Electrical Code. It supersedes the previous editions publishe
38、d in 2011, 1989, 1983, 1955, and 1936.In addition to incorporating minor edits and corrections to the previous edition, this new edition includes the requirements for:a) determining the accessibility of live parts by use of a finger probe;b) the integration of transfer switch equipment within a pane
39、lboard;c) clarification of neutral assembly requirements; andd) clarification of ampacity termination temperature markings.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
40、.This Standard is considered suitable for use for conformity assessment within the stated scope of the Standard.This Standard was prepared by the Subcommittee on Panelboards and Panelboard Enclosures under the jurisdiction of the Technical Committee on Industrial Products and the Strategic Steering
41、Committee on Requirements for Electrical Safety.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 it remains the responsibility of the use
42、rs of the Standard to judge its suitability for their particular purpose.3) This Standard was developed by consensus, which is defined by CSA Policy governing standardization Code of good practice for standardization as “substantial agreement. Consensus implies much more than a simple majority, but
43、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 all clauses of this Standard.4) To submit a request for interpretation of this Standard, please send the following information to inqu
44、iriescsagroup.org and include “Request for interpretation” in the subject line: 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 condition; andc) where possib
45、le, phrase the request in such a way that a specific “yes” or “no” answer will address the issue.Committee interpretations are processed in accordance with the CSA Directives and guidelines governing standardization and are available on the Current Standards Activities page at standardsactivities.cs
46、a.ca.5) This Standard is subject to review five years from the date of publication. Suggestions for its improvement will be referred to the appropriate committee. To submit a proposal for change, please send the following information to inquiriescsagroup.org and include “Proposal for change” in the
47、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. 29-15Panelboards and enclosed panelboardsJanuary 2015 2015 CSA Group 8C22.2 No. 29-15Panelboards and enclosed panelboards1 Scope1
48、.1 This Standard applies to panelboards and enclosed panelboards, rated 600 V and less, for use in nonhazardous locations in accordance with the Canadian Electrical Code, Part I, to provide overcurrent protection for a number of circuits.1.2 Clauses 1 to 6 apply to panelboards and enclosed panelboar
49、ds of other than the service entrance type and apply, unless otherwise noted, to the panelboards covered by Clauses 8 and 9 as follows:a) Clause 8 panelboards for service entrance use; andb) Clause 9 custom-built panelboard assemblies.1.3 This Standard covers the construction of the synthetic fuses to be used in the simulated load cycle test on fusible panelboards. (See Clause 10.)1.4 In this Standard, “shall” is used to express a requirement, i.e., a provision that the user is obliged to satisfy in order to comply with the standard; “shou
