34、/CSA-C22.2 No. 0, General Requirements Canadian Electrical Code, Part II.This Standard is considered suitable for use for conformity assessmentwithin the stated scope of theStandard.This Standard was prepared by the Subcommittee on Meter-Mounting Devices under the jurisdiction ofthe Technical Commit

35、tee on Industrial Products and the Strategic Steering Committee on Requirementsfor Electrical Safety.Interpretations: The Strategic Steering Committee on Requirements for Electrical Safety has provided thefollowing direction for the interpretation of standards under its jurisdiction:“Theliteral text

36、 shall be usedin judging compliance of products with the safety requirements of this Standard. When the literal textcannot 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 interpretat

37、ion shall befollowed to determine the intended safety 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 responsibi

38、lity of the user of the Standard to judge its suitability for his 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 simplemajo

39、rity, but not necessarily unanimity”. It is consistent 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 informatio

40、n toinquiriescsagroup.org and include “Request for 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

41、possible, phrase the request in such a way that a 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 standardsactivitie

42、s.csa.ca.5) This Standard is subject to review five years from the date of publication and suggestions for its improvementwill be referred to the appropriate committee. To submit a proposal for change, please send the followinginformation to inquiriescsagroup.org and include “Proposal for change” in

44、. 115-14Meter-mountingdevices1 Scope1.1This Standard applies to indoor and outdoor meter-mounting devices, either as complete self-containeddevices or provided as a part of service equipment, for use in nonhazardous locations, and intended tobe employed in accordance with the Rules of the Canadian E

45、lectrical Code, Part I (“CEC Part I”).1.2This Standard covers devices for use with watt hour meters, demand meters, time switches, currenttransformers, test switches, instruments, and similar devices rated at 320 A or less per meter socket, 600V or less, single or polyphase,and multiple-positionmete

46、r socket assemblieswith an overall currentrating of 600 A or less (200 A maximum per meter socket).1.3This Standard applies to subfeed meter-mounting devices that have provision for the main loadterminations and for one subfeed termination.1.4This Standard applies to the meter-mounting device portio

47、n when supplied as a part of service or otherequipment where applicable.1.5Meter-mounting devices, as covered by this Standard, are not intended to be used as load-making orload-breakingdevices.1.6This Standard applies to transformer-rated meter-mounting devices that consist of current transformers,

48、meter sockets, and optional test switches, mounted in the same enclosure rated 600 A or less and 600 V(nominal) or less.1.7In this Standard,“shall” is used to express a requirement, i.e., a provision that the user is obliged tosatisfy in order to comply with the standard; “should” is used to express

49、 a recommendation or thatwhich is advised but not required; and “may” is used to express an option or that which is permissiblewithin the limits of the standard.Notes accompanying clauses do not include requirements or alternative requirements; the purpose of anote accompanying a clause is to separate from the text explanatory or informative material.Notes to tables and figures are considered part of the table or figure and may be written asrequirements.C22.2 No. 115-14Meter-mounting devicesJuly 2014 2014 CSA Group 9Annexes are designated normativ
