GB /Z22721-2008/IEC /TR62350..2006IntroductionThe purpose of this guidance document is to provide designers, manufacturers, and installers with a view to optimizing the long-term availability of protection provided by the RCD As well as users and guides and information for maintenance personnel responsible for the selection, installation and use of RCDs in fixed electrical installations. In the last 40 years, the IEC Technical Committee (inter alia, within SC23E) has compared and used the data collected by manufacturers, laboratories, installers, The experience accumulated by users and installers, the IEC has made progress on RCD reliability by revising the RCD standard. Around this goal Standard, the technical requirements and tests of these IEC standards have been added and improved. When SC23E decided to introduce such as analog RCD aging 28 days environmental testing and other technical requirements, it has made considerable progress. The user, installer, and other committees of the IEC are required to inform the IEC that while compared to the earlier RCD, while meeting the relevant RCD standards RCD reliability has been substantially improved, but the availability of protection provided by RCDs is related to many parameters, not only with the RCD itself Off, but also with the installation and use of the environment. This guidance document comprehensively identifies and describes the main factors affecting the availability of RCD protection in order to further promote RCD Operate reliably and enhance the valuable protection provided by this appliance. In order to implement this step by step through the publication of the technical guide The work already done by the SC23E will continue to monitor this important area (reliability). Additional Information. During the meeting between TC64 and SC23E officials, confirm that this Guidance Document does not conflict with the TC64 standard There are contradictions, and the purpose of this guidance document is to provide information for better understanding and proper use of the RCD. GB /Z22721-2008/IEC /TR62350..2006 Correct use of household and similar use of residual current action Guide to Protective Electrical Appliances (RCDs)1 ScopeThis technical note provides the residual current operated protective device (RCD) provided by the national standard for household and similar purposes A summary of the availability of protection. This guidance document highlights key parameters that affect the availability of protection and provides guidance on Information on how to install and use the RCD and the environmental conditions after installation. This Guidance Document gives information on the availability of protection in fixed electrical installations and how high (during installation and maintenance) General information about the level of protection availability available; the development of this technical guidance document is useful to all standardization technical committees, installers, inspections And users. Note 1. The term RCD is a general purpose family of products that can be automatically switched off when the residual current equals or exceeds the rated residual operating current IΔn of the RCD the term. This general term applies generally to. RCCB --- residual current circuit breaker without over-current protection; RCBO --- residual current circuit breaker with overcurrent protection; SRCD --- outlet residual current electrical appliances; PRCD --- mobile residual current appliances. The difference between RCCB and RCBO is that RCBO has added over-current protection function, while RCCB has no protection against over-current. NOTE 2 PRCDs are not considered part of a fixed electrical installation and are therefore not covered by this technical document.2 Normative referencesThe following documents contain provisions which, through reference in this Guidance Document, become the provisions of this Guidance Note document.
