Introduction
Residual current devices are primarily intended to give protection against the risk of dangerous, and possibly lethal, electric shocks and to provide protection against fire hazards due to a persistent earth fault current.
This standard specifies the operational characteristics for these devices; details of how they should be installed to provide the desired level of protection are specified in the various parts of GB 16895.
This standard is intended for use by technical committees and relevant organizations in the preparation of standards for residual current devices. It is not intended to be used as a stand-alone standard, for example, for certification.
It has been prepared in accordance with its pilot function for residual current devices.
There are two basic conditions of protection against the risk of electric shock: fault protection (indirect contact) and basic protection (direct contact).
Fault protection implies that the device is used to prevent dangerous voltages persisting on accessible installation metalwork, which are earthed but become live under earth fault conditions.
Under such conditions, the risk arises not from the user making direct contact with a live conductive part but from making contact with earthed metalwork, which itself is in contact with a live conductive part.
The primary or basic function of residual current devices is to give fault protection, but, with devices of adequate sensitivity (i.e., units having operating residual currents not exceeding 30 mA), there is the additional benefit that, should other methods of protection fail, the device will give a high degree of protection to a user making direct contact with a live conductive part.
The operating characteristics given in this standard are therefore based on requirements, which themselves are based on the information contained in GB/T 13870 Effects of Current on Human Beings and Livestock.
These devices also provide protection against the risk of fire resulting from earth fault currents which can persist for lengthy periods without operating the overcurrent protective device.
General Requirements for Residual Current Operated Protective Devices
1 Scope
The requirements of this standard apply to residual current operated protective devices (hereinafter referred to as “residual current devices” (RCD)) for rated voltages not exceeding 440 V a.c., intended primarily for protection against shock hazard. They are intended to be used by technical committees and relevant organizations when drafting product standards and apply only if they are incorporated or are referred to in the relevant standards. This standard is not intended to be used as a stand-alone standard, for example, for certification.
Note 1: This standard may also be used as a guide for residual current devices of rated voltages up to 1 200 V, a.c., the performance of which shall be determined through negotiation between the manufacturer and the user when the standard for relevant products are prepared.
It applies to
——a single device which detects a residual current (see 3.3.2), compares it to a reference value (see 3.3.3) and opens the protected circuit when the residual current exceeds this reference value (see 3.3.4);
——an association of devices, each one of them performing separately one or two of the above-mentioned functions, but acting together in order to accomplish all three functions. Particular requirements may be necessary for devices intended for accomplishing only one or two of the above three functions.
Any standard for accessories, devices or equipment capable of completing only one or two of the above-mentioned three functions or failing to fully comply with all parts of this standard cannot be referred to as RCD standard, or refer to "RCD", either abbreviation or full name "residual current device". "RCD" shall not be marked on products of such accessories, devices or equipment or in their technical documents.
This standard applies for conditions as stated in Chapter 7. For other conditions, additional requirements may be necessary.
Residual current devices are intended to protect persons and livestock against harmful effects of electric shock due to contact with exposed conductive parts by automatic disconnection of supply in accordance with GB/T 17045-2008 and GB/T 16895.21-2011.
Note 2: In this context “harmful effects” include the risk of occurrence of heart fibrillation.
In accordance with GB/T 16895.4-1997, residual current devices with a rated residual operating current not exceeding 300 mA may also be used to provide protection against fire hazards due to a persistent earth fault current.
In accordance with GB/T 16895.21-2011, residual current devices with a rated residual operating current not exceeding 30 mA may also be used for additional protection in case of failure of the basic protective provisions or carelessness of the user of the installation or equipment.
For residual current devices performing additional functions, this standard applies together with the relevant standard covering the additional functions; for example, when residual current devices incorporate a circuit-breaker it should comply with the relevant circuit-breaker standard.
Supplementary or particular requirements may be necessary, for example, for
——residual current devices intended for use by uninstructed persons;
——socket-outlets, plugs, adapters and couplers incorporating residual current devices.
This standard states
——the definitions and terms used for residual current devices (Chapter 3) ;
——the classification of residual current devices (Chapter 4);
——the characteristics of residual current devices (Chapter 5);
——the preferred values of the operating and influencing quantities (5.4);
——the marking and information to be provided for residual current devices (Chapter 6);
——the standard conditions for installation and operation in service (Chapter 7);
——the requirements for construction and operation (Chapter 8);
——the list of minimum requirements to be tested (Chapter 9).
Note 3: Devices having a residual current function for specific purposes other than those mentioned above (for example, motor protection) are not covered by this standard.
