Introduction
GB 16916 and GB 16917 series of standards having one to four residual current electric poles suitable for installation in any part of the electrical device
Device. The collector may be mounted at the end of the entire electrical device into the line, the front end or one or more fixed electrical circuit means, or to a power supply
One or several outlets of the front end circuit. These appliances may be assembled with the receptacle in the same housing.
The RCD is possible to provide fault protection (indirect contact), additional protection (protection against direct contact) (if rated residual current is equal to
Or less than 30mA), and a fire hazard due to the fault current and the overcurrent protection is not provided due to the persistence of
protection. Satisfies GB GB 16917 or 16916 series of standards to ensure isolation of the RCD, and similar household can withstand high
The level of electromagnetic disturbances, and the electrical device can be used safely.
Although GB 16916 and GB 16917 series of standards applicable to the "combination in the socket of the RCD", but we know that due to the socket
The particular use and mounting portion, the boundary fixed electrical installations, close to the front end of the electrical device taken through the electrical plug into the socket, these
RCD requirements of different characteristics.
RCD socket usually installed by skilled or trained person can operate several times a day. Since it is considered the plug from the plug
Block has been pulled provide effective isolation, it does not require isolation. Outlet end of the RCD is not permanently connected and long wire has
Limit the number of electrical appliances to prove that it is reasonable to reduce the level of EMC. This standard includes the additional SRCD expected only for direct contact
protection. Taking into account these unique characteristics, it is necessary to draw up a SRCD standards.
Household and similar uses or without overcurrent protection
Residual current collector receptacle (SRCD)
1 Scope
This standard specifies the residual current collector comprises a function of detecting residual current, the residual current value and the residual operating current value is compared
Function, and a function when the residual current exceeds this value, the disconnection of the protected circuit.
Maximum rated residual current is 30mA.

Note 3. Technical requirements and test intended for use in IT systems SRCD under consideration.
SRCD distribution board should not be used, they are not a complete circuit of the terminal to protect the distribution circuit or complete. These products
Subject GB prospective mounting the mounting box 17466.1; or in compliance with GB/T 19215.1 cable trunking and ducting systems; or in compliance with IEC 61534
Supply piping system; or near the outlet box and meet one of the above standard installation box. These products are not intended for use in accord
GB 7251 GB 17466.24 or family housing.
RCD household and similar purposes not covered by this standard, including in GB 16916 or GB 16917. By a battery, or in addition to
The power to other load circuits other than the power SRCD not included within the scope of this standard.
This standard is also applicable to SRCD with overload or over-current protection.
This standard is also applicable to the assembly of a residual current wiring electrical components, the residual current collector is only used for a single wire assembly adjacent
Fixing electrical equipment (example. hand dryer, water coolers, etc.) to provide protection.
Note 4. SRCD designed to be operated by non-professional and does not require maintenance.
This standard applies to the technical requirements and environmental conditions of normal temperature. Used under more severe environmental conditions you may need to fill SRCD
Charge technical requirements.
