Annotation

This Harmonization Document applies to residual current-operated devices (RCD) incorporated in, or specifically intended for use with two pole socket-outlets, with provision of earthing of the socket outlet for household and similar use (SRCD: socket-outlet residual current devices).

“SRCDs are only intended to provide supplementary protection downstream of the SRCD. SRCDs are intended for use in circuits where the fault protection and additional protection are already assured upstream of the SRCD.”

NOTE 1 Void.

NOTE 2 Void

NOTE 3 Void.

SRCDs are neither intended to provide an isolation function nor intended to be used in IT systems.

NOTE 4 For SRCDs intended to provide isolation or fault protection, or to be used in IT systems, IEC 61008-1 or IEC 61009-1 should be used, as applicable, in conjunction with the national requirements for socket outlets of the country where the product is placed on the market.

NOTE 5 Requirements and testing for SRCDs intended to be used in IT systems are under consideration.

SRCDs are not used in distribution boards. They are not intended for the protection of a complete distribution circuit or a complete final circuit. These products are intended to be installed

- in boxes in compliance with IEC 60670-1,

- or in cable trunking systems in compliance with the IEC 61084 series,
