1 Scope This British Standard applies to residual current -operated devices ( RCD ) incorporated in, or specifically intended for use with, single pole and neutral and single pole and switched neutral and double pole socket-outlets, with provision of earthing of the socket-outlet for household and similar uses (SRCD: socket-outlet residual current devices). SRCDs, according to this standard, are intended to be used in single phase systems such as phase to neutral. 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, BS EN 61008‑1 or BS EN 61009‑1 should be used, as applicable, in conjunction with the requirements of BS 1363‑2 for socket-outlets.
