BS 7288:2016 applies to residual current-operated devices (RCD)incorporated in, or specifically intended for use with, single pole and neutraland single pole and switched neutral and double pole socket-outlets, withprovision of earthing of the socket-outlet for household and similar uses (SRCD:socket-outlet residual current devices). SRCDs, according to this standard, areintended to be used in single phase systems such as phase to neutral. SRCDs areonly intended to provide supplementary protection downstream of the SRCD.SRCDs are intended for use in circuits where the fault protection and additionalprotection are already assured upstream of the SRCD.Cross References:BS 1362BS 1363BS 1363-2:2016BS 1363-4:2016BS 4662:2006+A1:2009BS 6004:2012BS EN 50525-2-11BS EN 60065BS EN 60529BS EN 60695-2-10:2013BS EN 60068-2-30:2005BS EN 60068-3-4 BS EN 61032:1998BS EN 61543:1996BS EN ISO 306CISPR 14-1 BS 7671BS EN 60112BS EN 60384-14BS EN 60664-1:2007BS EN 60664-3BS EN 60670-1BS EN 60670-24BS EN 60695-2-11:2014 BS EN 61008-1BS EN 61009-1BS EN 61084BS EN 61439-1BS EN 61439-3BS EN 61534BS EN ISO 2039-1BS EN ISO 2039-2BS IEC 60050-442:1998HD 62640IEC 62640:2011IEC 60050-426:2008 IEC 60050-441:2000IEC 60050-471:2007IEC 60417IEC 62640 Replaces BS 7288:1990 which remains current
