This International Standard applies to residual current-operated devices (RCD) incorporated in, or specifically intended for use with two pole socket-outlets, with or without earthing contact 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 or phase to phase or phase to earthed middle conductor. SRCDs are only intended to provide additional protection downstream of the SRCD. SRCDs are intended for use in circuits where the fault protection (indirect contact protection) is already assured upstream of the SRCD. 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, - or in power track systems in compliance with the IEC 61534 series, - or in boxes according to one of the above standards adjacent to socket-outlet boxes. They are not intended to be used in enclosures or distribution boards in conformity with IEC 60670-24, IEC 61439-1 or IEC 60439-3. RCDs for household and similar use not covered by the scope of this standard are covered by IEC 61008-1 or IEC 61009-1. SRCDs energized from batteries, or a circuit other than the one powering the loads, are not covered by this standard. The residual current device incorporates the functions of detection of the residual current, of comparison of the value of this current with the residual operating value and of opening the protected circuit when the residual current exceeds this value. The maximum rated residual operating current is 30 mA. The maximum rated current is 16 A for devices with a rated voltage not exceeding 250 V a.c. or 20 A for devices with a rated voltage not exceeding 130 V a.c. This International Standard applies to SRCDs incorporating overload or overcurrent protection. This standard also applies to a connection unit incorporating a residual current device intended to protect only one piece of fixed electrical equipment immediately adjacent to the connection unit (e.g. hand dryer, water cooler, etc). The requirements of this standard apply for normal conditions of temperature and environment. Additional requirements may be necessary for devices used in locations having more severe environmental conditions. The socket-outlet part of an SRCD is covered by IEC 60884-1 or the national requirements of the country where the SRCD is placed on the market.
