scope:

This standard applies to two up to five wire installation couplers which includes earth (if provided) with a rated voltage up to and including 500 V a.c. and a rated connecting capacity up to and including 10 mm² for permanent connection in either indoor or outdoor electrical installations.
Installation couplers with additional contacts for voltages other than mains voltages are outside the scope of this standard.
Secretariat's note: during the examination of the document by the editing committee, it was noticed that all requirements for installation couplers with higher IP are included in the standard, see e.g. clauses 8, 10, 13, 14. Therefore the editing committee of TC23 decided to correct the scope accordingly. As a consequence, the editing committee decided to delete "for outdoor use, with higher IP ratings than IPX1" in note 4.
NOTE 1 Installation couplers according to this standard are used e.g. in prefabricated buildings, installation cavities, such as suspended floors and ceilings, or cable tray systems, cable ladder systems, cable ducting systems and cable trunking systems or in commercial show rooms, in partition walls and in any similar application or in furniture complying with IEC 60364-7-713.
NOTE 2 This standard may be used as a guide for installation couplers with additional contacts for voltages other than mains voltages.
An installation coupler consists of an installation female connector and an installation male connector for permanent connection not intended to be engaged or disengaged under load nor to be engaged or disengaged other than during first installation or during reconfiguration or maintenance of the wiring system in which installation couplers have been installed. This means that installation couplers are only intended for infrequent use.
Installation couplers shall not be used to replace socket-outlet systems. Installation couplers shall
not be used in place of devices for connecting luminaires (DCLs) according to IEC 61995 or luminaire supporting couplers (LSCs).
Installation couplers complying with this standard are suitable for use at ambient temperatures not normally exceeding + 40 ºC, but where the average temperature over a period of 24 h does not exceed +35 °C.
NOTE 3 For lower limits of in-service temperatures the necessary information is given in the manufacturer's installation instructions.
In locations where special conditions prevail, as in ships, vehicles and the like and in hazardous
locations, for example where explosions are liable to occur, special constructions may be required.
NOTE 4 Particular requirements for installation couplers e.g for. use at higher ambient temperatures, with higher mechanical durability (e.g. metal housings), with higher fire resistance,and for use in control circuits (e.g. SELV) , are under consideration.
NOTE 5 National rules may have requirements concerning the accessibility of installation couplers.
NOTE 6 Installation couplers are intended to be installed by instructed or skilled persons.
NOTE 7 National rules may specify who is allowed to carry out the connection and disconnection of installation couplers.
