This Standard applies to installation couplers with two- to five- poles with or without earthing contact and with a rated voltage up to and including 500 V a.c. and a rated current up to and including 32 A for permanent connection in indoor installation systems according to AS/NZS 3000. NOTE: Installation couplers according to this Standard are used in prefabricated houses, installation cavities (such as suspended floors and ceilings) cable trays and trunking, or in commercial show rooms, mobile or fixed stands at fairs or other exhibitions. They are also used in home and office furniture especially in office screens and partition walls. Installation couplers are a system which can replace connecting and junction boxes or other connecting devices and are intended for connection and disconnection without load. Installation couplers complying with this Standard are suitable for use at rated current in ambient temperatures not normally exceeding 25°C, but occasionally reaching 35°C. This Standard does not apply to the following: (a) Appliance couplers for household and similar general purposes within the scope of AS/NZS 3109.1. (b) Plugs and socket outlets within the scope of AS/NZS 3112.(c) Cord extension sockets within the scope of AS/NZS 3120.(d) Socket-outlet adaptors within the scope of AS/NZS 3122. (e) Plugs, socket-outlets and couplers for general industrial applications within the scope of AS/NZS 3123. NOTES: 1 This Standard may be used as a guide for installation couplers that fall outside of the scope of the Standard (e.g. for six-pole installation couplers, seven-pole installation couplers and installation couplers having a rated current greater than 32 A). 2 Installation couplers with additional contacts for voltages other than supply voltages are outside of the scope of this Standard, but the Standard may be used for the accessories involved, where applicable. 3 Guidance for the use of installation couplers is given in Appendix A. 4 Installation couplers are not intended to replace socket-outlet systems.
