Specifies essential safety requirements for plugs and socket-outlets for use in installation wiring systems for approval and test purposes. In Australia, This Standard is intended to be read in conjunction with AS 3100.

This Standard applies to plugs and socket-outlets having current ratings not exceeding 40 A, intended for indoor use, and at voltages not exceeding 500 V a.c., for the purpose of enabling connection and disconnection at will of the wiring system of an installation. Standardized configurations are given in Appendix A. This Standard also applies to plugs and socket-outlets used for removable partitions and for the connection of stationary equipment.This Standard does not apply to the following:(a) Appliance couplers for household and similar general purposes within the scope of AS 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 application within the scope of AS/NZS 3123.NOTES:This Standard may be applied to configurations and contact types other than those depicted herein providing all appropriate (to that type) requirements of this Standard are complied with.The deletion of Figures A1 to A12 is under consideration.
