Specifies essential safety requirements for plugs, socket-outlets, cable couplers and appliance couplers for operation at 50Hz, with a rated voltage not exceeding 660V and a rated current not exceeding 315A intended for general industrial use. It is intended to be read in conjunction with AS/NZS3100.

This Standard sets out the requirements for plugs and socket-outlets, cable couplers and appliance couplers for operation at 50 Hz, with a rated voltage not exceeding 660 V and a rated current not exceeding 315 A, primarily intended for general industrial use, either indoors or outdoors.This Standard applies to plugs and socket-outlets, cable couplers and appliance couplers (referred to in this Standard as 'accessories') for use when the ambient temperature does not normally exceed 40°C.The use of accessories (see Note 1) in building sites and in agricultural, commercial and domestic situations is not precluded.Appliance inlets incorporated in, or fixed to, electrical equipment are within the scope of this Standard.This Standard does not apply to accessories that comply with AS/NZS 60320.1 and AS/NZS 3112 and which are primarily intended for domestic and similar general purposes, nor to accessories that comply with AS 2380.1 and are intended for explosive atmospheres.The configurations shown in this Standard depict standardized Australian and New Zealand industrial plugs, socket-outlets, cable couplers and appliance couplers for operation at 50 Hz.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.Devices that comply with IEC 60309-1 are deemed to comply with the appropriate requirements of this Standard.
