AS/NZS 3120:2011
Approval and test specification - Cord extension sockets
Sets out essential safety requirements for cord extension sockets and inlet plugs intended for use at extra-low or low voltages, and inlet plugs with rated voltages not exceeding 250 V and current ratings not exceeding 20 A in accordance with the pin configurations given in AS/NZS 3112. Does not apply to cord extension sockets that are enclosed within an appliance in such a way that they are not exposed to personal contact, or that are intended for use solely where they will be so enclosed.
