Australian 3-Pin Electrical
Mains Plug
The domestic mains power supply in
Australia is 240V AC, 50Hz. Standard 3-pin earthed power outlets are rated
at 10Amps and are usually switched. The 3-flat-pin plug is used in all
states of Australia (including its external territories), New Zealand, Papua
New Guinea and the Solomon Islands. Although the configuration is similar
to mains plugs used in mainland China, dimensional differences to the plug
body may be incompatible with recessed cord socket and prevent
Chinese-compliant CPCS/CCC (CCEE) plugs from being legally sold/used in
Australia. Argentina also uses a similar 3-flat-pin configuration as
Australia, but with slight dimensional differences and with the active and
neutral wires being reversed. These important differences prevent the
Argentina-compliant IRAM plugs from being legally sold/used in Australia as
incorrect polarity may present an electrical safety hazard.
The Australian mains plug configuration was
originally presented as provisional standard C112 in 1937, formalised as
Standard C112 in 1938, redesignated AS3112 in 1981 and harmonized with
the New Zealand standard and redesignated AS/NZS3112 in 1993. Australian
Standards AS/NZS 3112:2000 and AS/NZS3112:2004 for Australian Mains Plugs
now define the requirements for the
insulation
of the Active and Neutral pins of the plug.
15Amp and 20Amp configurations
of the mains plug and outlet are also defined by the standard.
The following diagram shows the Australian plug
wiring configuration.
The diagrams below show wiring for an
Australian 240V mains cord plug and socket. Note the "reversal" of the Active
and Neutral wires depending on whether you are wiring a socket or a plug.
