AS/NZS 3112 is an Australian/New Zealand standard that specifies the requirements for plugs and socket-outlets for household and similar purposes. This standard outlines the design, dimensions, and safety requirements for electrical plugs and sockets used in Australia and New Zealand.
The plug and socket system is used for low voltage alternating current applications up to 250 volts and 10 amps. The plug has three flat pins arranged in a triangle, with the earth pin being larger than the other two pins to ensure it is engaged first. The socket has corresponding slots for the three pins, with the earth slot being wider than the other two slots to ensure correct insertion of the plug.
The AS/NZS 3112 standard specifies the dimensions, construction, and performance requirements for the plug and socket system. It also includes requirements for safety, such as insulation, creepage and clearance distances, and mechanical strength. The standard is regularly updated to ensure it meets the latest safety and performance requirements.
Key points about AS/NZS 3112 include:
Plug Types: The standard defines the configuration of the flat-pin plug commonly used in Australia and New Zealand, which typically has two flat pins in a V-shape and a grounding pin.
Voltage and Current Ratings: It specifies the voltage and current ratings for plugs and sockets, ensuring they are suitable for the electrical systems in these countries, typically 230V AC and up to 10A for standard plugs.
Safety Features: The standard includes requirements for safety features such as insulation, earthing, and protection against electric shock.
Testing and Compliance: Products must be tested to ensure they meet the standard's requirements, and compliance is necessary for legal sale and use in Australia and New Zealand.
Updates and Revisions: The standard is periodically reviewed and updated to incorporate new safety technologies and respond to changes in international standards.
For manufacturers and consumers, adherence to AS/NZS 3112 ensures that electrical products are safe and compatible with the electrical systems in Australia and New Zealand.
