What You'll Learn
General Purpose Outlet
A General Purpose Outlet (GPO), also known as a General Power Outlet or power point, is a standard power outlet used in Australian homes. GPOs are electrical sockets that allow several appliances to be plugged into a single connector. They are designed to deliver optimal power to devices while minimising potential risks.
GPOs are defined as "a single or group of outlets provided on a distribution board, with each outlet being separately controlled by on off-only switching means, and all of which are supplied through the one input line" (AS3000 – Australian Standard for Wiring Rules). They are typically located in groups, often in venues such as hotels and airports for convenience.
GPOs come in various formats, including single, double, and quad sockets, as well as switched and unswitched outlets. Some even have USB charging built-in, which is convenient for trickle charging devices while keeping the power outlets free for other appliances.
It is important to note that all electrical work in Australia, including the installation of GPOs, must be completed by a licensed electrician. DIY work on GPOs is illegal and can be dangerous. Outdoor GPOs, in particular, must be installed with care to ensure safety. They should be weatherproof, have in-use covers to protect from rain, and be on a dedicated branch circuit to reduce the risk of electric shock.
The placement, circuit design, and protection of GPOs are key considerations in ensuring safety, convenience, and future readiness, especially when renovating or extending a home.

Socket outlet
In electrical terms, GPO stands for General Purpose Outlet. A GPO or power point refers to an electrical socket that allows several appliances to be plugged into one connector.
GPOs are at the forefront of modern electrical infrastructure, designed primarily for safety and efficiency. They provide a stable and secure power supply to a wide range of electrical appliances, delivering optimal power while minimising potential risks.
Double Power Points are a popular type of GPO, offering convenience and enhanced safety features. Unlike a regular double power point that disconnects only the active wire when switched off, double pole power points disconnect both the active and neutral wires, ensuring no electrical leakage or shock hazard when appliances are not in use.
There are various types of electrical sockets available, each designed to meet specific needs. For example, a rotating outlet can rotate 360 degrees, making it useful in tight spaces and for accommodating large plugs. Universal Serial Bus (USB) outlets are a type of combination electrical socket that contains both a standard two-prong plug and a USB charging port. These outlets are convenient, save space, and are available in USB and USB Type-C port options.
For safety, it is recommended to use Arc Fault Circuit Interrupter (AFCI) outlets to prevent electrical fires. Ground Fault Circuit Interrupter (GFCI) outlets are also essential in areas that could be exposed to water or moisture, as they protect against electrical shocks and automatically shut off power when necessary.

Power point
GPOs are commonly used in the United Kingdom, Australia, New Zealand, and other countries with a three-pin electrical system. In Australia, the standard mounting height for GPOs in living rooms and bedrooms is at least 75mm from the finished floor level, ensuring accessibility and reducing the chance of water or dust ingress. Outdoor GPOs must be weatherproof and rated IP67 or higher, with in-use covers to protect plugs from rain.
GPOs come in various formats, including single, double, and quad sockets, as well as switched and unswitched options. Some modern GPOs even include USB charging ports, providing added convenience for device charging while keeping power outlets available for other appliances.
It is important to note that all electrical work involving GPOs must be completed by a licensed electrician. DIY work on GPOs is illegal and can be dangerous. Regular inspections and upgrades are recommended to ensure safety and compliance, especially in older homes.
With the increasing reliance on electronic devices, power points have become essential in facilitating their use. GPOs are designed to provide a stable and secure power supply, delivering optimal power to devices while prioritising safety and efficiency.

Double power points
GPO stands for General Purpose Outlet, a term commonly used to refer to an electrical outlet, be it a single or double power point.
While double power points offer convenience, safety can sometimes be a concern, especially in high-demand electrical environments. This is where the Double Pole Power Point comes into play. Unlike a regular double power point that disconnects only the active wire when switched off, a double pole power point disconnects both the active and neutral wires, ensuring no electrical leakage or shock hazard when appliances are not in use.

Safety and efficiency
GPO stands for General Purpose Outlet, also referred to as a General Power Outlet. It is an electrical socket that allows several appliances to be plugged into one connector. These outlets are designed primarily for safety and efficiency, providing a stable and secure power supply to a wide range of electrical appliances.
GPOs are designed to deliver optimal power to devices while minimising potential risks. They are tailored to suit the general power requirements of various devices, with specifications like voltage and current ratings customised to match the needs of different appliances. This ensures a safe and efficient power supply, reducing the risk of electrical issues.
The double GPO, for example, offers two power outlets on a single plate, allowing multiple devices to be powered from a single location. This enhances space efficiency by reducing the need for excessive wiring and maximising available space. It also improves safety by providing a more organised setup, reducing the reliance on extension cords and double adapters, which can pose safety hazards, especially with high-powered appliances.
In certain high-demand electrical environments, double power points may raise safety concerns. In such cases, a Double Pole Power Point can be employed. Unlike standard power points, which disconnect only the active wire when switched off, the Double Pole Power Point disconnects both the active and neutral wires, ensuring complete isolation of the appliance from the power source and enhancing safety by preventing electrical leakage or shock hazards.
Additionally, for heavy or fixed appliances like dishwashers or washing machines, a fused spur can be used to create a new circuit with its own protective fuse. This provides individual control and protection for each appliance, further enhancing the safety and efficiency of the electrical setup.
