EV Charger Installation Requirements Australia

In this blog, we cover the EV charger installation requirements in Australia from a legal perspective and an installation perspective. Read on to make sure you tick all the boxes for a safe and compliant electric vehicle charging station that is correctly designed and installed for your location, your electrical system and your needs. 

What are the EV charger installation requirements in Australia?

EV charger installation requirements in Australia fall under the Australian Standards for electrical installations called the Australian and New Zealand Wiring Rules, AS/NZS 3000:2018. Under these Standards there are mandatory requirements relevant to EV charger installation. Each installation must:

  • Be completed by a fully-qualified, licensed electrician
  • Be connected to mains power (hard-wired)
  • Include a dedicated circuit for each charger unit, with no other appliances wired from the same circuit
  • Include an individual overcurrent protective device for each charger unit (circuit breaker)
  • Be fitted with RCD protection (Residual Current Device)
  • Be 800mm from the ground (minimum height)
  • Be installed with a correctly-sized cable for the required load

Electrical cable sizing falls under Australian Standard, AS/NZS 3008.1.1:2017

State and local regulations for EV charger installation requirements in Australia

State and local regulations also apply for EV charger installations such as building codes and energy efficiency requirements, particularly for commercial buildings or multi-dwelling units. These can vary based on the location, size and specifics of the installation. 

Your installer may also need to notify or seek approval from your distribution network service provider (DNSP) prior to installation. Specific requirements or procedures for connecting your EV charger to the grid may apply, depending on the capacity of the charger.

Legally you must use a fully qualified, licenced electrician

An EV charger is a hard-wired appliance. By law and under EV charger installation requirements in Australia, only a fully-qualified licensed electrician is permitted to install an EV charging station. Licenced electricians in Australia are required to comply with the Australian Standard AS/NZS 3000 and the Electricity Safety Act 1998. This ensures the safety, compliance and integrity of your installation.

The EV charger: installation requirements in Australia

The EV charger appliance itself must comply with:

Choosing an experienced installer with an intimate knowledge of modern EV charger brands and installation layouts will also ensure that your installation is correctly installed to manufacturer guidelines, preserving your warranty.

Power supply to the EV charger 

Your EV charger is a hard-wired appliance, meaning it draws energy directly from mains power, through your switchboard. Your installer should assess the capacity of your existing electrical infrastructure and undertake the necessary upgrades for a compliant installation to ensure it can safely handle the additional load. Each EV charging station should have:

  • A dedicated circuit 
  • No other appliances wired from the same circuit (such as washing machines and dryers)
  • An overcurrent protective device (circuit breaker)
  • RCD protection (Residual Current Device)
  • The correctly-sized cable for the required load

Minor switchboard upgrades may be required to support the new appliance and maintain compliance with AS/NZS 3000

Overcurrent protection and EV charger installation requirements Australia

Overcurrent protection (a circuit breaker) protects the circuit supplying the EV charger against overload by breaking the circuit if too much electricity flows through the cable. This prevents overheating and cable damage, which is a critical safety hazard. The manufacturer instructions provide the current level and trip curve specifics to determine a suitable circuit breaker for the installation. The overcurrent protective device must comply with AS/NZS 60898, AS/NZS 61009 or AS/NZS 60947.

RCD protection and EV charger installation requirements Australia

An RCD (Residual Current Device) is a safety mechanism that breaks the electrical circuit when the current travelling between the EV charger and the EV becomes unbalanced. The RCD protects against infrastructure damage and electric shock by preventing an unbalanced residual current flowing through the body of the EV (or a person) to the floor or ground. RCD’s (also known as safety switches) are required for all domestic wiring and must be incorporated into every EV charger installation.

Your Solstra technician will determine the type of RCD required for your specific installation (Type A, B or C), ensuring that all standards and safety regulations are met.

Cable sizing for EV charger installation requirements in Australia

Cable sizing from the power supply to the EV charger is installed in accordance with AS/NZS 3008.1.1:2017 (the same standard that electricians use to size any cable). To determine the appropriate cable sizing appropriate for your installation, your installer will consider:

  • The current that the cable needs to support
  • The distance the cable needs to run to support the appliance
  • The installation environment.

The capacity (diameter) of the cable is also important for safety reasons. If the cable is undersized, it will overheat and there is a risk of it burning. When determining the appropriate cable size for your charging station, Solstra will also consider factors such as the electrical current available, charging power required, the charging cable length that is required for your setup and environmental temperatures.

Safe and protected use

Should be installed in an environment where they are protected from mechanical and environmental damage and can be used safely. They should also be installed according to manufacturer instructions by a fully-qualified licensed electrician, preserving your warranty and optimising the longevity for your investment. 

Important safety considerations in terms of positioning for your EV charger include:

  • Accessibility: An accessible location with no impact to outside activity or other traffic
  • Reach: The cable must be able to reach the charge port comfortably, without pulling or tugging
  • Breathing room: Adequate space surrounding the charger (i.e. when wall-mounted)
  • Weatherproof: Only outdoor-rated units should be selected for outdoor installations
  • Protected from knocks: Distance from potential obstructions and falling or protruding objects

EV charger installation requirements in Australia specify that EV chargers are to be installed at least 800mm from the ground, as a minimum height requirement. EV chargers installed outside ideally should have an IP rating (Ingress Protection Rating) of IP44 or higher.

Cable length

There are many quality EV charger brands on the market with varying cable lengths, including 3 metre, 5 metre and even 10 metre charge cables. From a safety perspective, it’s important to note that the longer the cable, the heavier it becomes. To put this in perspective, a 5-metre cable will weigh around 3 kg and 10-metre cable will weigh roughly 6 kg. Cable length will also determine how flexible your parking options are in terms of angle and front on (vs. reverse).

The suitability of a longer cable is determined by the environment and the user needs. At Solstra we offer site assessments as well as quality advice on the best EV charger and installation setup to suit your needs, while addressing all EV charger installation requirements in Australia.
