Each charger also needs a dedicated circuit with its own overcurrent protective device and RCD protection.
These requirements might sound technical, but here’s the simple explanation: they ensure your charging setup works reliably while keeping potential hazards at bay.
What’s changing in Australian EV infrastructure? Recent updates to the National Construction Code now require new apartment buildings to be built “EV-ready”. This forward-thinking approach tackles one of the biggest barriers to EV adoption: charging infrastructure availability.
The big question you’ll need to answer is: Are you prepared to make the right decisions about your EV charging setup today? Understanding these standards puts you ahead of the curve and keeps safety as your top priority.
Why EV Charger Safety Standards Matter
Safety standards for EV chargers serve as the foundation for secure electric vehicle charging across Australia. These regulations aren’t bureaucratic red tape; they address genuine risks that come with high-voltage electrical equipment operating daily in homes and businesses.
Protecting people and property
EV charging involves substantial electrical power, creating risks that need careful management. Residual current devices (RCDs), commonly known as safety switches, deliver essential protection against electric shocks by instantly cutting power when they detect current imbalances. These devices protect not just EV owners handling charging equipment, but also children and others who might accidentally contact damaged components.
Fire safety considerations matter equally, especially in shared buildings. Electric vehicles are generally more fire-safe than petrol cars, but proper safety measures remain crucial. Property owners need to ensure charging bays maintain adequate spacing to prevent potential fires from spreading, particularly in apartment buildings where multiple vehicles may be charging at once.
Avoiding electrical hazards
Electric vehicles operate at much higher voltages than other battery-powered equipment, creating unique safety risks. Without proper safeguards, these systems could expose users to:
- Electric shock risks from faulty components
- Fire hazards from overheating or short circuits
- Exposure to toxic gases or battery electrolytes if damaged
Overcurrent protection devices like circuit breakers provide another critical safety layer by protecting against overloads and short circuits. Installation requirements often include mechanical protection methods, such as bollards, in locations where vehicles are moving nearby.
Supporting long-term EV adoption
Well-designed safety standards directly support broader EV adoption by building public confidence in charging infrastructure. One major barrier to EV adoption has been uncertainty about charging infrastructure availability and safety.
Clear guidelines for EV charger installation and operation help create a user-friendly and secure charging network both at home and in public spaces. This encourages more drivers to make the transition to electric vehicles.
These standards also ensure the longevity and reliability of charging equipment. Users can trust that public and private charging solutions will function properly and safely throughout their vehicle’s lifetime, a crucial factor for long-term EV ownership confidence.
Installation Standards You Must Follow
Getting your EV wall charger installed correctly means following specific Australian safety standards that protect both your family and property. These aren’t just recommendations; they’re mandatory requirements that ensure your charging setup operates safely and efficiently.
Dedicated circuits and no shared loads
AS/NZS 3000:2018 (section P3) makes this crystal clear: each EV charger must have its own dedicated circuit. No sharing with washing machines, dryers, or any other appliances. The Electric Vehicle Council (EVC) confirms that while some charging stations support multiple connection points, the entire unit still needs its own dedicated circuit.
Why does this matter? Dedicated circuits prevent overloading and guarantee consistent power delivery to your vehicle, exactly what you need for reliable charging night after night.
Circuit breakers and overcurrent protection
Every EV charger installation requires an appropriate circuit breaker to protect against overload and short circuits. Think of circuit breakers as your first line of defence. They automatically cut electricity flow when excessive current is detected, preventing cable damage and overheating.
Your electrician should install circuit breakers with the appropriate “C” tripping characteristic specifically designed for EV charging stations. The manufacturer’s instructions will specify the exact current level and trip curve needed for your particular charging unit.
RCDs and shock prevention
Residual Current Devices (RCDs) provide critical protection against electric shock by instantly breaking the circuit when current imbalances occur. For EV chargers, you’ll need one of these options:
- Type A RCD: Acceptable only if your charger has built-in DC fault current protection
- Type B RCD: Required if your charger lacks DC fault protection above 6mA
Important note: The RCD must disconnect all live conductors, including the neutral, making single-pole RCBOs unsuitable for this application.
Minimum height and accessibility
Australian requirements specify that EV chargers must be installed at least 800mm off the ground. This minimum height ensures accessibility while protecting the unit from damage. Consider cable reach, surrounding space, and weather protection for outdoor installations.

What Makes EV Charging Equipment Compliant
Selecting compliant EV charging equipment protects both your vehicle and property, but navigating Australian compliance standards doesn’t have to be complicated.
AS/NZS 3820 and EESS explained
The Australian and New Zealand Standard AS/NZS 3820 sets essential safety requirements for all electrical equipment. This standard works alongside the Electrical Equipment Safety System (EESS), a regulatory framework designed to increase consumer safety for household electrical equipment. Together, they ensure EV charging equipment meets strict safety criteria before reaching the market.
Here’s what to look for: EV charging equipment compliance often involves adherence to specific standards, including IEC 61851 (for conductive charging systems) and IEC 62196 (for plugs and connectors). The Regulatory Compliance Mark (RCM) on any charger indicates the product has met Australian safety requirements.
Choosing the right EV wall charger
Safety features should be your primary concern when selecting an EV wall charger. Quality chargers include built-in protections against overheating, short circuits, and power surges.
