EV Charger Safety Rules in QLD: What Homeowners Must Know Before Installing

The Rise of Electric Vehicles 

Many are making shifts to electric vehicles (EVs) here in Sunshine Coast making a significant increase in the demand for safe and standards-compliant EV charger installation. Having an EV charger installation is a crucial electrical decision since it’s not simply as plugging a new appliance. There must be strict compliance with Queensland and Australian standards to ensure safety and efficiency as it involves a high-power system.

The EV charging here in Queensland is governed by the national electrical safety standards, the National Construction Code (NCC), and local grid connection rules. The set of rules plays a significant role in protecting every business against possible electrical overloads, shock hazards or even the risk of fire. 

Here in Axon Electrical, we assist you in installing your EV charger while we ensure compliance with the latest Queensland specific standards. This includes the installation of a Type B Residual Current Device (RCD), which is an important component that is often lacking in standard residential electrical systems.

What is the Key Electrical and Safety Requirements?

Make sure to comply with the following as you plan to install an EV charger here in Queensland:

1. Hire a Professional

A fully licensed electrician must handle the installation of EV chargers that are in compliance with AS/NZS 3000:2018 Wiring Rules and the Electricity Safety Act 1998.

2. Design a Dedicated Circuit

There should be a dedicated circuit for every EV charger that is connected straight to the switchboard. Take note that no other appliances should be allowed to share with this circuit.

3. Essential Protection Devices

These are the safety components for every charger installation:

• An individual overcurrent protection device (circuit breaker)

• A Residual Current Device (RCD), specifically a Type B RCD, which is required to detect both AC and DC leakage currents commonly linked to EV chargers.

4. Product Compliance

It is important that the EV charger must meet the requirements of both AS/NZS 3820 and the Electrical Equipment Safety System (EESS) framework.

5. Mechanical and Environmental Safety Requirements

If the charger is installed in the outdoor or located in commercial areas, the following standards should be complied with:

• Impact Protection: Must have protection from vehicle impact (e.g., via bollards)

• Weather Resistance (IP Rating): A minimum ingress protection rating of IP44 should be needed for resistance to water and dust.

• External Impact Resistance (IK Rating): A minimum external mechanical impact rating of IK07 must be achieved.

• Installation Height: The charger must be mounted at a minimum height of 800mm above ground level.

  
  

The Special Device Queensland Requires — Type B RCD

The Type B RCD is a crucial element yet often overlooked in EV charger installation. Compared to standard RCDs (Type A or AC) which only detect alternating current (AC) faults, EV chargers can generate direct current (DC) leakage. If this DC leakage happens, it is possible that a standard RCD will fail to trip, which will cause electrical dangers.

This is the reason why there is a mandate from Queensland's electrical code for all EV charging circuits to comply with a Type B RCD. In this setup, a Type B RCD can detect both AC and DC leakage, guaranteeing an immediate shutdown of the charger in the event of a fault.

At Axon Electrical, our EV charger installation will ensure compliance with standards and safety features:

• A Type B RCD will be installed that meets Australian safety standards.

• A dedicated circuit protected by a correctly rated circuit breaker.

• Comprehensive testing and certification to ensure the entire setup successfully passes inspection.

To safeguard your property and also the onboard electronics of your electric vehicle, this safety protection is absolutely necessary and mandated legally.

Queensland-Specific Grid Connection Rules

The Queensland Electrical Connection Manual (QECM, version 4) has created rules to help manage growing Electric Vehicle (EV) demand on the grid. Homeowners should comply with the following: 

• Standard Charger Limit (20 Amp / 4.6 kW)

  A single-phase EV charger connected to a standard, continuously available circuit is limited to a maximum of 20 amps continuous current.

  
  

• Requirements for Higher Output Chargers (32 Amp / 7.4 kW)

  To install a charger with a higher rating, it must incorporate one of the load-management options approved by Energex or Ergon Energy. These options include:

  • Connection to the primary tariff with basic active management (using a network device).

  • Connection to a load control tariff (Tariff 31 or 33) managed by a network device.

  • Connection to the primary tariff with dynamic connection for load balancing.

    
    

These regulations are essential to the sustainable power strategy of Queensland, to guarantee that EV charging will not overload the local grid, especially when peak demand periods arrive.

Futureproofing Your Home: The National Construction Code (NCC) 2022

The National Construction Code (NCC) 2022, effective in Queensland from October 2023, was implemented as part of embracing a greener, future ready housing market.  A new building requirements were set under this code for EV charging readiness:

• New Homes (Class 1): Must now include a dedicated 32-amp circuit running from the switchboard directly to the garage or carport, this will prepare the property for a future EV charger installation.

• Apartment Buildings (Class 2): 100% of all car parking spaces must be designated as “EV-ready.”

• Commercial Buildings (Class 5–9): 20% of all car parking spaces must be designated as “EV-ready.”

  
  

The goal of this change of regulations is to ensure that new constructions in Queensland are being built with the integration of future electric vehicle charging needs.

EV Charger Installations in Rental Properties

Before installing an EV charger, tenants must secure a written permission from the property owner or manager. Although property owners are not obligated to approve, they are not allowed to pass on any extra insurance expenses to the tenant in case consent is given.

Here in Axon Electrical we offer professional consultation to ensure clear compliance of the process and with regulations.
