Expert Tips for Energex Compliant Home EV Charger Installation in Queensland

As electric vehicles become more common across Queensland, the demand for reliable and compliant EV charger installations continues to grow.

Whether you’re installing a charger at home, in a commercial property, or as part of a public charging network, safety and regulatory compliance must come first. Here are expert tips to ensure your EV charger installation in Queensland is safe, future-ready, and fully compliant.

Energex Compliance for Single Phase EV chargers in Queensland

20Amps or less

you can connect your 20Amp or less rated EV chargers to a primary tariff.

21Amps or more

When installing an EV charger that exceeds 20 amps on a single-phase supply in Queensland such as a 32A single-phase dedicated EV charger must be connected by one of the following arrangements:

1. Economy tariff using a network device
2. Primary tariff with basic active management via a network device
3. Primary tariff with a dynamic connection.

The Energex Electrical Works Request (EWR) process is essential. Here are some key points about it:

1. EWR Submission: You’ll need to submit an EWR through the Energex portal. This request informs Energex about your planned installation, particularly since it involves higher loads that can impact the electrical network.
2. Technical Requirements: Ensure that our installation complies with relevant Australian standards and Energex guidelines. This includes aspects like load calculations and the need for appropriate protection devices.
3. Hardware Requirements: The EV charger should be connected to a dedicated circuit from the switchboard. This circuit must be rated appropriately for the charger’s amperage. Please see diagram on the following page

This process is crucial for ensuring that the electrical network remains safe and reliable while accommodating the increased demand from EV chargers. and Energex will not proceed with the installation if these works are not completed

Three-phase EV charging in Queensland

At a premises wired for three-phase, a dedicated 22kW (32A per phase) three phase charger when connected and switched simultaneously across all phases, can be connected without requiring the device management options. This will allow installation of a much faster charger.

Hire a Licensed and Experienced EV Charger Installer

Not all electricians are experienced in EV charger installations. In Queensland, EV chargers must be installed by a licensed electrical contractor who understands:

1. Local network requirements
2. Load balancing considerations
3. Switchboard upgrades (if required)
4. Safety compliance and testing

An experienced installer will:

1. Assess your existing electrical capacity
2. Determine if an upgrade is required
3. Handle the Energex EWR submission
4. Provide compliance certification upon completion

Choosing a qualified installer reduces risks, ensures faster approvals, and guarantees long-term reliability.

Plan for Future Capacity and Smart Charging

Installing an EV charger is an investment. Planning for future needs can save money and prevent additional upgrades later.

Future Vehicle Upgrades: You may upgrade to a faster EV or add a second vehicle. Installing infrastructure that supports higher capacity now can prevent costly rewiring later.

Smart Charging & Load Management: These features not only reduce electricity costs but also support network stability as an increasing priority in Queensland.

Installing an EV charger in Queensland isn’t just about plugging in a unit It’s about ensuring safety, compliance, and long-term reliability.

By following these expert tips, you can confidently install an EV charger that is safe, compliant, and built to support Queensland’s growing EV Charging Network. Please be sure to validate all information with Energex prior to any installation as regulations change.
