A standard 7 kW wall charger runs on a 32A circuit. That's above the 20A limit that triggers network notification rules in NSW, VIC, QLD, and SA. Your licensed electrician lodges the notification or application. You don't deal with the network yourself.
QLD has the most specific rules. A charger rated above 20A needs one of three compliance options under QECM v4.docs.evnex.comView source SA requires a formal exemption for chargers above 20A single-phase or 25A three-phase per phase.sapowernetworks.com.auView source WA, TAS, ACT, and NT don't require formal notification for a standard home install.westernpower.com.auView source
From December 2024, chargers above 20A in states with the notification rule must also support demand response under AS 4755.energymining.sa.gov.auView source An OCPP-capable charger satisfies this.ausgrid.com.auView source
What is a DNSP and why does your charger need to involve one?
Your DNSP is the company that owns the power lines between the grid and your home. In NSW that's Ausgrid or Endeavour Energy. In south-east QLD it's Energex. In SA it's SA Power Networks. In WA it's Western Power.
Add a big load to the network and the DNSP wants to know about it. A 7 kW charger draws as much as a large electric oven running flat out. Now picture a whole street of new EV owners. The local transformer starts to matter.
Four states have rules for this. Notification (or exemption in SA) lets the DNSP track new loads. Where needed, it adds a demand-response control so they can briefly cut charger output during a peak.
Which states require DNSP notification?
NSW, VIC, QLD, and SA all require notification for EV chargers drawing more than 20A on single-phase or more than 40A on three-phase. A standard 7 kW wall charger uses 32A. That puts it above the 20A limit every time.
WA, TAS, ACT, and NT don't require formal notification for a standard home install.westernpower.com.auView source You still need a licensed electrician in every state. Those four states just don't add an extra DNSP step on top of the normal electrical work.
In NSW, VIC, and SA, notification isn't approval. The DNSP logs the new load and may check network capacity. But they don't approve or reject a standard home charger.ausgrid.com.auView source QLD works differently. That's covered below.
The AS 4755 demand-response requirement: what it means for the charger you buy
From December 2024, new chargers above 20A in states with the notification rule must support demand response under AS 4755.energymining.sa.gov.auView source The key mode is DRM0. It lets the DNSP send a signal to pause charging briefly during a peak.ieefa.orgView source
The easiest way to meet AS 4755 is an OCPP-capable charger. OCPP is an open standard. It lets a charger receive demand-response signals from a DNSP or management platform.ieefa.orgView source
Not all popular chargers support OCPP. The Tesla Wall Connector doesn't support it as at the time of writing. In states with the rule, that means it needs another path. In QLD, you'd typically limit it to 20A (4.6 kW) or wait for Energex to fit a network device. Your electrician will know the options.
State-by-state DNSP rules at a glance
What your electrician needs to do before your charger runs at full power depends on your network. Here's the picture for each state as of June 2026.
| State | DNSP(s) | Notification threshold | What's required | How the electrician applies |
|---|---|---|---|---|
| NSW | Ausgrid, Endeavour Energy, Essential Energy | Above 20A single-phase or 40A three-phase | Network notification + AS 4755 demand response (DRM0) | Electrician notifies DNSP via connection portal; connection application needed if supply upgrade required |
| VIC | CitiPower, Powercor, AusNet, Jemena, United Energy | Above 20A single-phase or 40A three-phase | Network notification + AS 4755 demand response (DRM0) | Electrician notifies the relevant DNSP |
| QLD | Energex (SE QLD), Ergon Energy (regional) | Above 20A nameplate (single-phase) | Active device management under QECM v4: one of three paths | Electrician submits EWR via Energex portal; Energex won't proceed without it |
| SA | SA Power Networks | Above 20A single-phase OR above 25A per phase (three-phase) | Formal exemption required | Electrician gets exemption via SmartApply at generation.sapowernetworks.com.au |
| WA | Western Power | No formal threshold (standard supply is 63A single-phase) | No formal notification for standard home install; electrician checks load vs connection limit | If load exceeds limit: apply for upgrade OR fit smart EVSE with grid import limiting |
| TAS | TasNetworks | No formal threshold stated for standard residential install | No formal notification for standard home install; bidirectional chargers need connections portal | Connections portal for V2H/V2G only |
| ACT | Evoenergy | Level 2 chargers above 7 kW may need three-phase supply | Basic design application if upgrading to three-phase for a Level 2 charger | Evoenergy connections |
| NT | Power and Water Corporation | Not confirmed from primary source | No formal notification confirmed | Confirm with your electrician and local network |
Current as at June 2026. Rules can change. Your electrician will check the latest before the job. General information only, not a substitute for advice from a licensed electrician.
The Queensland rules in detail: three ways to connect above 20A
QLD has the most detailed rules for home EV charger installs. Under QECM v4, any charger with a nameplate above 20A single-phase must use one of three options.docs.evnex.comView source A standard 32A / 7.4 kW charger is above that.
Your three options are:docs.evnex.comView source ocularcharging.com.auView source
Option 1: limit the charger to 20A (4.6 kW). This sits below the limit. No network device needed. The trade-off is speed: about 25 km of range per hour instead of 40 km/hr at full 32A. No wait time.
Option 2: full 32A (7.4 kW) on primary tariff with a network device. Energex fits the device at your home. This takes up to two months. Once in, the charger runs at full speed. The network can briefly pause it during a peak.
Option 3: full 32A (7.4 kW) on a load control tariff (Tariff 31 or 33). You get a lower power rate. But Energex can switch the supply off and on each day. It won't work with solar-divert charging.
Three-phase exception: a 22 kW three-phase charger (32A per phase) can connect without any of these, as long as it switches across all three phases at once.docs.evnex.comView source
In every case, the electrician submits an Electrical Work Request (EWR) via the Energex portal.docs.evnex.comView source Energex won't fit the network device until the EWR is in.
The South Australia exemption: what it is and how your electrician gets it
SA Power Networks uses a formal exemption, not a plain notification. For single-phase, the limit is 20A. For three-phase, it's 25A per phase.sapowernetworks.com.auView source A standard 32A single-phase charger is above the limit.
Your electrician gets the exemption via SmartApply.sapowernetworks.com.auView source It's the formal step that clears the higher-amperage connection. It's not a long process.
SA also has its own EVSE guideline from the Technical Regulator (from 1 July 2024).energymining.sa.gov.auView source Chargers installed before 1 July 2026 don't have to meet the demand-response section yet. After that, SA rules align with AS 4755.
An electrician who works in SA will know this process. When comparing quotes, ask if they've done SmartApply before.
WA, TAS, ACT, and NT: what applies (and what doesn't)
Western Power's standard connection in WA gives homes 63A single-phase.westernpower.com.auView source A 7 kW charger fits inside that. No network notice needed for a standard install. If the site load exceeds the limit, the electrician applies for an upgrade or fits a smart charger with grid import limiting. Bidirectional chargers (V2H or V2G) need an Embedded Generation Connection application.
TasNetworks has no formal notice rule for a standard home install. Bidirectional chargers need the TasNetworks connections portal. They must meet AS 4777 and appear on the CEC approved inverter list.tasnetworks.com.auView source
In the ACT, Evoenergy runs connections. If your charger needs three-phase power (common for Level 2 chargers above 7 kW), you apply through a basic design process with Evoenergy.evoenergy.com.auView source
For NT, no formal notice rule was confirmed from a primary source. Check with your electrician and local network.
What your electrician does on your behalf
You don't deal with the DNSP. Your licensed electrician handles it all.ausgrid.com.auView source docs.evnex.comView source
Before the install, they check your site. That means your switchboard, the cable path, and your power supply type. In states with a notification rule, they'll check which DNSP step applies and whether your charger meets AS 4755.ausgrid.com.auView source
In NSW and VIC, they notify via the DNSP's portal. In QLD, they send an EWR to Energex.docs.evnex.comView source In SA, they get an exemption via SmartApply.sapowernetworks.com.auView source
After the install, they issue a compliance certificate. In NSW it's a CCEW. In VIC it's a CES. Other states have their own. This is your proof the job meets Australian standards.
It's all your electrician's job. Your role is to pick the right charger and make sure your electrician knows the state rules. Worth asking before you book.
How your charger choice affects the approval process
In NSW, VIC, QLD, and SA, an OCPP-capable charger is the simplest path to full 32A. OCPP lets the charger receive demand-response signals from the network. That satisfies the AS 4755 DRM0 rule.energymining.sa.gov.auView source Most modern wall chargers (Zappi, Ocular, Wallbox, Evnex) support OCPP.
A non-OCPP charger needs another path. In QLD, that's either limiting it to 20A (4.6 kW) or waiting up to two months for Energex to fit a network device.docs.evnex.comView source In other states, your electrician will advise.
Your switchboard also matters. If it needs an upgrade first, that work usually happens in the same visit. See our switchboard upgrade guide for more.
Common questions about DNSP approval
In NSW, VIC, QLD, and SA, your electrician notifies the DNSP or applies for an exemption (SA) before a standard 7 kW / 32A charger can connect. In NSW and VIC it's called notification, not approval. The DNSP logs the load but won't reject a standard install. QLD and SA have more involved processes. WA, TAS, ACT, and NT don't require formal notification for a standard home install.
Yes, in south-east QLD. A charger above 20A nameplate needs one of three options under QECM v4. Your electrician submits an EWR through the Energex portal. Energex won't fit a network device without it. If you limit the charger to 20A nameplate (4.6 kW), you don't need a network device.
Under QECM v4, any charger above 20A nameplate must use active device management. A standard 32A / 7.4 kW charger is above that. Three options: limit to 20A (4.6 kW); run at full 32A on primary tariff with an Energex network device (up to 2 months to fit); or use a load control tariff (T31/T33) that lets Energex switch supply on/off daily. A 22 kW three-phase charger is exempt when switched across all three phases at once.
For NSW, VIC, and SA, your electrician handles notification or exemption before or at installation. It usually doesn't delay the job. In QLD, Option 2 (full 32A with a network device) can take up to 2 months for Energex to fit the device. Option 1 (20A limit) and Option 3 (load control tariff) don't need a network device, so there's no wait.
OCPP is the easiest way to meet the AS 4755 demand response rule, mandatory above 20A in NSW, VIC, QLD, and SA from December 2024. Alternative compliance paths exist, but OCPP is the most direct. A non-OCPP charger needs another path. In QLD that's typically limiting to 20A or using a load control tariff. Your electrician can recommend an OCPP-capable charger for your install.
The Tesla Wall Connector doesn't support OCPP as at the time of writing. In NSW, VIC, QLD, and SA it needs another compliance path. In QLD the typical options are limiting to 20A nameplate or using a load control tariff. Confirm the current situation with a licensed electrician before you buy.
No formal notification is needed for a standard home install in WA, TAS, ACT, or NT. You still need a licensed electrician. In WA, if your load would exceed the connection limit, your electrician applies for an upgrade or fits a smart EVSE with grid import limiting. In TAS and ACT, check with your electrician for any recent changes.
An EWR (Electrical Work Request) is the document an electrician sends to a DNSP when doing electrical work that affects the network. In QLD, your electrician submits it via the Energex portal for any charger install that needs a network device. It records the work and lets Energex proceed. Your electrician handles it. You don't submit anything.
This is general information only. It isn't a substitute for advice from a licensed electrician. EV charger work is licensed electrical work in Australia. Rules change. Your electrician will check the current requirements for your state and network before the job.
