As electric vehicles (EVs) become increasingly popular across Melbourne, more homeowners are looking at installing an EV charger at home. Having your own home EV charger can make charging your vehicle more convenient, allowing you to charge overnight and start the day with a full battery.
However, before installing an EV charger, there is one important question that needs to be answered:
Can your home’s existing electrical system safely handle the additional load?
This is where a professional switchboard and electrical capacity check comes in.
At JRC Electrics, we don’t simply install an EV charger and assume your existing electrical system can handle it. We first assess your home’s electrical setup, including the switchboard and available capacity, to determine whether an EV charger can be installed safely and appropriately.
Why Does Your Switchboard Need to Be Checked?
An EV charger can place a significant additional load on your home’s electrical system. Your switchboard already supplies power to appliances and systems throughout your property, such as air conditioning, electric ovens, hot water systems, pool equipment and other high-powered appliances.
Adding an EV charger means adding another electrical load to the system.
Depending on the age and capacity of your home’s electrical installation, your existing switchboard may need to be assessed before an EV charger can be installed.
A switchboard check can help identify whether:
- Your existing electrical supply has sufficient capacity
- Your switchboard is suitable for the proposed EV charger
- Additional circuit protection may be required
- Your switchboard may need an upgrade
- There are existing electrical issues that should be addressed before installation
What Is Involved in an EV Charger Installation?
Every home is different, which is why EV charger installation should be assessed on an individual basis.
Our electricians can assess the proposed charger location and determine the most suitable way to connect it to your home’s electrical system.
This can include looking at:
1. Your Existing Switchboard
We inspect your switchboard and electrical installation to determine whether it is suitable for the additional EV charging load.
If your switchboard is older or already heavily loaded, an upgrade or other electrical work may be required before the charger can be installed.
2. Available Electrical Capacity
Your home may already have several high-powered appliances operating on the electrical supply.
We assess the existing electrical load and consider the additional demand from the EV charger. This helps determine whether the proposed installation is appropriate for your property.
3. Charger Location
The distance between your switchboard and the proposed charger location can affect the installation.
We consider the most practical cable route and the location of the charger so the installation is neat, safe and suitable for your home.
4. Appropriate Circuit Protection
An EV charger requires the appropriate electrical protection and dedicated installation requirements.
Our electricians can determine what protection and wiring arrangements are required for the charger being installed.
What If My Switchboard Doesn’t Have Enough Capacity?
Don’t worry — this doesn’t necessarily mean you can’t install an EV charger.
If your existing electrical system requires additional capacity or your switchboard needs upgrading, we can discuss the available options with you.
Depending on the property and electrical installation, this may involve:
- Switchboard upgrades
- Additional circuit protection
- Electrical improvements
- Reviewing existing electrical loads
- Discussing suitable charging options for your vehicle and home
The important thing is to identify these requirementsbefore installation rather than discovering an electrical limitation after the charger has been purchased.
Why Choose a Professional Electrician for Your EV Charger Installation?
Installing an EV charger is more than simply mounting a unit on a wall and connecting a cable.
Your EV charger becomes part of your home’s electrical system, so the installation needs to be properly assessed and carried out by a qualified electrician.
At JRC Electrics, we can help you understand what is required before you commit to an installation.
Our approach is simple:
Assess → Advise → Install
We’ll assess your existing electrical system, explain what is required, and provide a clear quote for the work.
