Single phase
What most Perth homes have. A single-phase charger (commonly up to around 7kW) adds plenty of range overnight and suits the majority of households. The simplest, most common installation.

EV Charger Installation Perth
A home EV charger is more than bolting a box to the wall. It's a dedicated, protected circuit sized to your car and your switchboard's capacity. The E-LEC team assesses the supply, gets the load right and installs your charger to standard — single or three phase — across Perth and the Perth Hills.
"Can't I just use a normal power point?"
The power-point myth
Yes, you can trickle-charge most EVs from a standard 10A power point using the portable cable supplied with the car — but it's the slow, last-resort option, not a charging solution. A general power point and its circuit were never designed to deliver high current for hours at a time, night after night. Doing that repeatedly stresses the outlet, the cable and the circuit, and on older wiring that's where heat and faults start.
A dedicated EV charger sits on its own circuit, sized and protected for the job, and charges several times faster. For anyone driving regularly, it's the safer and more practical choice — and it frees up your power points for everything else.
Load considerations — getting the sizing right
The single most important part of an EV charger installation isn't the charger, it's the assessment behind it. A charger can draw as much as your whole house at peak times, so it has to be planned around what your supply and switchboard can actually deliver.
- How much current your supply and main switch are rated for
- What other large loads you run — air-conditioning, oven, hot water, pool
- When you'll typically charge (overnight charging is far easier on the supply)
- Whether load management or a smart charger is worth setting up so the car backs off when the house is busy
Getting this right means your charger is fast enough to be useful without overloading the property — and it's why we assess before we quote.
Single vs three phase
Which supply suits you
Three phase
Allows faster charging (e.g. up to ~11kW or more) and only helps if your property already has a three-phase supply, or you're bringing one in. Worth it for high-kilometre drivers or multi-EV households — but not necessary for most.
Switchboard capacity
Your switchboard decides whether a charger drops straight in or needs groundwork first. We check the available ways, the main switch rating and the condition of the board. Outcomes usually fall into one of three buckets:
- Ready to go — the board has spare capacity and room, so we add a dedicated protected circuit for the charger.
- Needs tidying or RCD work — the board is sound but needs RCD protection or a little reorganising to take the new circuit.
- Needs an upgrade first — an older or full board, or one on a fuse system, is best brought up to standard before adding a high, continuous load.
If your board falls into that last group, our switchboard upgrade service handles it as part of the same job.
What's included in an E-LEC EV charger installation
- A site visit and switchboard assessment, including supply capacity
- Advice on single vs three phase and a charger location that suits the car and the cable run
- A dedicated, protected circuit and cabling to the charger
- Mounting and connection of your chosen charger (or one we can supply)
- RCD protection appropriate to the installation
- Testing and verification before the charger is put into service
- A neat finish and the documentation appropriate to the work
If we find existing defects or unsafe conditions during the assessment, we explain what we've found and the recommended next steps before any work proceeds.

FAQ
EV charger questions
Can I just charge my EV from a normal power point?
A standard 10A power point can trickle-charge an EV using the portable cable that comes with the car, but it's slow and the circuit and outlet weren't designed for hours of continuous high load. For regular charging, a dedicated EV charger on its own protected circuit is safer and much faster. We can assess whether an existing point is suitable as an interim measure.
Do I need three phase to install an EV charger?
No. Most homes have single phase and a single-phase charger (typically up to about 7kW) suits the great majority of households. Three phase allows faster charging and only helps if your property already has a three-phase supply or you're planning to bring one in. We'll advise based on your supply and how you drive.
Will my switchboard handle an EV charger?
It depends on the spare capacity in your board and on the existing load in the home. We check the supply, main switch and available ways, and look at your other large loads. Some boards take a charger easily; older or full boards may need an upgrade or a load-management solution first.
What's included in an EV charger installation?
A site and switchboard assessment, a dedicated protected circuit and cabling to the charger location, mounting and connection of the unit, RCD protection as required, testing and verification, and the documentation appropriate to the work. We confirm the scope and any switchboard work before we start.
