Certified EV Charger Installations in Cammeray

This is one of the most important questions to answer before any installation begins, and it's exactly what our site assessment covers. An EV charger on a dedicated 32A circuit draws a sustained load of around 7.2kW, which is significant compared to most household appliances. Your switchboard needs an available circuit space, a main switch rated to handle the additional load, and appropriate RCD or RCBO protection for the new circuit.

Older switchboards common in Cammeray's period homes sometimes have ceramic fuse holders rather than modern circuit breakers, limited spare capacity, or earthing arrangements that don't meet current standards. In these cases, a switchboard upgrade is recommended before adding an EV charging circuit.

For modern switchboards in newer apartments and recent renovations, available capacity is more common but still needs to be confirmed. We check the current load, available breaker slots, and earthing during the site visit before recommending the right approach.

It's possible, but there are more steps involved than a standard house installation. Strata by-laws govern what can be installed in common property areas, and charger cabling or mounting in a shared car park typically requires formal approval from the owners corporation.

The process usually starts with a written request to the strata committee, including a proposed scope of work and who will pay for the ongoing electricity use. Many schemes now have clearer by-laws around EV chargers following recent changes to NSW strata legislation, but the specifics vary between buildings.

On the electrical side, apartment EV installs sometimes require running a dedicated circuit from the basement level switchboard to the parking bay, with a separate metered supply so usage can be billed correctly. We work through strata installations regularly and can provide a scope of works letter for your owners corporation if needed.

The site assessment is a short visit to your property before any installation work is booked. It typically takes around 30 minutes and gives us the information we need to scope the job accurately and quote with confidence.

We'll look at your switchboard: available capacity, breaker configuration, earthing, and whether any upgrade work is needed before the charger circuit is added. We'll also check the proposed mounting location, planned cable routes between the board and the installation point, and any access or structural considerations that might affect the job.

If the site is straightforward, we can often confirm the scope and pricing on the day. If something needs further checking, we'll let you know before quoting so there are no unexpected additions later. There's no charge for the assessment and no obligation to proceed.

No. A home EV charger runs on mains power, so if there's a grid outage the charger goes down along with the rest of your household supply. That applies regardless of the charger brand or model.

The exception is if you have a battery storage system that provides backup power to selected circuits during a grid failure. Some battery systems, including certain Powerwall configurations, can back up a dedicated EV charging circuit, though this typically reduces charging speed significantly compared to normal grid operation.

If the power goes out while your EV is on charge, the charger simply stops. When power returns, most smart chargers will resume automatically or prompt you through the app to restart. Your vehicle and charger are both designed to handle unexpected supply interruptions safely. If backup charging during outages is important to you, it's worth discussing battery storage options when we scope the installation.
