Generator Changeover Switches
Connect Your Generator the Right Way
Without correct isolation from the grid, back-fed generator power can travel along supply lines and put utility workers, neighbours, and your own property at serious risk. A professionally installed changeover switch eliminates that danger entirely by isolating your circuits before generator power flows.
At Mountain Breeze, our licensed electricians install changeover switches that meet all Victorian electrical standards and integrate cleanly with your existing switchboard. When the grid drops, you switch to generator supply knowing the right circuits are powered and the mains connection is safely locked out.
Why You Need a Proper Changeover Switch
Legal Compliance
Connecting a generator to your property without an approved changeover switch violates Australian electrical regulations. A compliant installation protects you from legal liability and potential fines.
Safety for Everyone
A changeover switch prevents dangerous back-feeding into the grid, protecting line workers, neighbours, and your own property from electrical hazards during an outage.
Selective Circuit Powering
Not every circuit in your property needs generator power. A changeover switch lets you direct supply to your most critical loads - lights, refrigeration, communications, security - without overloading the generator.
Quick, Reliable Switching
When the power drops, you want to be up and running fast. A changeover switch provides a clear, simple process for transferring your supply from grid to generator and back again - safely and without fuss.
Generator Changeover Switches - FAQs
What is a generator changeover switch?
It is a switching device installed at your switchboard that safely isolates your property from the grid and redirects power from your generator to selected circuits. It prevents generator power from feeding back into the mains, which is both illegal and extremely dangerous.
Do I need one if I only use a portable generator?
Yes. Any generator connected to your property’s wiring – whether portable or permanently installed – requires a compliant changeover switch. Plugging a generator into a wall socket or wiring it directly to your board without one is unsafe and against regulations.
Can a changeover switch work alongside my solar system?
Yes. We can integrate a changeover switch with your existing solar and battery setup to provide layered backup options. During an outage, your battery handles the first line of defence, and the generator picks up if the battery runs flat.
What is the difference between a manual and automatic changeover switch?
A manual switch requires you to physically flip the changeover when the power goes out. An automatic transfer switch detects the outage and activates the generator without any intervention. We install both types depending on your property’s needs and budget.
How long does installation take?
Most changeover switch installations are completed within half a day. If additional switchboard work is required, it may take a little longer. We will provide a clear timeline as part of your quote.
