Why a Compliant Changeover Switch Isn’t Optional

Connecting a generator directly to your switchboard or power circuits without a proper changeover device can backfeed electricity back into the grid. That's a serious hazard for network linesmen working on what they believe is a de-energised line during an outage, and it's a breach of AS/NZS 3010 and the NSW Service and Installation Rules. A compliant changeover switch physically interrupts one supply before connecting the other, so the generator and mains supply can never be connected to the installation at the same time.

Manual Changeover vs Automatic Transfer Switch (ATS)

counter_1

Manual Changeover Switch

Someone physically switches the property from mains to generator supply — suited to a portable generator used occasionally during outages, where a short delay before power resumes is acceptable.
counter_2

Automatic Transfer Switch

Senses an outage and switches over on its own, typically paired with a fixed standby generator for essential services, medical equipment or server rooms that can't tolerate any gap in power.

    Frequently Asked Questions

    FAQs

    By ensuring your property is inspected by High Demand Electrical, you are taking a significant step towards securing its safety and enhancing its efficiency. Reach out today to learn more about how we can assist you in maintaining a safe and compliant electrical environment.

    Why can't I just plug a generator into a power point during an outage?

    Without a proper changeover switch, this can backfeed electricity into the grid — extremely dangerous for network linesmen and illegal under AS/NZS 3010 and NSW Service and Installation Rules.

    What's the difference between a manual changeover switch and an automatic transfer switch?

    Manual changeover requires someone to switch supply over by hand, suited to occasional portable generator use. An ATS senses an outage and switches automatically, suited to standby generators for essential services or equipment that can't tolerate a gap in power.

    How is a backup generator sized for my property?

    Via a load calculation covering the circuits you want to keep running during an outage, sizing the generator and changeover system to match rather than guessing.

      Do I need network approval for a backup generator?

      Installations must comply with AS/NZS 3010 and NSW Service and Installation Rules referencing Ausgrid and Endeavour Energy requirements. We manage the compliance side of the installation.

        What maintenance does a changeover switch or ATS need?

        Periodic testing to confirm correct isolation and switchover, particularly important for standby systems protecting essential services that may go months between real outages.

          How much does generator installation cost in Sydney?

          Depends on whether it's a simple manual changeover or a fully automatic standby system with switchboard upgrades. We provide a fixed, upfront quote after assessing your site.

            "Chris was the professional, punctual and his services are exceptional. Chris re-wired the entire property, chased the electrical work in the bathroom and kitchen areas, left a clean and tidy environment and his open communication and dialogue was a welcomed experience.

            When he quoted an arrival time, he was there. He talked me through what he was doing, and provided feedback/suggestions on how to tackle any issues. I felt part of the process, as opposed to being another Customer.

            A pleasure to deal with, and I recommend his services. I'll be definitely calling him again with any electrical work I need done."
