FAQs

  • How do I know if my switchboard needs upgrading?

    You might notice signs such as flickering lights, frequently tripped circuits, burning smells near the switchboard or ceramic fuses instead of circuit breakers. Homes built more than 20 years ago often require upgrades to handle today’s higher electrical demands. An inspection by a licensed electrician can confirm whether your current switchboard meets safety standards and capacity requirements.

  • What happens during a switchboard upgrade?

    During an upgrade, the old fuse box is replaced with a modern switchboard equipped with safety switches and circuit breakers. Electricians will disconnect power, install the new components, test the circuits and ensure everything complies with Australian electrical regulations. The process usually takes a few hours, depending on the property’s wiring and complexity, with minimal disruption to your home or business.

  • Are safety switches and circuit breakers the same thing?

    No, they perform different roles. Circuit breakers protect electrical circuits from overloads and short circuits, while safety switches detect changes in electrical current that could indicate a person is receiving an electric shock. Modern switchboards typically combine both, offering multiple layers of protection to keep people and property safe from electrical hazards.
