Complete Guide to Switchboard Upgrades in Canberra (2026)

Why Old ACT Switchboards Pose Significant Risk

Many older homes throughout Canberra's established suburbs—such as Turner, O'Connor, Narrabundah, Ainslie, and Belconnen—still rely on ceramic fuses wired with copper fuse wire. These panels were installed when household power usage rarely exceeded a refrigerator, incandescent bulbs, and a television. Today's Canberra households run induction cooktops, reverse cycle air conditioning, heat pumps, computer servers, and electric vehicles.

The Warning Signs You Need an Immediate Upgrade

• Ceramic rewirable fuses: If you still have to manually re-thread fuse wire when power cuts, your system lacks life-saving RCD trip protection.
• Asbestos backing panels: Pre-1985 switchboards often contain hazardous asbestos sheeting ('Zelemite' or bitumen-asbestos composite). Licensed electricians must follow strict ACT WorkSafe removal procedures.
• Flickering lights or buzzing sounds: Indicative of loose busbars, arcing contacts, or circuit thermal overload.
• Tripping when heating or boiling a kettle: Indicates inadequate circuit distribution or undersized main incoming neutral lines.

What Does the Upgrade Include?

• Removal of obsolete ceramic fuses and old wooden or asbestos enclosures.
• Installation of individual Residual Current Circuit Breakers with Overcurrent protection (RCBOs) on each power, lighting, and appliance circuit.
• Main isolator switch and modern surge protection device (SPD).
• Testing and submission of the ACT Certificate of Electrical Safety (CES) to Access Canberra.
