Your switchboard is the heart of your home's electrical system. If it still uses ceramic fuses or lacks safety switches (RCDs), you're at increased risk of electrical fire, and insurers and their risk engineers increasingly look at the state of the board when assessing a claim. Millar Electrics has upgraded hundreds of switchboards across Melbourne, with the work typically completed in a single day and minimal disruption. Victorian regulations require safety switch installation on power circuits in all new builds and renovations. Older homes aren't mandated to upgrade immediately, but energy providers and insurers increasingly flag outdated boards, and some policies exclude fire damage traced to a faulty fuse box: check your policy conditions.
Signs your switchboard is overdue
Ceramic fuses (porcelain holders with replaceable fuse wire) are the clearest indicator, since they pre-date safety switches entirely. Other signs: no test buttons on any modules, frequent unexplained tripping, signs of melting or discolouration around connections, an undersized board that has had circuits added piecemeal over the years, or aluminium wiring entering the board.
What an upgrade includes
We replace the entire enclosure with a modern panel sized for current and future load. Every circuit gets either an RCBO (combined RCD and circuit breaker) or grouped RCD protection. Where the consumer mains supply is also undersized or degraded we replace those at the same time, coordinating with the distributor for the metering reconnection. The job typically runs in a single day, with planned power-off windows of 1–3 hours.
Components we use
We use quality components from trusted Australian brands (Clipsal, NHP, Schneider) and take the time to document and label your board properly so future maintenance is straightforward. We provide a hand-over photo of the new board for your records and lodge the Certificate of Electrical Safety with Energy Safe Victoria.
Standards we work to
Every switchboard upgrade is installed to AS/NZS 3000 (the Wiring Rules), with the assembly itself meeting AS/NZS 61439 (low-voltage switchgear and controlgear assemblies). Consumer mains and sub-mains are sized under AS/NZS 3008 for the new circuit count plus reasonable future growth. RCD protection on the final sub-circuits (per AS/NZS 3000) is the single largest safety improvement an upgrade delivers, and the reason insurers increasingly flag old ceramic-fuse boards.
