Mains and Switchboard Upgrade by Fitzroy North Electrician
A homeowner in Fitzroy North contacted Kenner Electrics to upgrade their consumer mains and replace their old switchboard—a smart move for any property with ageing wiring or growing power needs. Their system was running off outdated infrastructure that couldn’t safely support today’s household demands like air-conditioning, induction cooktops, EV chargers, or even just lots of modern appliances running at once. After confirming the site had access to 3-phase power, we quoted for a full 63A 3-phase mains upgrade to future-proof the home and improve overall safety.
Power supply upgrades aren’t just about compliance—they also open up more possibilities for renovations, extensions, or higher-capacity appliances down the track. On the day of the job, our team installed a new earthing system, replaced the old switchboard enclosure, and wired up the board using 10 high-quality Hager RCBOs, giving each circuit its own safety switch and overcurrent protection. We also replaced a weatherproof power point near the front entry and removed an old light that was no longer needed, cleaning up the setup nicely. Coordinating with the independent inspector and organising two supply authority truck appointments, we managed the entire process so the customer didn’t have to.
Benefits of 3-Phase Power and Upgrading to a Modern Electrical Switchboard
We installed new 16mm TPS 3-phase mains cabling, connected to a 3-phase overhead main fuse box, and fitted a new 63A main switch to handle increased capacity. The new switchboard doesn’t just meet current electrical safety standards—it also provides better load balancing, fewer nuisance trips, and allows for future additions like solar systems, EV chargers, or a battery backup system. Plus, with every circuit on its own RCBO, faults are isolated instantly without cutting power to the whole house.
It’s important to understand that new safety switches (RCDs) are much more sensitive than old circuit breakers. Occasionally, they may trip immediately if there's an existing fault in an appliance or cable that went unnoticed before—so while the system is now safer, it can reveal issues hidden by the old setup. If this happens, we’ll take the time to explain the cause and offer practical solutions. It’s all part of ensuring your home is genuinely protected, not just ticking boxes.
Planning a Renovation or Just Want Peace of Mind?
Upgrading your mains supply or switchboard is one of the best investments you can make for your home’s safety, functionality, and long-term value. If you're planning a renovation, installing a new kitchen, or thinking about going all-electric, it’s better to sort out your power supply before you're forced to—especially with supply authority delays and increasing load requirements across Melbourne.
