Toorak's period estates often run three-phase supply through several sub-boards. We upgrade the lot properly, with heritage detail protected and paperwork sorted.

Toorak properties are rarely a single switchboard problem. Many of the larger period homes and estate properties around Grange Road, Kooyong Road and Heyington run on three-phase supply, feeding not just the main house but separate sub-boards for a garage, a pool house, or a self-contained wing.
Each of those sub-boards has usually been added at a different time, by a different electrician, for a different purpose, which means the overall setup can end up inconsistent even when individual boards look fine on their own. Add heritage cornices, ornate plasterwork and joinery that owners rightly don't want touched, and a Toorak switchboard job needs more planning than a standard suburban upgrade.
Hawksburn's apartment stock is a different scale problem but a related one — older buildings with meter panels and boards that haven't kept pace with the appliance loads modern owners expect.
In short
Near Me Electrical upgrades switchboards on Toorak's large period estates and Hawksburn apartments, including three-phase supplies and multiple sub-boards for wings, garages and pool houses. We agree a fixed price in writing and protect heritage plaster and cornices throughout. Call 0405 592 496.
A three-phase supply feeding a main switchboard and several sub-boards means each board needs to be assessed not just on its own, but in terms of how load is balanced across the phases. An inconsistent setup where one phase is heavily loaded and another barely used causes uneven performance and unnecessary wear.
We map the whole property's electrical layout before touching anything — main board, garage sub-board, pool house sub-board, wing sub-board — so the upgrade balances load properly and brings every board up to the same standard, rather than fixing one in isolation.
Toorak's period homes often have the switchboard in a location surrounded by original joinery, ornate plaster ceilings or cornices that the owner wants left completely untouched. We plan cable runs and panel positioning specifically to avoid this wherever practical.
Where sub-boards serve a pool house or garage rather than the main residence, there's usually far more flexibility, and we prioritise doing that work first if it reduces disruption to the main house.
Apartment switchboards in Hawksburn are typically single-phase and smaller in scope than a Toorak estate, but many still run on original meter panels that haven't been reassessed since the building was constructed.
For apartments we focus on bringing the individual unit's board up to standard with RCBOs and a compliant meter panel, coordinating with the owners corporation where shared infrastructure is involved.
"Three-phase board upgrade in an older Toorak home before the EV charger went in. Quoted fixed, done in a day, and nothing left to tidy up."
"Half the ground floor lost power on a Saturday. They answered straight away and had the fault traced to a dead junction box within the hour."
Not necessarily. We can prioritise based on condition and safety, upgrading the main switchboard and any sub-board showing the most concerning signs first, then working through the others. For a full three-phase property we'll give you a clear sequence and fixed price for each stage so you can plan around it.
We assess cable routes and panel placement before starting, specifically to avoid cutting through original plaster detail. Where the existing switchboard location makes this difficult, we discuss alternative positioning that still meets access and compliance requirements while minimising impact on heritage features.
Three-phase supply splits load across three power lines instead of one, which suits large properties running heavy equipment like ducted systems, pool plant and multiple sub-boards. Upgrading a three-phase switchboard means balancing load evenly across all three phases so no single phase is overworked while another sits idle.
Work on your unit's individual switchboard and internal circuits generally doesn't need owners corporation sign-off, but anything touching shared meter panels, risers or the point of attachment usually does. We identify which parts of your job fall into each category before starting.
