Ceramic Fuses, No Safety Switch, or a Board With No Room Left
A switchboard upgrade may be worth considering if you find rewireable ceramic fuses instead of circuit breakers, no safety switch, or protection on only some circuits. A board with no spare ways can also limit your options when you need a new circuit. Heat damage, corrosion or scorching are further signs the board needs attention.
If safety switches are already fitted, safety switch testing matters too; having one is not the same as knowing it still works. A circuit that keeps tripping does not automatically mean the board needs replacing, so trace the fault first. Replacing an outdated ceramic fuse board with modern circuit protection, or adding safety switch installation where needed, may be part of the solution.
What a Switchboard Upgrade Costs, and What Moves the Price
The switchboard upgrade cost depends on what your property and existing board require. We look at how many circuits the board supplies, whether the property is single-phase or three-phase, and whether the existing enclosure can be retained or needs replacing. A 3-phase switchboard upgrade can include different equipment and requirements from a single-phase board.
For a house, the work is usually centred on your own switchboard and electrical supply. In an apartment, the job may involve a shared meter room, restricted access, strata requirements, or determining which equipment falls within your responsibility. We also check whether the meter or mains need attention, as this can change the work involved.
Rather than guess from a photo or give you a figure that may change, we assess the existing setup first. You receive a fixed quote before work starts, and nothing proceeds until you approve it.

FAQs
Frequently Asked Questions
What does a switchboard upgrade cost in Mosman?
Most single-phase residential upgrades run $900 to $2,000. Older Mosman homes with asbestos-backed boards, extra circuits, or a consumer mains upgrade sit higher. You get a written price before any work starts.
How long will my power be off?
Usually 3 to 5 hours for a standard board. A 3-phase upgrade takes longer. Book a morning slot and you will have power back by mid-afternoon.
Do I need strata or council approval?
Not for a standard upgrade inside your own unit or house. Mosman Council heritage listings and strata schemes can affect where the board sits or how it looks. We check before we quote.
Can I just add a safety switch instead?
Sometimes. If the enclosure has room and the wiring is sound, retrofitting RCDs is cheaper. If the board is ceramic-fused, undersized, or asbestos-backed, a full replacement is the only compliant option
