Signs You Need a Switchboard Upgrade
Most Melbourne homes built before the 1990s have switchboards that were never designed to handle the electrical demands of a modern household. Air conditioning, EV chargers, solar inverters, home theatre systems, induction cooktops, and multiple high-draw appliances all put sustained pressure on a system that was built for a simpler time. Some of the clearest signs it is time for an assessment:
Your switchboard still has ceramic fuses or rewirable fuse wire rather than circuit breakers
Circuits trip regularly or fuses blow without an obvious cause
You are adding an EV charger, solar system, air conditioner, or any high-draw appliance
Your property is being renovated, extended, or converted and the electrical load is increasing
You notice flickering lights, a burning smell near the board, or discolouration around switches or fuses
A licensed inspection has flagged your board as non-compliant or inadequate
Your switchboard has an asbestos backing panel, common in homes built before the mid-1980s
You are buying or selling a property and want the electrical system properly assessed
If any of these apply, an assessment is worth scheduling before the problem develops into something more serious or more expensive.
Switchboard Upgrade Services
We handle the full range of switchboard and mains work for residential, commercial, and strata properties across Melbourne's north east.
Mains Upgrades and Network Distributor Work
Mains work is an area where many electricians refer out or decline to quote. Bitz Electrical handles it directly. If your property needs its consumer mains upgraded, we manage the full process including the required notification to AusNet Services (the network distributor for Melbourne's north east), the physical upgrade of the mains cable, and reconnection.
Mains upgrades are required in a number of situations:
The existing mains cable is undersized for the proposed electrical load
The cable insulation has deteriorated due to age or UV exposure on the service mast
Three-phase supply is being introduced to a property currently on single-phase
The metering arrangement is being reconfigured as part of a solar or battery installation
The property is being subdivided and a new supply point is required
AusNet Services work, including changes to the service fuse or network connection point, must be coordinated through a licensed electrician with the relevant accreditation. We handle this on your behalf so the job does not stall waiting for distributor involvement.
Why an Outdated Switchboard Is a Risk Worth Taking Seriously
Old ceramic fuse boards are one of the leading causes of residential electrical fires in Australia. The mechanism is straightforward: ceramic fuses do not trip automatically when a fault occurs. They rely on a fuse wire that melts under excessive load. When that wire blows, the correct response is to replace it with the right rated wire. In practice, many older boards have had incorrect fuse wire installed over the years, sometimes heavier gauge wire that simply will not melt, which removes the only protection the circuit has.
Beyond fire risk, older boards are typically not capable of supporting the sustained loads of a modern household. Running a 6kW reverse-cycle air conditioner, a 7kW EV charger, and an induction cooktop simultaneously on a board designed for a 1970s home creates sustained overloading of wiring inside walls. This heat builds over time and is a hidden hazard that can go undetected for years before causing a fault.
A modern switchboard with appropriately rated circuit breakers and RCBOs on every circuit responds to faults in milliseconds, handles increased electrical loads safely, and gives you the documentation your insurer needs to confirm the property's electrical system is compliant.
The Asbestos Factor in Pre-1985 Melbourne Homes
Homes built before the mid-1980s across Melbourne's north east, particularly the 1960s and 1970s brick veneer stock common in Doncaster, Templestowe, Warrandyte, and Donvale, frequently have asbestos cement switchboard backing panels. This is not an immediate hazard when undisturbed, but it is a reason to use a licensed electrician who understands the handling requirements rather than attempting any DIY work near the board.

Switchboard Upgrade Cost in Melbourne
Most residential switchboard upgrades in Melbourne's north east fall in the following ranges. The main variables are the number of circuits, whether a mains upgrade is required, whether asbestos disposal is involved, and whether the property is single-phase or three-phase.
These are indicative ranges only. Three-phase upgrade costs vary significantly depending on the size of the board, condition of existing mains, and whether distributor coordination is required. We provide a fixed upfront quote after assessing your property. Call 1300 215 193 or use the form below.

Switchboard Upgrade FAQs
-
Most residential switchboard upgrades in Melbourne fall between $800 and $2,500. The range depends on the size of your home, the number of circuits, whether a mains upgrade is required, and your supply type. We provide a fixed upfront price before any work starts. Call 1300 215 193 for a no-obligation quote.
-
A full upgrade includes removal of the old board, installation of a new compliant switchboard with circuit breakers and RCDs or RCBOs on all circuits, correct circuit labelling, testing of every circuit, and a Certificate of Electrical Safety on completion. Mains upgrades and three-phase work are quoted separately where required.
-
Possibly. EV chargers and solar inverters require a dedicated circuit with adequate capacity. If your existing board does not have a spare circuit of the right rating, or if the board itself cannot support the additional load, an upgrade will be needed. We assess this as part of every EV charger and solar-related quote.
-
An RCD detects earth leakage and cuts power to protect against electrocution. A circuit breaker protects against overloads and short circuits. An RCBO combines both functions in a single device, providing full protection on one circuit independently of all others. We install RCBOs as standard, which means a fault on one circuit does not trip others.
-
Consumer mains are the cables running from the distributor's supply point to your switchboard. If your property's electrical demand increases significantly, such as when adding three-phase supply, a large solar system, or multiple EV chargers, the mains may need upgrading to handle the load. This requires coordination with AusNet Services. We manage that process directly.
-
Most residential upgrades are completed in a single day, typically four to eight hours. If mains work or three-phase conversion is also required, allow a full day and possibly a second visit for distributor coordination. We give you a clear timeframe with the quote.
-
There is no general requirement to proactively upgrade a functioning board. However, if you are adding new circuits, renovating, or your board is found to be non-compliant during a licensed inspection, upgrades may be required under AS/NZS 3000. Energy Safe Victoria requires all electrical work in Victoria to meet current standards.
-
Asbestos-backed switchboards were common in homes built before the mid-1980s. The panel must be handled and disposed of in accordance with WorkSafe Victoria requirements. We manage this as part of the upgrade process and include disposal in the quoted price. You do not need to arrange this separately.
-
Yes, in most cases. Power will be off during installation, typically four to eight hours. We advise you in advance how long the outage will last and schedule the work to minimise disruption.
-
Yes. An SPD installed at the switchboard protects all appliances and electronics from voltage spikes caused by lightning or grid events. This is particularly worth considering for properties with solar inverters, home automation systems, or expensive electronics. We can include an SPD as part of an upgrade or install one separately.
-
Both. Not every switchboard problem requires a full replacement. If your board is modern and compliant but has a faulty breaker, a failed RCD, or a labelling issue, we can repair or replace the affected component without replacing the whole board. We assess your situation first and recommend the most appropriate solution. Where a full replacement is the right answer, we explain why before quoting.
