Older protection.
Ceramic fuses and a lack of safety switches are good reasons to have your board assessed. Age alone does not tell the whole story: we look at the condition of the installation and the protection each circuit actually has.
SWITCHBOARD UPGRADES / COOLAROO / 3048 Switchboard
upgrades.
Ready for today.
From the original fuse board
to a more considered electrical setup.
01 / THE FOUNDATION OF YOUR HOME
Switchboard Upgrades
in Coolaroo.
From everyday appliances to your next EV charger, it all starts at the switchboard. We assess your existing setup, explain what needs attention and plan an upgrade around your home.
We carry out switchboard upgrades and fuse box replacements in Coolaroo 3048, assessing the existing board, circuit protection and any planned additions first. Tell us about your property and what you have in mind, and we will explain the scope and the next step.
Talk to us about your switchboardA fault that keeps returning.
Repeated tripping needs investigation. The cause could be an appliance, wiring or a circuit fault. We identify the problem before recommending a switchboard replacement.
More planned for your home.
An EV charger, induction cooking or a renovation can change what you need from the board. We check available space, circuit protection and the electrical supply before recommending additional work.
02 / WHAT CHANGES BEHIND THE COVER
Different jobs.
Working together.
A modern switchboard brings the right protective devices together. We explain what is being fitted and why it belongs in your installation.
- Circuit breakers
- Protect circuits against overloads and short circuits.
- Safety switches
- Detect current leaking from a circuit and disconnect power to reduce the risk of electric shock. They provide additional protection, not a guarantee against every electrical injury.
- Combined protection
- An RCBO combines safety-switch and circuit-breaker functions in one device. We select protection to suit the circuits and the installation.
- A clear, considered layout
- Labelled circuits, a suitable enclosure and space planned around the agreed work make the board easier to understand and maintain.
THREE-PHASE POWER
Three-phase upgrades.
More capacity, planned.
Most Melbourne homes have single-phase power. A three-phase supply spreads the load across three phases, which can suit homes adding large loads such as ducted air conditioning, a faster EV charger or a larger solar system. It is not always needed, so we check first.
- Do you need it?
- We look at what the home runs now and what you plan to add. Sometimes a switchboard upgrade or load management on single phase is enough.
- Distributor approval
- Changing the supply needs approval from your electricity distributor. We lodge the request through your retailer and coordinate the connection.
- Meter, mains & switchboard
- A three-phase supply usually involves a new meter, a larger mains cable to the board and a switchboard set up for three phases.
- Planned power interruption
- The changeover needs the power off. We agree the timing with you and the distributor before the day.
- Testing & certificate
- We test the installation and provide a Certificate of Electrical Safety for the electrical installation work.
SURGE PROTECTION
Surge protection.
Fitted at the switchboard.
A surge protection device in the switchboard helps protect the home's wiring and appliances from sudden voltage spikes, such as those from lightning or faults on the network. It is often added during a switchboard upgrade.
- What it does
- It diverts a sudden spike in voltage to earth before it travels through your circuits. It reduces the risk of damage; it cannot stop every surge.
- Not a safety switch
- Surge protection guards equipment against voltage spikes. Safety switches protect people from electric shock. A modern board can have both.
- Whole house or power board
- A switchboard device covers the whole installation. Plug-in surge boards add a second layer for TVs, computers and other sensitive equipment.
- What it needs
- Space on the board and a sound earth. We check both, and fit it with an upgrade or as a separate job.
- Solar, batteries & EV chargers
- Homes with solar inverters, batteries or EV chargers have more electronics on the supply, so surge protection is worth discussing at the same time.
- Check the indicator
- Many devices have a status window that shows when the cartridge needs replacing, like the one pictured.
SOLAR, BATTERY & EV READY
Ready for what comes next.
Solar, a battery or an EV.
Solar, home batteries and EV chargers all connect through the switchboard. Planning for them during an upgrade saves reworking the board later.
- Space for new circuits
- We leave room on the board for the circuits and protection that new equipment will need.
- Supply & capacity
- We check the main switch rating and supply against what you plan to add, and explain if load management or a supply upgrade is worth considering.
- EV chargers
- A home charger usually needs its own circuit. Planning it with the upgrade avoids opening the board twice.
- Working with your solar installer
- If a solar or battery installer is connecting later, we prepare the board and can coordinate with them.
- Clear labelling
- Solar and battery systems add extra isolation points. Clear labels help anyone working on the board later.
WHAT AFFECTS THE PRICE
What affects the price?
The factors, explained.
Every switchboard is different, so we give a fixed written price after seeing yours. These are the things that change it.
- Number of circuits
- More circuits mean more protection devices, and every circuit is tested.
- Safety switch arrangement
- Individual safety switches (RCBOs) on each circuit, or shared safety switches, change the parts and the layout.
- The meter panel
- Older meter panels can be worn or may contain asbestos. If the panel needs replacing or specialist removal, we explain that before quoting.
- Earthing & existing wiring
- Testing can find earthing or wiring faults that need fixing before the new board is turned on.
- Mains & supply
- Some upgrades also need a new mains cable or a supply change through your distributor.
- Independent inspection
- A main switchboard replacement is inspected by an independent licensed electrical inspector before power is restored.
03 / REAL VOLTRA WORK
Same home.
A new beginning.
The genuine before and after of one Voltra switchboard upgrade. The original fuse board gives way to a new enclosure with individually labelled circuit protection.
SCROLL TO REVEAL
Before
After
04 / FROM FIRST LOOK TO FINAL CHECK
Clear at every step.
- 01
Assess the existing setup.
We check the board, existing circuits, earthing and planned additions. Tell us about any recurring faults and what you want to add in future.
- 02
Agree on the work.
You receive a clear scope and written price. We explain the proposed equipment, any additional work and the planned power interruption before booking.
- 03
Install, label and test.
We replace the agreed equipment, identify the circuits and carry out electrical testing. Any existing wiring issues are explained rather than hidden by a new enclosure.
- 04
Inspect and hand over.
For a residential main switchboard replacement, an independent licensed electrical inspector must inspect the work before power is restored. We arrange the required inspection and Certificate of Electrical Safety, and explain your new setup.
05 / BEFORE YOU BOOK
Good questions.
Clear answers.
Do you provide switchboard upgrades in Coolaroo?
Yes. We cover every part of Coolaroo (VIC 3048). Include your street and a short description of the job, and we will come back to you about timing. We also cover Broadmeadows and Dallas.
Does my Coolaroo home need a switchboard upgrade?
Not always. In newer Coolaroo homes the board is usually modern; the question is whether it has room and capacity for what you want to add. We inspect the board and explain what needs to change before any work is agreed.
Will my Coolaroo switchboard handle solar or a home battery?
It depends on the board's space, protection and the supply. 169 home batteries have been installed in postcode 3048 since July 2025 (Clean Energy Regulator), and each one connects through the switchboard. We check the board before new equipment is added and explain any changes it needs.
Does a new switchboard mean the house needs rewiring?
Not necessarily. A switchboard upgrade and a house rewire are different jobs. Testing may identify wiring defects that need attention, but we explain those findings and the proposed scope rather than assume the whole house needs rewiring.
My safety switch keeps tripping. Do I need a new switchboard?
Not necessarily. Tripping usually points to a fault on a circuit or an appliance rather than the board itself. We find the cause first and explain whether the safety switch or the board needs to change.
Can you fit a surge protector to my switchboard?
Usually, yes. A whole-house surge protection device fits in the switchboard if there is space and a sound earth. We check both and can fit it during an upgrade or as a separate job. It reduces the risk of damage from voltage spikes but cannot prevent every surge.
Can you assess my board from a photo?
A clear photo of the accessible front of your switchboard can help start the conversation. It cannot replace an on-site assessment or electrical testing. Do not remove covers or touch wiring to take a photo.
YOUR HOME / YOUR AREA
Coolaroo.
A clearer next step.
The 2021 Census counted about 1,150 dwellings in Coolaroo, home to about 3,190 people with a median age of 37. Coolaroo has homes from several decades, so boards range from original fuse panels to modern safety-switch boards. 35% of homes are owned outright, often by long-term owners whose board has never been replaced. By comparison, the share of homes owned outright is lower in neighbouring Broadmeadows (21%) and Dallas (31%).
169 home batteries have been installed in postcode 3048 since July 2025, on top of about 2,030 solar systems since 2001, according to the Clean Energy Regulator. Solar inverters and batteries connect at the switchboard, so its space and protection matter as more homes add them.
From Lalor, Coolaroo is roughly 7.0 km to the west, in Melbourne's north-west, around Coolaroo station. Coolaroo sits within the Hume council area. We also work in neighbouring Broadmeadows, Dallas, Meadow Heights and Roxburgh Park.
