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.
From the original fuse board
to a more considered electrical setup.
01 / THE FOUNDATION OF YOUR HOME
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.
Based in Lalor, Voltra Electrical carries out switchboard upgrades and fuse box replacements across Melbourne’s north and the wider metropolitan area.

Repeated tripping needs investigation. The cause could be an appliance, wiring or a circuit fault. We identify the problem before recommending a switchboard replacement.
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
A modern switchboard brings the right protective devices together. We explain what is being fitted and why it belongs in your installation.
THREE-PHASE POWER
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.

SURGE PROTECTION
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.

SOLAR, BATTERY & EV READY
Solar, home batteries and EV chargers all connect through the switchboard. Planning for them during an upgrade saves reworking the board later.
WHAT AFFECTS THE PRICE
Every switchboard is different, so we give a fixed written price after seeing yours. These are the things that change it.
03 / REAL VOLTRA WORK
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. DRAG TO COMPARE.
Before
After04 / FROM FIRST LOOK TO FINAL CHECK
We check the board, existing circuits, earthing and planned additions. Tell us about any recurring faults and what you want to add in future.
You receive a clear scope and written price. We explain the proposed equipment, any additional work and the planned power interruption before booking.
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.
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
Old ceramic fuses, missing safety switches, limited circuit space or visible deterioration are reasons to arrange an assessment. Tripping can also point to a separate fault, so a new board is not automatically the answer. We inspect the installation and explain what is needed.
The price depends on the number of circuits, the enclosure, access, existing wiring and earthing, and whether supply or other remedial work is needed. Inspection requirements also affect the scope. We provide a written quote after assessing the job, rather than promise a one-size-fits-all price.
Power needs to be isolated during the replacement. The duration depends on the existing installation and the work required, including inspection before reconnection. We confirm the expected outage when planning the job so you can organise access and anything that relies on power.
We need agreed access to the switchboard and the areas required for testing. We organise this with you before the job, including who will be available for access and handover.
No. We check the existing board, circuit protection, available space and supply capacity against the proposed installation. Some homes need an upgrade; others can use their existing board. Replacing a switchboard does not, by itself, increase the electricity available from the street.
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.
Yes. Electrical installation work in Victoria requires a Certificate of Electrical Safety. A residential main switchboard replacement also requires independent inspection before it is energised. Voltra Electrical is a registered electrical contractor, REC 37324.
Yes. We first check whether three-phase is actually needed for what you plan to run. If it is, we handle the switchboard work and lodge the supply request through your retailer for the distributor's approval.
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.
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.
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.
