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.
We carry out switchboard upgrades and fuse box replacements in Melbourne CBD 3000, assessing the existing board, circuit protection and any planned additions first. We agree the scope and the quote with you before any work begins.

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
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
Yes. We cover every part of Melbourne CBD (VIC 3000), on both the Melbourne and Port Phillip sides of the council boundary. Send your street, the work you need and any access notes, and we will confirm availability and the next step. We also cover Carlton and East Melbourne.
Not always. In newer Melbourne CBD 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.
It depends on the building's rules. Work that touches common property, the building's structure or shared services usually needs approval, while work inside your own apartment may not. 99% of homes in Melbourne CBD are flats or apartments, so we check the building's requirements with you before booking.
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.
YOUR HOME / YOUR AREA
About 54,900 people live in Melbourne CBD, in about 27,480 occupied homes (2021 Census). Melbourne CBD has homes from several decades, so boards range from original fuse panels to modern safety-switch boards. 13% of homes are mortgaged, and an upgrade is often planned alongside a renovation, solar, or an EV charger. Neighbouring Carlton (13%) and East Melbourne (27%) sit either side of Melbourne CBD on this measure.
In postcode 3000, 114 rooftop solar systems have been installed since 2001 (Clean Energy Regulator). Solar inverters and batteries connect at the switchboard, so its space and protection matter as more homes add them.
Melbourne CBD is about 18 km south of our Lalor base, in the centre of Melbourne, around Federation Square and Southern Cross Station. Melbourne CBD is split between the Melbourne council area (about 82% of the suburb) and Port Phillip. Next door, we also cover Carlton, East Melbourne, North Melbourne and Parkville.
