Most people barely think twice about their switchboard, at least until something goes wrong. However, this small, wall-mounted box is one of the most important safety features in any home or business. It’s the first line of defence against overloaded circuits, electrical shocks, and even fires.
The real question is this: how do you know when your switchboard is falling behind or putting you at risk? Our licensed electricians see the same problems again and again in homes across Melbourne. From experience, we know just how much ignoring the early signs can open the door to costly and dangerous consequences.
In Australia, your switchboard (sometimes known as the fuse box) is where the electricity is organised, controlled, and distributed. It sits inside your meter box and connects your property’s wiring to the main power supply.
A typical switchboard will contain:
Without a functional switchboard, your entire electrical system will become vulnerable. Old models with ceramic fuses were fine in the 1960s, but they weren’t built to handle the energy demands of 2025, when everything from air conditioners to smart devices, multiple chargers, and induction cooktops might be running all at once.
A switchboard isn’t something you’ll need to replace often, but it’s so important to recognise when it’s no longer functioning as it should. At this point, a few issues can become even more problematic, such as brittle wiring insulation, deteriorating ceramic fuses, or circuits that struggle to keep up with modern appliances.
Sometimes, the switchboard you own simply wasn’t designed to cope with the number of devices we now plug in daily. The result? Frequent power trips, damaged appliances, and worst-case scenario, an electrical fire.
Fortunately, the solution is simple: play it safe and arrange a time to get your switchboard checked by a licensed electrician.
There are several tell-tale signs that your switchboard is due for an upgrade. Remember, what feels like a minor inconvenience today could be a major safety hazard tomorrow. Here’s what to keep a close eye on:
So, if you’re experiencing any of these issues, get in touch with us as soon as possible. We have licensed electricians in Brighton, Doncaster, Hawthorn, and various other corners of Melbourne.
The biggest danger that comes with owning an outdated switchboard is that it can allow small electrical faults to grow unnoticed. Without working safety switches and circuit breakers, overloaded wires may continue heating until insulation breaks down and sparks ignite surrounding materials.
Modern switchboards are specifically designed to prevent this. By shutting power down instantly, they minimise the chance of fire and reduce the risk of electric shock. That’s why electricians push homeowners to take warning signs seriously, because waiting too long often means the damage is already done.
It might be tempting to tinker with your switchboard if it looks outdated, but in Victoria, electrical work is strictly regulated for a reason. Attempting DIY repairs puts you at serious risk of electrocution, fire, and non-compliance with safety laws.
The job of a licensed electrician isn’t just to install new components. They’ll also test circuits, confirm proper earthing, perform other checks, and make sure the entire system meets the Australian Wiring Rules. Of course, they’re also trained to spot the exact kind of problems that most people would never notice.
Don’t attempt to handle this yourself. Call us now and connect with a local electrician in Mooroolbark, Surrey Hills, Wantirna or anywhere across Melbourne’s East.
Even if your switchboard seems fine, we’d recommend having it inspected every few years; especially in the case of older homes. You never know, it could be out-of-date or hiding a serious underlying issue.
During a professional inspection, one of our electricians can carefully inspect and test the switchboard, as well as its related equipment. This is a very valuable measure as they may uncover hidden faults, signs of wear, or other issues that would otherwise go unnoticed.
It’s also important if you’re renovating, installing new appliances, or adding new air conditioning units. These upgrades often demand more power, and without a modern switchboard, your system may not cope.
Since legislation took effect in March 2023, all Victorian rental properties are required to have modern switchboards with safety switches installed on key circuits. This is part of our state’s current rental minimum standards, and landlords who ignore this requirement face legal consequences.
Any major switchboard replacement must comply with the Electricity Safety Act 1998 and the AS/NZS 3000 Wiring Rules. High-risk work, like a full switchboard replacement, must be signed off by a Licensed Electrical Inspector before power can be restored.
This strict process ensures that upgraded systems aren’t just functional, but also legally compliant and safe.
In order to carry out switchboard upgrades in Victoria, an electrician must hold an A-Grade Licence. This is a qualification that requires years of training, apprenticeships, and passing the Licensed Electrician’s Assessment.
For commercial businesses, being a Registered Electrical Contractor (REC) is also mandatory, which means having liability insurance, technical supervisors, and issuing a Certificate of Electrical Safety (COES) for every job.
This paperwork gives you proof that the work has been tested and approved in accordance with industry standards.
In Victoria, only a licensed A-Grade Electrician can legally perform switchboard installations. To earn that licence, they must complete a Certificate III in Electrotechnology Electrician, a four-year apprenticeship, and pass the Licensed Electrician’s Assessment.
If the work is done as part of a business, the company must also be a Registered Electrical Contractor (REC). RECs must carry public liability insurance, employ technical supervisors, and issue compliance certificates for all jobs. High-risk work like switchboard replacements is then inspected by a Licensed Electrical Inspector before power can be turned back on.
This rigorous process ensures your switchboard is not only safe but legally compliant with Victorian standards.

How do I know if my switchboard needs upgrading?
If you’re dealing with frequent power trips, flickering lights across multiple rooms, or appliances that cut out unexpectedly, those are red flags. Burning smells, scorch marks, or the presence of old ceramic fuses are also clear signs it’s time to call an electrician for an upgrade.
Why is an old switchboard unsafe?
Older boards often weren’t designed to handle the number of appliances and devices we use today. Without modern safety switches and circuit breakers, small faults can go unnoticed, eventually overheating wires and elevating the risk of electrical fires.
Can I repair or upgrade a switchboard myself?
No. In Victoria, only licensed electricians are allowed to carry out switchboard work. DIY repairs put you at serious risk of electrical fires, electric shocks, and breaking the law. Licensed electricians not only install new parts but also test and certify the system to make sure it meets safety standards.
How often should I have my switchboard inspected?
Even if everything seems fine, it’s a good idea to have it checked every few years, especially in older homes. Inspections are also recommended if you’re renovating, adding new appliances, or installing something like an air conditioner, as these increase your power demands.
Are there legal requirements for switchboards in Victoria?
Yes. From March 2023, all rental properties in Victoria must have modern switchboards with safety switches on key circuits. Any major upgrade must comply with the Electricity Safety Act and the AS/NZS Wiring Rules, and high-risk work has to be signed off by a Licensed Electrical Inspector.
