How do you know if your electric switchboard needs an upgrade?
One of the most common questions we receive is, “How do I know if my switchboard needs an upgrade?” Here are some signs that it may be time to consider an upgrade:
- Are your appliances struggling to operate correctly? For instance, does your air conditioning shut off unexpectedly?
- Does your circuit breaker trip every time you use certain appliances, like a kettle or oven?
- Do your lights dim or flicker when you plug in other devices?
- Does your switchboard still have older ceramic fuses?
- Have you noticed smoke or unusual sounds coming from your switchboard?
- Are you interested in upgrading from single-phase to three-phase power?
- Is your home’s electrical wiring outdated?
- Do you see smoke coming from any electrical equipment in your home?
- Are your energy bills unexpectedly high, with no clear reason why?
- Have any electrical wires melted? (Melted wiring is hazardous and should not be touched.)
- Have you noticed burn marks near your power outlets or electricity meter, or have any cables recently caught on fire?
- Are you concerned that your electrical supply may pose a health risk?
- Are your power tools unable to function at full capacity?
If you answered yes to any of these questions, we recommend contacting the friendly team at Bajic Electrical to discuss your current situation. We can assess whether repairs or maintenance would be suitable, or if an upgrade might be the best solution. Our recommendations are always based on the cost-effectiveness of the solution, compliance with legal requirements, and, above all, the safety of our customers.

Electric switchboard installations
In Australia, specific regulations apply to all electrical installations, including switchboard installations. According to the AS/NZS 3000:2018 Wiring Rules, it’s mandatory for every household or business to have an electric switchboard equipped with a safety switch.
Additionally, when a switchboard is modified or replaced, a Residual-current device (RCD) must be installed. For any alterations, RCDs are required on all final subcircuits. RCDs are also mandatory for protecting any new socket outlets added to existing circuits. If a new outlet is added to an existing circuit, RCD protection must be installed at the origin of the new wiring.
Your switchboard manages the various electrical circuits that power your home or business, balancing the electrical load and distributing power safely. Modern switchboards are designed for easy identification of each circuit, which should be clearly labeled to show what will be impacted by switching one on or off. Most switchboards are housed in metal cabinets (often called a fuse box or distribution board) located outside the property, with a common size being 600H x 600W x 250D.
During an upgrade, outdated fuses are replaced with new safety switches, adding a critical layer of protection. These safety switches are designed to “trip” off during a power surge, reducing the risk of electric shock, electrocution, and fire hazards.
At Bajic Electrical, we offer a range of switchboard installations, services, and repairs. Each job is handled with professionalism and comes with our Lifetime Labour Warranty for your peace of mind.
