Your switchboard is the heart of your home’s electrical system, distributing power safely and efficiently to every circuit. But like any piece of equipment, it has a lifespan. An outdated or overloaded switchboard can put your family, property, and appliances at risk.
If you’ve never thought about your switchboard before, now is the time. In this article, we’ll cover five clear signs that your switchboard may need replacing before a small issue becomes a major problem.
Frequent Circuit Breaker Trips or Blown Fuses
If your power cuts out regularly, it’s often your switchboard trying to protect the circuit from overload. While this is a safety feature, repeated tripping is a sign the system can’t handle your current power needs.
Why it matters, It could mean your wiring is outdated, circuits are overloaded, or the switchboard itself needs replacing.
What to do, Book a professional inspection especially if this has become a weekly or daily occurrence.
No Safety Switches (RCDs)
Safety switches are now mandatory on all new switchboards in NSW. They cut power instantly when a fault is detected, protecting against electric shock.
Why it matters, Without safety switches, even a small electrical fault can cause injury or fire.
What to do, If your board still has old ceramic fuses or lacks RCDs, it’s time for an upgrade.
Flickering Lights or Power Surges
Flickering lights can be caused by loose wiring, voltage fluctuations, or an overloaded circuit. A failing switchboard can cause surges that damage appliances and shorten their lifespan.
Why it matters, Consistent voltage supply is critical for both safety and appliance health.
What to do, Have an electrician check both your switchboard and wiring connections.
Burning Smell or Discoloured Components
Burning smells, charring, or melted plastic inside the switchboard are red flags. This indicates overheating, which could lead to fire.
Why it matters, Electrical fires start silently and can spread quickly.
What to do, Turn off the main power and contact a licensed electrician immediately.
Renovations or New High-Powered Appliances
Adding an air conditioner, induction cooktop, EV charger, or spa increases your home’s power demand. If your switchboard was installed decades ago, it’s unlikely to be equipped for modern loads.
Why it matters, Overloaded circuits increase wear on your entire electrical system and create safety hazards.
What to do, Upgrade your switchboard as part of your renovation or appliance installation.
If any of these signs sound familiar, don’t delay. A switchboard upgrade isn’t just about compliance it’s about protecting your home and everyone in it.
