If your home still has the same switchboard it came with 30 or 40 years ago, you’re not alone. Plenty of houses across Geelong are running on electrical systems that were installed before dishwashers, air conditioners, and home offices were standard. The problem? An outdated switchboard isn’t just inconvenient. It can be genuinely dangerous.
Here are five signs it might be time to upgrade yours.
1. You’ve Still Got Ceramic Fuses or Rewireable Fuses
Open your switchboard and have a look. If you see chunky ceramic fuse holders or fuse wire wrapped around a carrier, your switchboard is seriously outdated. These were common in homes built before the 1980s, and while they did the job back then, they don’t meet current Australian standards (AS/NZS 3000).
Rewireable fuses have a nasty habit of being “fixed” with the wrong gauge wire. We’ve seen homes in Belmont and Highton where someone has jammed in thicker fuse wire to stop it blowing. That defeats the whole purpose of the fuse. Instead of cutting power when there’s a fault, the circuit stays live and the wiring overheats. That’s how electrical fires start.
Modern switchboards use circuit breakers that trip automatically and can be reset with the flick of a switch. No guesswork, no dodgy repairs.
2. Your Circuits Keep Tripping
The occasional trip is normal. A circuit breaker doing its job when you plug in one too many heaters is actually a good sign. But if your power drops out regularly, or the same circuit trips every week, something’s wrong.
Common causes include:
- Too many appliances on a single circuit (older homes often have just two or three circuits for the whole house)
- Faulty wiring or loose connections inside the switchboard
- An overloaded switchboard that wasn’t designed to handle modern electrical loads
The average Australian home now uses around 40% more electricity than it did 20 years ago. Between split systems, electric vehicle chargers, induction cooktops, and multiple TVs and computers, older switchboards simply can’t keep up. A new switchboard with dedicated circuits for high-draw appliances fixes the problem properly.
3. You’re Renovating or Adding New Appliances
Planning a kitchen reno? Adding a granny flat out the back? Putting in a pool or spa? These projects almost always require additional circuits, and if your switchboard is already full, there’s nowhere to put them.
We get a lot of calls from Geelong homeowners mid-renovation who didn’t realise their switchboard would need upgrading. It’s worth checking early. If your switchboard only has six or eight circuits and you’re adding a new bathroom, workshop, or outdoor entertaining area, you’ll likely need a new board with capacity for 18 to 24 circuits or more.
Solar and Battery Systems
This one catches people off guard. If you’re getting solar panels or a battery storage system installed, your switchboard needs to be compatible. Many older boards don’t have the space or the right configuration for solar inverter connections. Upgrading the switchboard as part of your solar install saves you from paying for two separate jobs down the track.
4. You Don’t Have Safety Switches (RCDs)
Safety switches, also called residual current devices or RCDs, are designed to cut power within 30 milliseconds when they detect current leaking to earth. That’s fast enough to prevent electrocution in most cases. They’re different from circuit breakers, which protect wiring from overload but won’t save you from electric shock.
In Victoria, RCDs have been required on power circuits in new homes since 1991, and on lighting circuits since 2008. But if your home was built before then and hasn’t been rewired, you might not have any safety switches at all.
According to Energy Safe Victoria, electrical faults cause around 30% of house fires in the state each year. RCDs dramatically reduce that risk. Some insurance policies now require them, and if you make a claim after an electrical fire and your switchboard didn’t have safety switches, your insurer could push back.

5. There’s a Burning Smell or Scorch Marks
This one is urgent. If you notice a burning or acrid smell near your switchboard, or you can see brown or black scorch marks on the board, around the fuses, or on the surrounding wall, stop reading this article and call a licensed electrician.
Scorch marks mean something has been arcing or overheating. Loose connections, corroded terminals, and overloaded circuits all generate heat, and inside a switchboard full of plastic and wiring, that heat can lead to fire quickly.
We’ve attended jobs across Geelong where the switchboard casing has partially melted and the homeowner had no idea until they happened to open the meter box. If your switchboard is tucked away in a garage or laundry cupboard, it’s worth having a look every few months.
What Does a Modern Switchboard Look Like?
A properly upgraded switchboard will have:
- Circuit breakers instead of fuses on every circuit
- RCDs protecting all power and lighting circuits
- Clearly labelled circuits so you know what each switch controls
- Enough capacity for your current electrical load plus room to grow
- A surge protector to shield sensitive electronics from power spikes
The whole unit is typically compact, neat, and mounted in a weatherproof enclosure if it’s outside.
What Does the Upgrade Process Involve?
A switchboard upgrade usually takes half a day to a full day, depending on the complexity of the job. Your power will need to be off for a few hours while the old board is removed and the new one is wired in. Your electrician will also need to arrange an inspection with the local network distributor to make sure everything meets current standards.
Cost varies depending on the size of your home and how many circuits you need, but most residential switchboard upgrades in Geelong sit between $1,200 and $3,000. Given that it protects your family, your home, and potentially your insurance coverage, it’s one of the better investments you can make in your property.
Not Sure Where You Stand?
If any of these signs sound familiar, it’s worth getting your switchboard assessed by a licensed sparky. At LCK Electrical, we do switchboard inspections for homes across Geelong, the Bellarine, and the Surf Coast. We also service Melton, Sunbury, Werribee, and Bacchus Marsh. We’ll let you know exactly what you’re working with and whether an upgrade makes sense for your situation. Give us a call or fill out the contact form to book a time that works for you.
