Your switchboard is the central hub of your home or business’s electrical system. If it’s outdated or struggling to keep up with demand, it could be putting your safety at risk. Here are the most common signs it’s time to replace or upgrade your switchboard—especially if you’re in Perth and rely on modern appliances or high energy loads.

1. Your Switchboard Still Uses Ceramic Fuses

If your switchboard has old-style ceramic fuses instead of modern circuit breakers or RCDs (safety switches), it’s a clear sign you need an upgrade. These outdated systems aren’t designed to handle today’s power demands and lack critical safety features.

Perth homes built before the 1990s are especially likely to still have fuse boxes. Book an inspection with Voltaic Electrical to bring your home up to standard.

2. You Experience Frequent Power Trips

Are your lights flickering or your power tripping regularly? This usually means your switchboard can’t keep up with your current power usage. Adding more appliances or circuits to an overloaded board without upgrading can lead to serious electrical faults—or worse, fire hazards.

3. You Don’t Have Safety Switches Installed

Safety switches (RCDs) are required by law in modern switchboards because they protect you from electric shock. If your board doesn’t have them—or not enough of them—it’s time to upgrade. RCDs can detect current leaks and cut power in milliseconds.

4. You’ve Added High-Powered Appliances

If you’ve recently installed a pool pump, ducted air conditioning, an EV charger, or a large oven, your existing switchboard may not be up to the task. These appliances draw a lot of power and require extra circuits or, in some cases, a move to three-phase power.

Unsure if your system is ready? Voltaic Electrical can assess your switchboard and recommend the safest solution.

5. You Notice a Burning Smell or Scorch Marks

Any sign of burning plastic, warmth around the board, or visible black marks is a red flag. These can indicate overloaded circuits, faulty wiring, or loose connections—all of which are serious fire risks and require immediate attention.

6. You’re Renovating or Extending Your Home

Planning a renovation or building an extension? It’s the perfect time to check your switchboard capacity. Adding extra rooms, lighting, or outlets means more circuits—and your current board may not have room to accommodate them.

During the process we may need to turn off your electricity momentarily. Find out more about what happens during a switchboard upgrade.

7. Your Switchboard Is Over 20 Years Old

Like anything else, switchboards wear out over time. If yours is more than two decades old, chances are it’s not compliant with today’s standards and doesn’t have the safety features needed to protect your family or business.

Many homes in Perth still operate with outdated boards. Upgrading now with Voltaic Electrical can help you future-proof your property and avoid costly emergency repairs down the track.
