Many older switchboards can’t handle today’s electrical loads or safety standards. Warning signs include ceramic fuses, no safety switches (RCDs), frequent tripping, visible damage, or boards older than 25 years. Upgrading ensures compliance with Australian regulations, reduces fire and electrocution risks, and protects property and residents.
Your switchboard is the heart of your property’s electrical system. It distributes power safely throughout your home or building and protects you from electrical faults. But like any critical system, switchboards don’t last forever. Many older boards were never designed to handle today’s electrical loads or modern safety requirements.
If you’re unsure whether your switchboard needs attention, here are the key warning signs to look out for:
If your switchboard contains ceramic re-wireable fuses instead of modern circuit breakers, that’s a red flag. Fuses were standard decades ago, but they’re not designed to handle today’s appliances or safety expectations. They provide limited protection and are prone to overheating or even fire under heavy loads.
Rule of thumb: If you see porcelain blocks with wire links, it’s time to plan an upgrade.
Safety switches (also known as RCDs – Residual Current Devices) are life-saving devices that shut off power instantly if they detect current leaking to earth — protecting people from electric shock.
If your board doesn’t include RCDs on every circuit, it’s not compliant and puts you at serious risk.
Do your breakers trip often? Does power cut out when you run multiple appliances at once? This usually indicates your switchboard can’t handle the load. Modern properties draw far more power than those built in the 70s, 80s, or even 90s — air-conditioning, multiple fridges, induction cooktops, EV chargers.
A constantly tripping board isn’t just an inconvenience — it’s a warning signal.
Look for:
These issues can quickly escalate into a fire hazard and should be inspected immediately.
If your home or building hasn’t had a switchboard upgrade in more than 25 years, chances are it’s no longer compliant. Electrical safety regulations have evolved dramatically, and old switchboards simply weren’t designed with today’s safety standards in mind.
Upgrading your switchboard isn’t just about compliance — it’s about protecting lives and property. A modern switchboard with RCD protection reduces fire risk, prevents electrocution, and ensures your insurance remains valid in the event of an incident.
