An upgraded switchboard from our experienced electricians will ensure your property complies with current Australian electrical safety standards and is safe from potential electrical hazards.

Why Upgrade Your Switchboard

Your switchboard is the control centre of your home’s electrical system. When it starts to struggle, you’ll notice signs like tripping breakers, flickering lights, or even burning smells. These are early warnings that your system may be overloaded, outdated, or unsafe.

Here are the most common reasons Brisbane homeowners need a switchboard upgrade, and when you might also need to upgrade from single-phase to a three-phase switchboard.

We upgrade homes and businesses with advanced switchboards that meet the current electrical requirements of the Australian Wiring Rules AS/NZS 3000:2018 to ensure they handle increased electrical loads without compromising safety.

No Safety Switch (RCD)

If your switchboard doesn’t have at least one safety switch (RCD), it’s time for an upgrade. RCDs automatically cut power during a fault, protecting against fire and electric shock. Older boards without RCD protection are no longer compliant with Australian electrical standards.

Currently Uses Old Ceramic Fuses

Ceramic fuses are outdated and provide minimal fire safety. In Victoria, they are no longer allowed in homes. It’s essential to switch to modern, safer fuses.

Circuit Breakers Keep Tripping

Frequent tripping usually means your circuits are overloaded or your switchboard can’t handle your home’s current power demand. This is common after adding high-load appliances like ducted air conditioning, EV chargers, or heat pump systems.

If your circuits trip often when you use several appliances at once, your home may be pushing the limits of single-phase power, a clear sign it’s time to consider a three-phase switchboard upgrade.

Overcrowded or Messy Wiring

If your switchboard looks overcrowded or has messy, unlabelled wiring from years of modifications, it’s not just untidy, it’s unsafe. Overloaded circuits increase the risk of overheating, arcing, and power faults.Upgrading gives you a clean, well-organised panel with room for future circuits, solar, or battery connections.

Asbestos or Damaged Components

Some older switchboards (installed before 2004) used asbestos-backed panels. These must be replaced by licensed professionals to eliminate the risk of asbestos exposure.

Burning Smells & Sparks

A burning smell or visible sparking is never normal. These are signs of serious faults, often caused by overheating wires, loose connections, or overloaded breakers. These issues require immediate attention and are often resolved through a full switchboard replacement.

Flickering Lights and Power Fluctuations

Constant flickering or dimming lights are a sign your switchboard isn’t managing power flow evenly. In homes that run multiple high-demand appliances, this can mean your single-phase supply is maxed out. A three-phase switchboard provides smoother voltage and balanced load across circuits — reducing flicker, improving stability, and protecting your electronics.

Installation And Upgrade Process

When upgrading or replacing your switchboard, our electricians will:

1. Assess your current system and power needs
2. Design a layout for new breakers, RCDs, and potential three-phase integration
3. Install and connect the switchboard safely to your mains supply
4. Label all circuits clearly and provide compliance documentation

All work follows Australian Standard AS/NZS 3000 and current Queensland safety regulations.

Regular Maintenance & Repairs

Your switchboard should be inspected and serviced by a licensed electrician every 18–24 months. Regular testing and cleaning prevent faults and reduce the risk of electrical fires.

For commercial properties, maintenance may be required more frequently to comply with workplace safety standards.

When to Upgrade to Three-Phase Power

Not every home needs three-phase power, and we’ll always tell you if you don’t.
Here are the 6 reasons why you may need an upgrade
At Precision Electrical & Air, our advice is based on your actual power use. If a single-phase system is doing the job safely, we’ll leave it as is.

You may genuinely need a three-phase switchboard upgrade if:

• You’re installing ducted air conditioning, EV chargers, or large workshop tools
• You’re adding solar panels or a battery system over 6.6 kW
• You experience power fluctuations, dimming, or frequent tripping
• You’re planning to extend, renovate, or future-proof your home

Three-phase power offers greater stability, smoother voltage, and higher efficiency for properties with heavier electrical demand, but we’ll only recommend it if it’s truly required.
