When to Upgrade Your Switchboard

Your switchboard is the heart of your home’s electrical system. It distributes electricity safely throughout the property and powers every light, outlet, and appliance. But if your switchboard is outdated or struggling to keep up, it can pose serious risks, including fires and electric shocks.

At Easton Electrical, we specialise in switchboard upgrades and replacements across Melbourne and the Mornington Peninsula. See a full list of our services here!

In this guide, we’ll walk you through the key signs your switchboard needs upgrading, why it’s so important, and what to expect from a professional electrician.

What Is an Switchboard and What Does It Do?

A switchboard is where your home’s main electricity supply is controlled and distributed. It contains safety devices like circuit breakers and RCDs (residual current devices), which shut off power if there’s a fault, preventing dangerous situations like overheating or electrocution.

Modern homes need more power than ever before, with appliances like air conditioners, induction cooktops, home office setups, and EV chargers now common. Older switchboards weren’t designed for this level of usage, which is why upgrading is often necessary.

Signs That You Need an Switchboard Upgrade

If your switchboard is showing any of the following symptoms, it’s time to call a licensed electrician:

1. Frequent tripped breakers or blown fuses

This is a classic sign that your switchboard is struggling with electrical demand. Constant resetting is more than a hassle; it can be a fire risk if ignored.

2. Flickering or dimming lights

Lights that flicker or dim when using appliances often indicate poor voltage regulation or overloaded circuits.

3. Burning smells or scorching around the switchboard

A burnt smell, visible burn marks, or melted wiring behind your switchboard cover is a major warning sign. These symptoms usually mean excessive heat, which can lead to fires.

4. Buzzing or crackling sounds

Switchboards should run silently. Buzzing, popping or humming could indicate loose connections, faulty breakers, or arcing, all of which require immediate attention.

5. Old-style ceramic fuses

If your switchboard still has round ceramic fuses, it’s out-dated and unsafe by modern standards. These offer limited protection and don’t meet current electrical codes in Australia.

6. Limited power supply

If you’re running out of circuits, can’t use multiple appliances at once, or your breakers trip during basic usage, your switchboard likely isn’t sized for today’s power needs.

7. Appliances malfunctioning

Sensitive electronics, fridges, or washing machines acting up? Inconsistent power from an out-dated switchboard can damage or reduce the lifespan of appliances.

8. Electrical shocks or tingles

Any time you feel a shock when touching an appliance or switch, this may point to grounding issues at the switchboard level.

These symptoms don’t just affect comfort, they create real electrical safety risks, including fire hazards, electrocution and insurance complications.

Why Is It Important to Replace an Out-dated Switchboard?

Replacing an old switchboard isn’t just about convenience, it’s about protection. Out-dated switchboards are one of the top contributors to residential electrical fires in Australia. They often lack the safety switches required under AS/NZS 3000 wiring rules, leaving you and your family vulnerable.

Here’s what a modern switchboard upgrade provides:

Enhanced safety: Includes RCDs and circuit breakers to shut down faults instantly.
Fire prevention: New components reduce overheating and arcing.
Support for modern tech: Safer operation of solar systems, induction cooktops, smart homes, and EV chargers.
Insurance compliance: Some insurers may not cover claims if your switchboard is found to be out-dated or non-compliant.
Property value: Buyers and tenants are more confident in homes with updated electrical systems.

How Often Should You Replace Your Switchboard?

As a rule of thumb, switchboards should be replaced every 25–30 years, or sooner if your home shows signs of ageing electrical infrastructure. Even if everything still “works,” older systems can silently deteriorate behind the scenes.

Major renovations, adding new circuits, or increasing your energy demand are all good times to consider an upgrade. Regular inspections by a licensed electrician can help catch issues early especially if you’re managing an investment or planning a home improvement project.
