Your home’s switchboard is the heart of your electrical system, but it’s often out of sight and out
of mind. Knowing when it’s time to replace your home’s switchboard can help you avoid safety
risks, prevent power issues and keep your home running smoothly.
In this blog post, we’ll talk about the key signs, risks and timing to help you decide when it’s time
for you to Call Curran for an upgrade.
Signs that it’s time to replace your home’s switchboard
Your switchboard distributes electricity throughout your home and protects your circuits from
faults and overloads.
It’s also the home of safety devices like circuit breakers and safety switches (RCDs), which shut
off the power if something goes wrong.

Signs that it’s time to replace your home’s switchboard
There are a few clear indicators that your switchboard may need upgrading:
- Frequent tripping of circuit breakers
- Flickering or dimming lights
- Burning smells or heat near the board
- Old ceramic fuses instead of modern breakers
- No safety switches installed
- Limited capacity for today’s appliances
If you’re noticing any of these, it’s worth getting it checked out sooner rather than later.
Why older switchboards can be a problem
Older switchboards weren’t built for electrical demand of homes today. With more appliances,
devices, and systems in the average Australian home, outdated boards can easily become
overloaded.
They also often lack modern safety features, which increases the risk of electric shock or
electrical fires. Upgrading the switchboard helps protect both your home and the people in it.

How long does a switchboard last?
Depending on the usage and condition, most switchboards can last around 20-30 years.
If your home is older and hasn’t had an electrical upgrade in a while, there’s a good chance your
switchboard isn’t working to its full potential.
When to replace your home’s switchboard
There are some specific situations where upgrading is super important:
- During a renovation or home extension
- You’re dealing with ongoing electrical issues
- When you’re installing a high-demand appliance, like an air conditioner or EV charger
- After purchasing an older property
In these cases, upgrading your switchboard can help to future-proof your home and avoid
expensive issues in the future.
What does a switchboard upgrade involve?
A switchboard upgrade typically includes replacing old fuses with modern circuit breakers,
installing safety switches and improving circuit layout and labelling while also ensuring
compliance with current Australian standards.
