Is Your Adelaide Home Electrically Safe? Q&A With the Team at aba ELECTRICAL
Most electrical faults don’t give themselves away with sparks, smoke or sudden power cuts.
More often, it is the subtle warning signs – an ageing switchboard, a smoke alarm that hasn’t been tested in years or wiring behind walls – that highlight the importance of regular safety checks. Homeowners will recognise these signs, feel responsible, and know that proactive steps can keep their homes safe.
Much of Adelaide’s older housing stock, especially that built before the 1990s, has outdated electrical infrastructure that may be unsafe. Discussing these potential risks can encourage homeowners to schedule professional inspections for reassurance and safety.
To help homeowners better understand the condition of their electrical systems, we sat down with the licensed team at aba ELECTRICAL to answer some of the most common questions they receive.
Q: How do I know if my home is electrically safe?
aba ELECTRICAL:
Many electrical faults stay hidden until a switchboard fails, a circuit repeatedly trips, or an inspection uncovers a problem.
Rather than waiting for something to go wrong, understanding the key indicators of a well-maintained electrical system – such as flickering lights or burning smells – can help homeowners recognise when an immediate professional assessment is needed to prevent hazards.
A home is generally considered to be electrically safe when:
- The switchboard meets current standards
- Safety switches (RCDs) installed and working as intended
- Smoke alarms are compliant and tested
- Good-condition wires—no signs of overheating, burning smells or recurring electrical faults.
- Wiring is in excellent condition.
- There are no signs of overheating, burning smells, or recurring electrical faults.
Older Adelaide homes, particularly those built before the 1990s, often have older electrical infrastructure. Homeowners can avoid potential problems by having their wiring inspected regularly by a professional. This helps keep them safe and up to code.
Q: Are smoke alarms really that important—even if nothing’s ever happened?
aba ELECTRICAL:
Absolutely.
Smoke alarms remain one of the most important safety devices in any home. However, simply having an alarm installed isn’t enough. It must be correctly positioned, regularly tested, and compliant with current requirements.
In South Australia, smoke alarm compliance is particularly important when selling or renting a property.
Some of the most common issues we encounter include:
- Service life of smoke detectors
- battery-operated units where hardwired systems are recommended
- Long periods of ignoring false alarms
- Wrong location all over the home
Regular testing of your smoke alarms and compliance checks will help ensure they are working correctly and in compliance with current standards.
Compliance matters, but the real benefit is knowing your home has an effective early warning system should an emergency occur, helping homeowners feel secure and in control of their safety.
Q: What exactly is a safety switch (RCD), and do I need one?
aba ELECTRICAL:
A safety switch, also known as an RCD (Residual Current Device), is designed to disconnect power almost instantly when it detects an electrical fault.
If a damaged appliance, exposed wiring, or a faulty circuit poses a risk of electric shock, the RCD provides an additional layer of protection.
Modern homes are required to have safety switches protecting power and lighting circuits. However, many older Adelaide properties still use outdated fuse boards or offer limited protection.
If your switchboard doesn’t have clearly labelled safety switches, consider installing them and upgrading to surge protection. This is one of the most effective ways to improve the overall safety of an older electrical system.
Q: What are the warning signs of an outdated switchboard?
aba ELECTRICAL:
Switchboards often receive little attention because they work quietly in the background.
However, they play a critical role in managing and protecting your home’s electrical system.
Typical warning signs are:
- Ceramic fuses vs modern circuit breakers
- No visible safety switch (
- Frequent tripping
- Buzzing sounds
- Marks or discolouration from heat
- Limited capacity for modern electrical demands
We use much more electricity in our homes today than we did a few decades ago. Air conditioning, induction cooktops, home offices, EV chargers and multiple connected devices are straining older infrastructure.
For homeowners in suburbs such as Norwood, Prospect, Unley, and other established Adelaide areas, outdated switchboards are a common finding during inspections.
A switchboard upgrade for older Adelaide homes can improve reliability, increase capacity, and help ensure compliance with current Australian Standards, giving homeowners peace of mind about their electrical safety.
Q: How often should wiring be inspected?
aba ELECTRICAL:
There is no requirement for annual wiring inspections in most residential properties.
However, we commonly recommend inspections:
- When purchasing a property
- Before selling a property
- After major renovations
- When a home is more than 25–30 years old
- If recurring electrical issues are occurring
Some warning signs that wiring may require attention include:
- Flickering lights
- Burning smells around outlets
- Centres of Hot Power
- Repeated circuit breaker tripping
- Mysterious power losses
Older houses may have wiring with deteriorating insulation. Water infiltration and rodent activity can also damage electrical systems without any obvious visual signs.
A comprehensive electrical safety inspection helps identify these issues before they lead to higher repair costs or electrical hazards.
Q: Are electrical DIY fixes ever safe?
aba ELECTRICAL:
In Australia, a licensed electrician must legally carry out most electrical work.
More importantly, electrical systems are complex, and a quick DIY repair can create risks that you might not see right away.
Our team regularly encounters properties where well-intentioned DIY work has resulted in:
- Damaged circuits
- Burnt electrical wires
- Fire hazards
- Insurance headaches
Sometimes a simple fix only addresses a bigger problem.
The best and safest course for the homeowner is to have a professional diagnose and repair.
