Most homes have them. Most homeowners don’t know.
And the worst part? These electrical issues won’t show up until it’s too late — when the lights go out, something starts to spark, or your smoke alarm doesn’t go off when it should.
At Luno Electrical, we’ve inspected thousands of homes across Melbourne. As Master Electricians with over 160 five-star Google reviews, we know exactly what to look for — and these are the top 5 hidden dangers we find again and again.
1. 🧨 Old Cabling That’s Ready to Fail
If your home was built before the 1960s, there’s a good chance it still has VIR (Vulcanised Indian Rubber) or cotton-wound cabling.
And here’s the truth:
That stuff is a ticking time bomb.
The insulation breaks down with heat and age, leaving exposed live wires in your walls and ceiling. All it takes is one spark.
🔥 Risk: Fire, electrocution, power failures
✅ Fix: We replace it with modern, fully insulated copper cabling that meets today’s safety standards.
2. ⚠️ Your Main Switch is a Fire Hazard
This one’s sneaky — and seriously dangerous.
We often see old homes where the main switch is rated at 80 amps, but the incoming mains cable can only handle 32 amps.
What does that mean?
If there’s an overload, your cable cooks before the switch trips. That’s how fires start.
🔥 Risk: Overheated wiring, melted insulation, potential house fire
✅ Fix:
Option 1: Replace the switch with a 32Amp unit
Option 2: Upgrade to a 63Amp (single-phase) or even 3-phase system if you need more power
Don’t leave this one unchecked (hint: read our article – Switchboard Upgrades & Repairs)
3. ⚡ No Safety Switches? No Excuse.
It’s 2025. If you still don’t have safety switches (RCDs) in your home, you’re living with unnecessary risk.
These devices are designed to save your life, cutting power in milliseconds if there’s a fault or shock. Yet we regularly find homes with none — especially older properties.
🔥 Risk: Fatal electric shock, fires from faulty appliances
✅ Fix:
We’ll install RCDs on every circuit — power, lights, and appliances — and test them to Australian standards. This is non-negotiable.
4. 🔌 Dodgy or Overloaded Power Points
Two big issues here:
Cracked or broken power points and switches (shock risk ✅)
Not enough outlets (so people use power boards, double adapters, and extension leads everywhere)
Too many devices in one spot = overload = overheating = fire. It’s basic, but dangerous.
🔥 Risk: Exposed wires, socket sparks, overloaded circuits
✅ Fix:
We replace damaged outlets and install new power points where you actually need them — safely and legally.

5. 🚨 Smoke Alarms That Are… Dead
You’d be shocked how many homes have expired or non-working smoke alarms.
By law, alarms must be replaced every 10 years. And they don’t last that long on a flat battery either. If you’re relying on a beep from 2007 to save your family… it’s time.
🔥 Risk: Zero warning in a fire
✅ Fix:
We’ll test and replace all smoke alarms — and upgrade to interconnected photoelectric alarms that actually work when it counts.

So, How Many of These Are in Your Home?
If you’re like most Melbourne homeowners, at least one of these issues is hiding in your walls right now.
And no, it’s not something you should “deal with later”. Electrical faults don’t give warnings — they give you blackouts, blown appliances, or worse.
