If your home was built before 1980, there's a good chance the wiring behind your walls was never designed for the electrical load of a modern household. Back then, a single power point per room was normal. Today, we're plugging in smart TVs, air conditioners, induction cooktops, EV chargers and multiple devices simultaneously — all through cabling that may be 40 to 60 years old.
Here are the five warning signs Melbourne homeowners should never ignore:
1. Flickering or Dimming Lights If your lights dim when the kettle boils or the air conditioner kicks in, your circuits are struggling to share the load. This isn't just annoying — it's a sign that your switchboard and wiring can't handle modern demand.
2. Warm or Discoloured Switch Plates Touch your light switches and power points. If any feel warm to the touch, or if you notice brown or yellow discolouration around the edges, there's heat building up behind the wall. That heat is the first stage of insulation breakdown.
3. A Faint Burning Smell Near the Switchboard That acrid, hot-plastic smell coming from your meter box or switchboard area is one of the most urgent warning signs in residential electrical work. It usually means a connection is overheating or insulation is melting. Turn off the main switch and call a licensed electrician immediately.
4. Circuit Breakers That Trip Regularly Occasional trips are normal — that's what breakers are designed for. But if you're resetting breakers weekly, your circuits are overloaded. The fix isn't a bigger breaker; it's a wiring upgrade to distribute the load safely.
5. Two-Pin Power Points (No Earth Wire) If your home still has the old two-pin outlets without a third earth pin, your wiring almost certainly lacks an earth conductor. This means there's no safety path for fault current, dramatically increasing the risk of electric shock.
What to do next: Book a rewiring assessment with a licensed Melbourne electrician. At ElecPlan, we'll inspect your switchboard, test every circuit, check your earth continuity, and give you a clear written report — no jargon, no upsell. Most full-home rewires in Melbourne take 5 to 7 days and can be done with minimal disruption to your walls.
