The Real Risks of Incorrect EV Charger Installation
An incorrectly installed EV charger can cause house fires, ruin your car’s onboard charger, and void your warranty. A hard-wired charger pulls heavy current for hours, and one loose connection can arc inside your walls, fire risk, costly damage, and no insurance cover.

EV charger installation in QLD must meet the Wiring Rules and Electrical Safety Act, signed off with a Certificate of Electrical Safety.
Switchboard Upgrade for EV Charging: Why Overloaded Circuits Fail
Old switchboards were never built for EV charging: one charger adds 32 amps of continuous load, and with an oven, air conditioning and a pool pump the board runs past its limit.
How to Tell If Your Charger Was Installed Wrong
Self-check: is the charger hot while charging, do breakers trip, is there a burning smell, scorch marks, was a Certificate of Electrical Safety issued, and is it on a dedicated circuit?
Nuisance Faults vs Critical Safety Failures
Not every problem is an emergency, but you cannot tell by look alone.
| Symptom | Likely Cause | Severity | Action |
|---|---|---|---|
| Breaker trips every charge | Faulty wiring or load | Critical | Stop and call an electrician |
| Burning smell | Arcing or thermal damage | Critical | Cut power immediately |
| Scorch marks | Overheating | Critical | Cut power, call now |
Why Licensed Electrical Contractors Matter
Only a licensed electrician can legally install an EV charger and issue the compliance paperwork. A licensed electrical contractor tests the circuit, confirms the switchboard can take the load, fits RCD and surge protection, and issues a Certificate of Electrical Safety.
Post-Installation Verification Steps
Ask for an insulation resistance test, an earth continuity test, an RCD trip test, a load test under full charging current, and a thermal check on terminals.
Preventative Maintenance and Insurance Implications
An EV charger is electrical infrastructure. It needs checking, not ignoring. Book a safety inspection every year or two: your electrician checks terminals, tests protection devices, and looks for thermal damage, far cheaper than a repair.
