The Electrical Safety Checklist

Test your RCDs monthly — press the test button on each RCD in your switchboard. It should trip immediately and reset cleanly. Slow or failed tests mean the RCD needs replacing. Know where your main switch is — if there's an electrical emergency, turning off the main switch stops all circuits. Check your switchboard type — if it has ceramic rewireable fuses, you don't have modern circuit protection. Get an electrician to assess.

Don't overload power boards — running multiple high-draw appliances from a single power board on one circuit creates fire risk. Check flexible extension cords haven't been damaged, pinched under furniture, or wrapped in ways that cause heat buildup. Replace any discoloured, warm, or loose power points.

RCDs — The Most Important Safety Device

An RCD (safety switch) is the primary electrical protection against electrocution. It detects the tiny imbalance in current that occurs when electricity flows through a person and cuts the circuit in 30 milliseconds — faster than the heart can fibrillate.

NSW requires RCDs on all new electrical work. But existing homes are not automatically required to retrofit them. The statistics on electrocution fatalities are unambiguous: the vast majority occur in premises without RCD protection on the relevant circuit. Getting RCDs installed in an older Dubbo home is the single most impactful electrical safety measure available.

When to Get a Safety Inspection

A professional electrical safety inspection is worthwhile for any home that: hasn't had electrical work done in 10+ years, has had a significant renovation without electrical assessment, is being purchased (pre-purchase inspection), is being rented (landlord compliance check), or has had any of the warning signs described above.

We carry out safety inspections across Dubbo and surrounding areas. The inspection takes 1–2 hours, covers the switchboard, visible wiring, RCDs, and power points, and results in a written report with prioritised recommendations.

Frequently Asked Questions

How often should I test my RCDs? +

Monthly testing by pressing the test button is recommended for the basic mechanical check. Professional testing with calibrated equipment should be done every 1–3 years to verify trip time and current threshold performance.

What's the difference between an RCD and a circuit breaker? +

A circuit breaker (MCB) protects against circuit overload and short circuits. An RCD protects against earth faults — the kind that can kill people. A modern switchboard has both: MCBs for each circuit, and RCDs protecting groups of circuits.
