Your complete guide to generator safety australia for Australian buyers.

Portable generator powering tools on a construction site

Generators must never run indoors, in garages or near windows — carbon monoxide kills within minutes in enclosed spaces. In Australia, connecting a generator to house wiring legally requires an electrician-installed changeover switch; extension leads to appliances are the safe DIY method.

In this guide the team at PowerTools Australia breaks down everything Australian buyers need to know, with straight answers and current local pricing. When you’re ready, you can shop safe, reliable generators with fast Australia-wide delivery.

Carbon Monoxide: The Silent Killer

CO is odourless and builds up fast in sheds, garages and under eaves. Run generators at least 3–5 metres from the house with the exhaust pointing away, full stop.

Legal Connection Methods

Backfeeding through a power point is illegal and lethal to line workers. A licensed electrician can fit a changeover/transfer switch; otherwise run appliances directly from the generator's outlets with rated leads.

Refuelling & Storage

Kill the engine and let it cool for two minutes before refuelling — petrol on a hot muffler is a fire cause every summer. Store fuel in approved containers, and run the carb dry before long storage.

Load Management

Start the biggest motor first, add loads one at a time, and stay under 80% of rated output for continuous running. Overloading burns out both generator and appliances.

Frequently Asked Questions

Can I run a generator in the garage with the door open?

No — CO accumulates even with the door open. Outside only, well away from openings.

Do I need an electrician to connect a generator?

For any connection to house wiring, yes — a changeover switch installation is licensed work in every Australian state.

How far from the house should a generator be?

Minimum 3 metres, exhaust facing away from windows, doors and vents.
