Beat Storm Season with a Generator Changeover Switch
Power Outages in Far North Queensland Are a Matter of "When," Not "If"
Living in Far North Queensland means experiencing some of Australia’s most severe weather events. From summer monsoons to severe tropical cyclones, extreme weather frequently damages Ergon Energy overhead power lines, leaving towns, rural properties, and agricultural operations without electricity for days at a time.
While buying a portable petrol or diesel generator is a great first step, how you connect that generator to your property matters immensely for safety and convenience.
The Problem with Extension Cords
During a blackout, running long extension leads from a generator outdoors into your kitchen or living room introduces major hazards:
Trip & Fire Hazards: Cables pinched under doors or windows can fray, posing shock and fire risks.
Inability to Power Hardwired Appliances: Extension cords cannot power ceiling fans, hardwired lighting circuits, pressure pumps, bore pumps, or electric hot water systems.
Weather Exposure: Windows or doors left cracked open for extension leads allow rain, wind, and humidity inside during tropical downpours.
The Solution: A Generator Changeover Switch
A generator changeover switch is a specialized, legally mandated switch installed directly into your main switchboard by a licensed electrician. It is paired with an external, weatherproof inlet socket mounted on the outside of your home or shed.
How It Works:
When grid power drops out, wheel your generator outside and plug it into the external inlet socket using a heavy-duty lead.
Start the generator.
Flip the manual changeover switch inside your switchboard from "MAINS" to "GENERATOR".
Your home's switchboard now draws power safely from the generator, energizing your selected household circuits (lighting, refrigeration, power points, and pumps).
Crucial Safety: Preventing Dangerous "Back-Feeding"
The most vital reason to install a certified changeover switch is preventing back-feeding.
If a generator is connected directly to a home without a changeover switch that isolates the main supply, electricity can flow backward out of your house and onto the street power lines.
This energizes lines that Ergon Energy technicians assume are dead while conducting emergency repairs, creating fatal risks for line workers. A changeover switch mechanically guarantees that your home is completely disconnected from the grid before generator power is applied.
Tailored Solutions for Homes, Farms, and Sheds
At C & D Electrical and Instrumentation, we design generator connection setups based on your exact requirements:
Manual Changeover Switches: Cost-effective and reliable solutions for residential homes and rural sheds.
Automatic Transfer Switches (ATS): Ideal for commercial properties, processing facilities, or farms where backup power must start automatically the moment grid power fails.
Circuit Load Matching: We calculate your generator’s continuous output wattage and configure your switchboard so you don't overload the generator.
Prepare Before the Wet Season Arrives
Don't wait until a tropical cyclone warning is issued to sort out your backup power strategy.
