The Ultimate Guide: How To Connect A Backup Generator To Your House

Power outages – they’re annoying for all of us. Yes, they’re pretty rare, but they are increasingly becoming unavoidable all across Australia, especially when the weather turns dark. When the power goes out, it’s pretty grim – except when you have a backup generator. It’s not just convenient, it’s the way to keep your home running smoothly in the way you need, want and expect. How to connect generator to house? Just owning one isn’t enough. Let us explore:

Your backup generator needs to be connected safely and effectively. We’re about to walk you through everything you need to know about how to connect a generator to your house Australia wide, covering the:

• Options
• Safety considerations
• Professional advice to ensure a seamless power backup solution.

Why would you need a backup generator?

Whether it’s due to a storm, heatwave, or even maintenance, losing power can seriously disrupt everyday life. A backup generator can keep your fridge running, your home lighting shining bright, your devices charging – they can even support heating and cooling systems during a blackout.

But when connecting a generator to a house, the process requires careful planning to ensure it’s safe, effective, and compliant with Australian regulations.

Important considerations before getting started

Before we dive into the deep details, it’s essential to understand a few things upfront about generator connection to house systems:

• Generator type: This means choosing between a portable generator and a standby generator. Standby generators are installed permanently and start automatically when the power goes out, while portable generators are more flexible and less costly but require manual setup.
• Power requirements: Calculate the power you’ll need during an outage to avoid overloading the generator. Make a list of essential appliances and systems you’ll want to keep running, then verify that your generator can handle the load.
• Safety first: Backup generators can be dangerous if not set up right. Carbon monoxide poisoning, electric shock, and fire hazards are all potential risks. That’s why we recommend that homeowners rely on professional licenced electricians for connecting a generator to a house safely and legally.

Methods for connecting a generator to your home

Connecting a generator involves more than just plugging it in. You’ll need a properly set-up transfer switch to safely divert power from your generator to your home’s electrical system:

1. Using a transfer switch

A transfer switch is the safest and most efficient method of connecting a backup generator to your home. When you connect generator to house using a transfer switch, the device isolates your generator’s power from the main electrical grid, preventing dangerous backfeeding.

• Automatic transfer switch: For standby generators, an automatic transfer switch (ATS) will switch the power source automatically when it detects an outage. It provides seamless backup power and automatically disconnects when electricity is restored.
• Manual transfer switch: For portable generators, a manual transfer switch requires you to flip a switch yourself when you want to activate generator power. This option is more affordable and flexible, especially if you only need backup power occasionally.

Installing a transfer switch requires a licensed electrician, as it involves connecting the switch directly to your home electrical switchboard.

2. Interlock kit

An interlock kit is a more budget-friendly alternative to a transfer switch, often used for portable generators. An interlock kit allows you to manually switch off the main power source and connect the generator directly to your circuit panel, ensuring there’s no chance of backfeeding. Interlock kits are compatible with a variety of generators, making them a versatile option for homeowners.

However, it’s crucial to have an interlock kit installed by a licensed professional to ensure compliance with Australian standards and safety guidelines. Although an interlock kit can be effective, it doesn’t offer the automatic switching capabilities of a transfer switch, so you’ll need to manually operate it.

3. Dedicated circuits

Another option is to create dedicated circuits for essential appliances, such as the refrigerator, lights, or air conditioner. This setup means you can hook up a generator to your house to power only the essentials, reducing the load on the generator and ensuring only critical systems are backed up.

Although dedicated circuits can be a cost-effective way to stay partially powered, this approach won’t provide full-house coverage and typically requires some rewiring, which needs to be done by a professional.

Steps to connect a portable generator to your home

Still wondering how to connect a generator to your house Australia wide without using a standby system? Here are some general steps for connecting a portable generator safely:

1. Place the generator outdoors

Generators must always be placed outdoors in a well-ventilated area, at least 5 metres away from doors, windows, and vents to prevent carbon monoxide poisoning.

2. Plug into the transfer switch or interlock kit

Use an appropriate generator cord to connect your generator to the transfer switch or interlock kit. Make sure all switches on your transfer switch panel are set to “off” before connecting the power cord.

3. Turn on the generator

Follow the manufacturer’s instructions for starting the generator. After it’s running smoothly, you can then activate the transfer switch or interlock kit to divert power to your home.

4. Switch on essential circuits

With the generator running, you can begin powering essential circuits one at a time. Remember to keep your generator load within its safe operating limits to avoid overheating or tripping.

5. Monitor the power use

Keep an eye on power usage to ensure you’re not overloading the generator, and be ready to reduce load if necessary.

6. Turn off the generator when finished

Once power is restored or you’re finished using the generator:

• Switch off the transfer switch or interlock kit
• Turn off the generator
• Disconnect it from your home.

Have these steps given you a basic idea of how to connect a generator to your house? If not, it’s time to consult a licensed electrician in your area to handle the specifics. Because – be aware: Improper setup can not only damage your generator but also put your home’s wiring at risk.

Why professional installation matters

Knowing how to connect a generator to your house is valuable, but for complete safety and compliance, a licensed electrician’s expertise is essential because of:

• Electrical safety, as backup generators produce dangerously high voltage power
• Compliance with Australian standards, which are particularly strict for power generation from transfer systems
• Proper sizing and load management, requiring a perfect match between your generator and your home’s power needs
• Warranty & maintenance, with all manufacturers requiring professional installation for warranty coverage.

Safety tips for using your backup generator

Backup generators are invaluable – but they also come with risks. Need a few safety tips to keep in mind when connecting a generator to a house? How about:

1. Ventilation

Place your generator outdoors, and never in a garage or enclosed area.

2. Use quality cables

Only use heavy-duty extension cords rated for generator use.

3. Keep dry

Generators must be kept dry to prevent electrocution.

4. Limit fuel storage

Store fuel safely away from the generator, letting it cool to avoid fires.

5. Regular maintenance

Follow the manufacturer’s guidelines for maintenance, including oil changes and spark plug replacements, to keep the generator running smoothly and safely.
