10 Easy Steps on How to Install a Standby Generator
Step 1: Choosing the Right Generator

Selecting the appropriate standby generator for your home is crucial for ensuring it meets your power needs during an outage. Start by calculating your household’s total wattage requirements, which involves adding up the wattage of each appliance you wish to power, such as refrigerators, heating systems, and essential electronics. Consider the starting and running wattage of these devices, as some appliances require more energy to start than to run continuously.
Once you have a clear understanding of your wattage requirements, research various generator models to find one that can handle your load. Look for generators with features such as automatic transfer switches (ATS) that seamlessly switch power during an outage, fuel options that suit your needs (like natural gas or propane), and quiet operation modes if you are concerned about noise levels. Additionally, consider the generator’s durability, warranty, and support services from the manufacturer. Choosing the right generator is the cornerstone of an effective standby power system, ensuring you have reliable energy when needed.
Step 2: Preparing the Installation Site
Before installing your standby generator, it is vital to prepare the site. Choose a location at least five feet away from any doors, windows, or vents to prevent carbon monoxide from entering your home.
The area should be well-drained and have adequate space for airflow, as most generators require ventilation during operation. Ensure the ground is level and clear of debris, rocks, or vegetation that may interfere with the generator’s operations. If you are installing a gas-powered generator, also consider the placement of the gas line, ensuring it is accessible and follows all local codes about fuel supply.
Step 3: Installing the Generator Mount Pad

If your standby generator requires a mounting pad, carefully follow the manufacturer’s guidelines to install it. Typically, you will need to dig out a flat, level area slightly larger than the generator’s footprint. Pour and level a concrete mix or use a prefabricated pad designed for this purpose. Allow sufficient curing time if using concrete, adhering to the manufacturer’s specifications to ensure a stable base that can support the generator’s weight.
Step 4: Setting Up the Transfer Switch
The transfer switch is a critical component that connects your home’s electrical system to the generator. Begin by locating a suitable installation point for the transfer switch, often near your main electrical panel.
Shut off power to the main panel before installation to ensure safety. Follow the manufacturer’s instructions to connect the transfer switch to the primary electrical panel, ensuring all wiring is done conservatively and securely. Depending on local codes, you might need an electrician to complete this step safely. Once the switch is installed, it will allow for seamless power transfer once the generator is activated.
Step 5: Connecting the Generator to the Transfer Switch
Once the transfer switch is installed, the next step is to connect your generator to it. Start by running the appropriate gauge electrical cable from the generator outlet to the transfer switch securing wiring according to local codes and regulations. Ensure the connections are tight and insulated to prevent any electrical hazards. Follow the manufacturer’s wiring schematic carefully and perform all connections in a dry, shock-free environment. It’s crucial for both safety and proper generator operation.
Step 6: Installing the Fuel Supply

Connecting a fuel line is essential for gas-powered generators. If you use natural gas, install a shut-off valve within easy reach and connect the line to the generator. Ensure that you use the appropriate fittings and follow local codes for gas installation, as improper connections can lead to leaks. Conduct a thorough inspection to ensure no gas leaks and all connections are secured. Do not smoke or use open flames during this process as a safety precaution.
Step 7: Grounding the Generator
Proper grounding of your standby generator is vital for safety and performance. Install a grounding rod according to local codes, ensuring it is deep enough in the ground to provide a stable connection. Connect a grounding wire from the generator’s grounding terminal to the grounding rod, ensuring a secure and tight connection. This step helps to prevent any electrical issues arising from surges or faults during operation.
Step 8: Connecting the Battery
Many standby generators come equipped with an automatic start feature, requiring a battery for operation. Follow the manufacturer’s instructions to size and connect the battery to the generator properly. Ensure that the battery terminals are clean and securely connected to avoid any operating issues. Recharge and maintain the battery per the manufacturer’s guidelines to ensure reliable operation during power outages. Try to run the generator for short periods regularly to keep the battery charged and prevent any potential problems.
Step 9: Testing the System
After everything is installed and connected, it is time to test your system. Turn off the main power supply to simulate a power outage, and then start your generator according to the manufacturer’s instructions. Observe the automatic transfer switch to confirm it properly transfers power to your home. Make sure all connected appliances and systems run as expected. This step is crucial for ensuring your installation is complete and functioning correctly.
Step 10: Regular Maintenance

Maintaining your standby generator is essential for long-term performance and reliability. Follow the manufacturer’s guidelines for routine checks, including oil changes, air filter replacements, and battery maintenance.
Regularly test the generator under load and inspect for signs of wear or damage. Keeping your generator well-maintained ensures that you have a dependable power source whenever you need it, providing peace of mind during unexpected outages.
By following these steps and properly installing your standby generator, you can rest assured that you will have a reliable and efficient backup power source for your home.
