Site Preparations

The first step in choosing a location for a standby home generator is to decide where the generator will be placed. Generators should be placed on a solid, level base, such as a concrete pad. It should be located in a well-ventilated area, away from windows and doors, to ensure that exhaust fumes are away from living areas. The pad should also be constructed in a way that allows the generator to be easily serviced and maintained.

The generator should also be placed in a way that takes into account any landscaping that might be affected by the installation. If the generator is placed too close to other structures or landscaping, it can cause vibration or noise that may be disruptive. Additionally, the generator should be placed in an area where it can have easy access to its fuel source. This could mean that the generator needs to be placed near a natural gas line or a fuel tank, depending on the fuel type of generator being used. 

Wiring the Generator

Wiring a backup whole home generator requires a transfer switch and wiring to the main service panel. The transfer switch is installed between the generator and the main service panel, allowing for the generator to supply power to the home in the event of a power outage. Wiring from the generator to the transfer switch should be done with conduit to protect it from the elements. The conduit should be securely fastened to the house to prevent water from entering the line.

Once the wiring is connected to the transfer switch, it must then be run to the main service panel. This should be done again using conduit. This will protect the wiring from water and other potential hazards. It is important to ensure the conduit is adequately sized to accommodate all of the wires, as this will ensure proper power delivery. Once the wiring is connected to the service panel, the generator will be ready to provide power to the home.

Fuel Supply

The fuel supply for a whole home generator is an important consideration when selecting a generator for your home. Natural gas from the utility company is a reliable and economical option for many homeowners. Natural gas is readily available and is easy to hook up to the generator. It is also typically the least expensive option, making it an ideal choice for those who want to save money on their fuel costs.

Propane from a tank on the property is another option for those who do not have access to natural gas. Propane offers the advantage of being more cost-efficient, as it burns more efficiently. Propane tanks also require less maintenance and are often easier to install than natural gas. However, they must be regularly refilled, which can be costly and inconvenient. Ultimately, the fuel source you choose will depend on your budget, location, and power needs.

Owner Operations and Maintenance

A backup home generator is an important addition to any home in order to ensure that power can be provided in the case of an outage. Your electrician will go over the entire process of what you need to do after your generator is installed. The generator works by sensing when the power has been cut off and automatically turning on and providing power to the home, there isn’t much to do after the install but enjoy peace of mind. 

In order to keep the generator running properly, routine maintenance should be scheduled. This should include a yearly professional inspection to check for any issues with the generator and to ensure that all parts are functioning correctly. Additionally, a yearly maintenance service plan should be purchased in order to ensure that any repairs or parts replacements needed for the generator are covered. This will help to ensure that the generator runs smoothly and efficiently, providing power to the home in the event of an outage for years to come.


The Generac whole home generator installation process is a straightforward and easy process that can usually be completed in a matter of hours. It begins with a consultation between the customer and the installer to discuss the specific needs for the home and the desired generator size. The generator is then delivered to the home and installed in a safe and secure location. The necessary connections are made to the unit and the fuel supply is hooked up. Finally, the electrical connections are tested and the system is started to ensure it is running correctly. At this point, the generator is ready to provide power to the home in the event of an outage.
