How to Connect an Auto Start Generator to Your House: A Comprehensive Guide

Connecting an auto start generator to your house is a significant task that requires careful planning, proper equipment, and adherence to local codes and regulations. This guide will walk you through the essential steps, emphasizing the importance of professional assistance from a licensed electrician.

Understanding Your Load Requirements

The first step in connecting an auto start generator to your house is determining your load requirements. This involves identifying the electrical devices and circuits you want to power, such as lighting, major appliances, HVAC systems, and critical medical equipment. Knowing the total wattage of these devices will help you choose the appropriate size generator.

Choosing the Right Fuel and Placement

Next, decide on the fuel source for your generator. Most people opt for natural gas because it is readily available and requires less maintenance. Propane is another common option, especially for those who already have a propane tank. The placement of the generator is crucial; it should be situated at least 5 feet away from windows, doors, and air intakes to minimize the risk of carbon monoxide (CO) buildup.

Permits and Regulations

Permits and inspections are mandatory steps before installing your generator. Contact your local authorities to obtain the necessary permits. The generator must comply with local codes and meet all insurance requirements. Additionally, ensure that you have the appropriate documentation, such as manufacturer’s installation guides and safety instructions.

Installation and Wiring

Physical installation of the generator should be performed by a licensed electrician. This involves connecting the generator to an automatic transfer switch (ATS) and running the necessary wiring. The ATS functions as an intermediary between the generator and your house’s electrical system. It must be installed upstream of your main breaker panel, potentially necessitating modifications to your existing electrical setup. For instance, the ground and neutral buses may need to be separated.

Local utility companies must pull your power meter at a predetermined time when the inspector is available. This process typically involves disconnecting the service entrance cables, connecting them to the ATS, and having the ATS switch to the generator power. The final inspection and reinstallation of the meter will complete the process.

Connecting the Generator to the Transfer Switch

Once the electrical components are installed and inspected, the next step is to connect the generator to the transfer switch. This is usually done using a gen cord, and the generator should be started outside. Using the access box, switch the main breakers to the generator source, and then gradually turn on the circuits you wish to power.

Professional Help is Essential

Given the complexities involved, it is strongly recommended to hire a licensed electrician. They have the expertise and experience to ensure that your generator is installed safely and meets all local regulations. Attempting to install the generator yourself without proper knowledge and training can lead to severe safety issues and legal complications.

Conclusion

Connecting an auto start generator to your house is a task that demands careful planning, proper equipment, and adherence to local codes and regulations. By following the steps outlined in this guide and involving a professional electrician, you can ensure a safe and efficient installation process. Remember, the well-being of your family and property is paramount, making the right setup a worthwhile investment.
