How to Hook Up a Generator to Your House

In times of power outages or emergencies, having a generator can be a true lifesaver. It provides you with a backup source of power, keeping your appliances running smoothly and ensuring your home stays comfortable. If you're looking to hook up a generator to your house, here is a step-by-step guide to help you through the process.

1. Safety First

Before attempting any electrical work, always prioritize safety. Start by familiarizing yourself with the generator's manual and the specific instructions provided by the manufacturer. Make sure you have the necessary safety gear, including gloves, goggles, and non-conductive footwear. Keep in mind that working with electricity can be dangerous and may require professional assistance if you're not comfortable with the process.

2. Decide on the Connection Method

There are two main methods to connect a generator to your house: using an interlock kit or a transfer switch. An interlock kit is a cost-effective solution that allows you to easily switch between your electrical panel's main utility power and generator power. A transfer switch, on the other hand, provides a more professional and seamless transfer between the two sources of power.

3. Assess Your Electrical Panel

To determine the right method for your house, you need to evaluate your electrical panel. Assess the amperage of your panel and its compatibility with the generator. If you have an older panel or insufficient amperage, it may be necessary to upgrade your electrical system for safer and more reliable generator usage.

4. Install the Interlock Kit or Transfer Switch

Once you've chosen the appropriate method, the next step is to install the interlock kit or transfer switch. This typically involves turning off the main power to your house, removing the panel cover, and mounting the kit or switch in a suitable location. Follow the provided instructions carefully, paying attention to electrical connections and grounding requirements.

5. Connect the Generator

After installing the interlock kit or transfer switch, it's time to connect your generator. Start by placing the generator outdoors in a well-ventilated area, away from windows and doors. Use a heavy-duty extension cord to connect the generator to the designated inlet on the interlock kit or transfer switch. Make sure the cord is in good condition, rated for the appropriate wattage, and free from damage.

6. Test the System

Before relying on your generator during an actual power outage, it's crucial to test the system. Start by turning off the main utility power at the electrical panel and then starting your generator. Check if the power is properly transferred to your house by ensuring that the connected appliances and circuits are receiving power. Confirm that the generator is capable of meeting your power needs.

7. Maintain and Refuel Your Generator

To ensure your generator runs smoothly and efficiently, regular maintenance is essential. Familiarize yourself with the recommended maintenance tasks outlined in the generator's manual. These typically include oil changes, filter replacements, and keeping the fuel tank clean. Also, be sure to store sufficient fuel for extended power outages and follow the proper safety protocols when refueling.


Hooking up a generator to your house allows you to maintain power and comfort during unexpected situations. By following the steps outlined here and prioritizing safety, you can successfully set up your generator and help ensure your home remains powered. Remember, electrical work can be complex, so if you're unsure about any step, consult with a professional electrician to ensure a safe and reliable installation. Stay prepared and stay powered up!
