The Benefits of Using a Generac Whole House Generator



Generac whole house generators provide reliable and safe home power in any season. They are available in sizes from 16kW to 22kW, to fit your specific needs. A generator of this size is capable of providing enough power to keep your air conditioner, refrigerator, lights, and other appliances running during an outage. These generators are also frequently used to provide important backup power to medical facilities, which rely on a consistent source of electricity to help care for their patients.

Planning Ahead: Preparing the Space for Your Generator



Installing a Generac whole house generator requires careful planning. Before you start, make sure you have the right fuel supply and exhaust outlets to support the generator. Also, you’ll need to come up with a way to protect it from the elements. Most Generac generators are designed to be installed outdoors, so you should make sure to find a place that is well-ventilated and away from windows or doors. It’s also important to make sure the area is level and free from debris, as uneven ground could interfere with the generator’s operation.

Safety Tips: Working with Electrical Power



It’s important to remember that you should always take safety precautions when working with electricity. Generac recommends that you always use a certified electrician when installing or wiring a generator. It’s also important to remember that you should never attempt to service or repair the generator yourself. Generac provides detailed instructions and diagrams that should be followed when wiring the generator. It’s also important to ensure that you are using the proper gauge of wiring when connecting the generator to your home’s electrical system.

Maintenance: Keeping Your Generac Whole House Generator Running Smoothly

If you notice any issues, you should contact a professional electrician or Generac technician for assistance.

By following the steps outlined above, you can confidently install and safely operate your new generator. With the right wiring diagrams, safety precautions, and regular maintenance, you can enjoy reliable and safe home power for many years to come!
