I've been getting questions about how to install a back up generator transfer switch. The installation can happen at any time, either at the beginning of a build or home remodel, or it can be added later to provide your home with a back up power option in case of power failure. The switch provides a safe and quick way to transfer the input of power from the utility company to your personal back up generator. Here is a very clear and carefully explained video about how to install the back up generator transfer switch your self. It is made by the 'Reliance' company. I know very little about this company or their products so I am in no way endorsing the product itself. I do appreciate the thorough nature of this video.
