I do have an option for you but none of our power transfer switches will allow you to switch between three AC power sources. However, I do have a way for you to do this but you will need to install two power transfer switches like the Go Power Automatic Transfer Switch part # 34264403 for example. A transfer switch will have a single dominate side. So how the input is wired into the switch will affect how it passes power through, so two switches could be wired using the attached photo
