I REALLY appreciate the input from everyone. I guess I was not familiar with the transfer switch option which sure looks like a quick and easy solution. It is even cheaper than the switch that I purchased that I cannot figure out how to wire. I am starting to thing the switch is faulty!
In regard to this type of auto transfer switch, I have hard-wired Progressive Dynamics Power management system hard wired into the rig where the shore power comes into the rig. Would this trip or send an error message to the Progressive when the transfer switch makes the change. Thanks, Phillip
