Is there a device that will automatically switch between two AC inputs to send power to one AC output? (quick delay during switching is ok)
Here is an example of that I am looking for...
A device with INPUT A from one source and INPUT B from another (maybe different sides of the circuit braker panel possibly opposite phases.
If inputs A and B both have power, output C would only get power from input A.
If input A loses power, output C would switch over to power from input B.
I would never want any power to connect between A and B because that could cause a short of feedback and that would be dangerous.
As an added note, if power does switch over to B, it doesn't have to return to A if both have power but should switch back to A if B loses power. Basically, get me power from A or B and I don't care how that switch happens as long as it is automatic. It is ok of there is a fraction of a second delay during the switch over as I am only trying to control lighting or devices that won't be damaged by a trivial power loss.
