Basically, I have a 120V device I would like to have powered if either/both of two outlets have power. So both could be on, or just one of them.
The device itself is typical in that it only has one power cord.
How do I wire this correctly? Assuming I have to use these two 120V outlets and a single power cable into the device.
How could this go horribly wrong? Although this may sound absurd, for the sake of my learning, say I "split" the power cable and connected it to each outlet. I assume this would end up providing much more voltage than I wanted and damage the device? I would get some varying voltage based on the phase of each outlet? Or am I horribly confused?
Of course I really need #1 answered, but I'd love some insight on #2.
