Thanks, David -- that definitely points me in the right direction. Tripplite does still make them: http://smile.amazon.com/Tripp-Lite-PDUMH15AT-Metered-Horizontal/dp/B000MNBWW0/ref=sr_1_3?ie=UTF8&qid=1417047300&sr=8-3&keywords=auto+transfer+switch+pdu
That's the cheapest one they have, and at nearly $300 a little more than I want to spend. However, I also found this: http://smile.amazon.com/Tripp-Lite-PDUB15-100-127V-Horizontal/dp/B003HLUDC4/ref=sr_1_1?ie=UTF8&qid=1417047382&sr=8-1&keywords=pdu+manual+transfer For $150, that's a manual transfer switch. I can leave it running off the UPS (because the UPS is already and automatic transfer switch), and if power fails, I can have the second input source be the generator-powered wall outlet. I can just turn the knob to switch to generator, and back when power is restored. It's a *little* more than I wanted to spend, but not a whole lot, so this may do the trick. I'll keep poking, but I like this idea. -Adam On Wed, Nov 26, 2014 at 7:06 PM, David Nolan <[email protected]> wrote: > You can get a dual input PDU that will auto switch between sources, > connect one input to the ups, the other to a generator circuit.
