I too was a little unclear on the two separate power sources AND two separate loads that can never run at the same time. Can they run at the same time as long as each one is on a different power source? If not, why not? Is this a power issue or is it a safety issue?

A double throw safety switch is simple enough to switch loads so that your power source only feeds one or the other but not both at the same time. The only caveat is to look at the HP rating of the switch, not the Amp rating, they may be different. But then again if you NEVER EVER switch under load, which seems unlikely, then it really wouldn't matter as long as you have the amps covered.
