I have another idea that would take 2 double throw, 2 pole relays and key switches but the logic is too confusing to describe. It would take latching the relays coils by using the load to set the relays. When the machine is off and there is no load, the relays release and the key switches set the power source through the coils of the relays. Extra contacts in the relays can define logic to cancel operation of the opposing key switch until the machine stops or power is cut off to it.
I tried to describe it but lost myself in the logic.
If I get the chance and I can think of a circuit I'll draw out a rough sketch.
One thing that would undo a strategy like this is if the machine has cycles where there is no power drawn. There are time delay contactors that are sold that can overcome this sort of thing. I've found them at Grainger.
Maybe just describing it someone else can figure it out.

Does anyone know a way to feed the electricity from both sides in such a way that if both sides are turned on, the electricity is equally shared, but if either side is shut off at the meter, the electricity automatically shifts to the other side?
Sounds like an exciting project, eh?
