If a person had two small 110VAC generators. Ganged the commons and fed one
generator into each leg of a 220VAC single phase circuit, would it work?
I'm
thinking 220v well pump, small transformer type welder, clothes dryer etc.

If it would work, would the two gen-sets need to be the same size?

There is probably some simple reason why this is a really bad idea, but I
don't have
enough electrical background to see it.

Thanks,

Bill
