using a dual breaker to give 220V.
is there something about the way its connected that makes the power different ?
Assume the 50 hz vs 60 hz is not an issue.
I have priced a unit that takes 110 input and produces 220 V pure sine output
but would like to avoid the cost if possible.
The device suggested is an inverter to supply a clean 220 V at 50 hz. Its about 500 dollars.
