Pardon the spelling error of "transfer" in the subject... not sure how that happened... (how embarrassing)...
Information overload...
So either breaking the ground and neutral (4-pole)OR Not (2-pole) is acceptable?
Ok... what happens if the neutral/ground connection in the generator loosens due to vibration, and the neutral/ground is connected to the grid, a 240V series circuit results sending 240V out onto the grounded conductors... won't this cause a dangerous situation?
Getting back to the "flawed" theory of the oscillating DP Breaker... Is there a central "OFF" position between the two positions? What would such a breaker due assuming an infinitely large current available from both the generator and the grid?
Finally...
Who has the safer connection...me or the miner?
