Electrical power configurations, on B777
Hi! Is it possible that, under normal operation, an electrical bus is being powered by two or more other buses at the same time? Or is it always energized from at most one other bus (in case when it is not connected to power source).

on the ground the 777 has "no break power transfer". This means during a power source changeover from say GPU to APU, or APU to engines the sources are paralleled momentarily. This ensures a smooth changover. The feature does not work in the air. As far as memory serves there is no dual source busses....but i'll peruse the books again
