Hi All,
My question relates to the Quattro with 2 AC inputs, during the transfer from one AC source to another (Grid to Generator) what is the interlock operation performed (mechanical or electrical or both) that prevents AC in 1 and AC in 2 from both being connected at the same time, even if it is very momentary? More specifically, during the change-over, is it a Break Before Make operation that prevents back-feeding of the generator to the grid if the grid has failed?
