I think I understand now. It’s just a hard concept to wrap my head around for some reason. If L1 and L2 are both active, and the load is receiving both voltage sources which are out of phase, then both ends of the load are no longer EEP’s and the load will have current running through it? Sorry about the run on sentence. I just want to make sure I fully understand this. I’m also going to go back and re-watch the video.
