I have been told that if the line connects breaker to breaker, it is considered to be radial; but, this doesn't make sense to me. If a line is connected by two feeders then there would be two sources of power, hence "Radial". I'm not sure if I'm missing some minute detail that makes the whole issue clear itself, or if I'm simply being overly dense. Admittedly, circuit diagrams have always given me pause, even after having spent enough hours studying them to make a preacher cuss. Again, I'm not sure that I'm not trying to get to my thumb through my elbow. I have attached an image of what I'm talking about.
