Well my friend, I guess you get to take out the patent on the power producing breaker. Or your eyes are as bad as mine and you're really looking at a breaker going across C & A. But that wouldn't explain such an imbalance on the B phase. Did you per chance take your B phase reading with your meter at various positions along the conductor? I also wonder if you might not get a similar reading close by with out your pick up loop around the B conductor.
