The "sequence of events" was i replaced a 3 Phase RTU blower motor, same as old one, and added a motor starter. I needed to reverse the direction so i just picked any two phases and reversed. The starter tripped out. I took my amp probe and found the amps on each phase were way out of wack. Like 5-2.5-0 on each of the 3 phases. I then reversed things back and used the other phase. Guess what all 3 phases even out and no tripping overload.
I don't understand it completely myself and maybe wolfdog can explan it in more detail.
