I am hanging line arrays as part of an install, and will be splitting the power evenly over the three phases. The audio processing rack is on the opposite side of the stage from the breaker panel for the speakers. However, there is another breaker panel on the processing rack side. Is there any reason to run a line from the speaker panel over to the rack instead of using the rack side panel? (Other than convenience of having all audio breakers in one place) Pros or cons?
