Good for testing. Not legal to have any custom circuits not going through the main breaker in competition. The millivolts across the breaker is very close to the current passing through it in amperes.
I found that putting a good sized digital voltmeter display on an open PDB port and visible during test driving goes a long way toward understanding the electrical dynamics of your machine. Panel mount meters are 5 or 6 dollars. Seeing the meter drop into single digit range is eye opening indeed. I know the guys were working on coding that withheld the shot motor if the compressor was running after they saw the system voltage drop when it started.
