Box supply tripped again at the circuit breaker in the service panel (no fault at the box supply). With the approval of Sarin Philip we embarked upon a bold new plan of action. Paul Powers, Jim Coleman and I completed LOTO of the supply, we then attached the Fluke Power Analyzer to the input of the supply. Since the breaker was tripping due to a ground fault, Paul re-adjusted the ground the fault from 240 amps to a maximum setting of 1200 amps.
