68. As shown in figure «B» of the illustration, after the high voltage circuit has been properly de-energized and isolated, and tested for the absence of voltage, what is the proper sequence for grounding high voltage motor terminals prior to commencing work

High-voltage motor terminals must be grounded by first connecting the common ground connection to the ship's common hull ground, followed by connecting the individual motor terminals. This sequence ensures a secure ground path exists before connecting to conductors, mitigating the risk of exposure to induced or accidental voltage.
