In addition to high voltage circuit grounding with ground-connecting switching devices, for additional operator safety and confidence, portable grounding straps may be used. What is the proper procedure for connecting these portable grounding straps?

Correct Answer: Option C — Connect the common connection to hull ground first, then connect the phase connections to common.

Portable grounding straps must connect to the hull ground first, then to the phase conductors. This sequence ensures the operator remains protected by an established earth path before touching any potentially energized conductor, adhering strictly to IEEE 45 and marine high-voltage safety procedures.
