When completing repairs on a high voltage circuit where portable grounding straps were used for increased operator safety and confidence, what is the proper procedure for disconnecting these grounding straps?

Correct Answer: Option B — Disconnect the phase connections to common first, then disconnect the common connection to hull ground.

When removing temporary high voltage grounds, the phase connections must be disconnected from the conductors first, followed by the hull ground connection. This reverse sequence maintains continuous zero-potential protection for the technician throughout the final stages of the disassembly process.
