Question 513Electricity/Electronics - Assistant Engineer70% to pass
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?
AI Explanation
The correct answer is C) Connect the common connection to hull ground first, then connect the phase connections to common.
This is the correct procedure because it establishes the ground connection first before making any other connections. Connecting the common to hull ground first ensures there is a proper ground path before the phase connections are made. This helps prevent potential shocks or other electrical hazards. The other options are incorrect because they do not follow the proper sequence of first establishing the ground connection.
