What should always be the first and last connection made when grounding?

• A. Neutral conductor
• B. Ground End
• C. Equipment ground
• D. Power supply

Answer: (B)

The first and last connection made when grounding is the ground end. This practice ensures that the grounding system is properly established before any power is introduced to the system, reducing the risk of electrical shock and equipment damage. By connecting the ground end first, you create a safe path for fault currents and help to stabilize the circuit. Making this connection last when disconnecting ensures that the system is safe before any other disconnections are made, thus protecting personnel from accidental contact with live conductors and maintaining the integrity of the grounding pathway. Grounding is critical in establishing a reliable electrical system, and following this sequence is vital for safety and proper system performance. The other options, while important components of the electrical system, do not serve this specific purpose in grounding procedures.
