When grounding two separately derived systems, how should the grounding electrode conductors be connected?

• A. Using a single tap
• B. Independently without a common method
• C. In series to minimize length
• D. Using approved connection methods to a common conductor

Answer: (D)

When grounding two separately derived systems, it is essential to connect the grounding electrode conductors using approved connection methods to a common conductor. This approach ensures that both systems are effectively grounded and helps to maintain a consistent ground potential. By connecting to a common conductor, it allows for better coordination of the grounding systems and minimizes the risk of ground loops or potential differences that could arise from separate grounding systems. It also aligns with safety protocols and electrical codes that aim to provide a reliable grounding path, thereby enhancing the overall safety of the electrical installation.
