Generally, the grounding electrode conductor shall be ___ without a splice or joint.

Generally, the grounding electrode conductor shall be ___ without a splice or joint.

• A. installed in one continuous length
• B. formed into a ground ring
• C. made of copper
• D. rated as necessary

Answer: (A)

The conducting path that bonds the electrical system to the earth must stay as a single, unbroken piece from the grounding electrode to the service equipment. Keeping the grounding electrode conductor in one continuous length ensures a low and predictable impedance to fault current and minimizes points where corrosion, loosening, or physical damage could raise resistance or break the path. When a splice or joint is introduced, those weak points can fail or corrode over time, compromising the effectiveness of grounding. That’s why the best choice is installing the grounding conductor in one continuous length. The other options don’t match the requirement: forming into a ground ring isn’t the general rule for the conductor’s continuity, copper is a material choice but not a necessity stated by this requirement, and being “rated as necessary” doesn’t address maintaining a continuous, low-impedance path.
