Within 2 feet of the grounding down conductor, consistent AWG size should be used to the MRPLPR.

• A. True
• B. False
• C. Not specified
• D. Not required

Answer: (A)

Keeping a uniform AWG size in the section within 2 feet of the grounding down conductor to the MRPLPR is about ensuring a continuous, low-impedance grounding path. If the conductor size changes in this critical stretch, the impedance can jump at the transition, causing uneven fault-current distribution and potentially delaying protective devices from clearing a fault or causing localized heating. Using the same gauge here preserves the designed fault-current-carrying capacity and the mechanical reliability of the connection, helping to maintain a solid path to ground under fault conditions. This is why the guideline specifies a consistent AWG size in that near-connection segment.
