d. The installer has the option of installing eltuu or the local grounding electrode or both. conductor is true? a. A grounding electrode conductor smaller than 6 AWG must be protected by instal- 9. Which of the following statements about the installation of the grounding electrode lation in a conduit or cable armor. b. A sizes are too fragile. grounding electrode grounding electrode. grounding electrode conductor smaller than 6 AWG is not permitted, as such is the minimum-size grounding electrode conductor to a ground ring inimum-size grounding electrode conductor to a concrete-encased

Explanation / Answer

the grounding-electrode conductor cannot be smaller than 2 AWG copper.it is used to size the grounding-electrode conductor where a metal water pipe is the grounding electrode. In addition, the metal water pipe must be supplemented by one or more of the following: the metal frame of a building, a concrete-encased electrode, ground ring, rod, pipe or plate electrodes.

from this we can say 2 AWG is the minimum-size grounding electrode conductor to a concrete-encased grounding electrode.

hence option 'd' is true regarding the installation of the grounding electrode conductor.
