Find the Answer
Answer: B
Article 682 applies to the installation of electrical wiring for natural or artificially made bodies of water not covered by other Articles in the Code. Under normal circumstances, a 14 AWG (copper) equipment grounding conductor would be acceptable as per Sec. 250.122. However, as specifically noted in Sec. 682.31(A), the EGC shall not be smaller than 12 AWG.
