Is it true that a No. 6 GEC exposed to physical damage requires metal covering or protection?

A No. 6 GEC (Grounding Electrode Conductor) that is exposed to potential physical damage indeed necessitates the installation of metal covering or protection. This requirement is in place to ensure the safety and integrity of the grounding system. By implementing metal covering, the conductor is safeguarded against impacts, abrasions, and other forms of damage that could compromise its ability to effectively ground electrical systems. The protective metal covering acts as a barrier that helps maintain the performance of the grounding system, which is critical for preventing electrical hazards, including shock and equipment failure.

The necessity of protection is rooted in electrical codes and standards designed to ensure safe electrical installations. The degree of protection needed can vary depending on the specific environment or situation, but in this case, a straightforward requirement for physical damage scenarios clearly aligns with the safety philosophy endorsed by regulatory guidelines. Therefore, the correct answer affirms the importance of safeguarding grounding conductors from potential physical threats.
