Short sections of Farris metal raceway used for physical protection of the grounding electrode conductor shall be bonded at both ends to the ______.

The correct answer is that short sections of Farris metal raceway used for physical protection of the grounding electrode conductor shall be bonded at both ends to the grounding electrode conductor. This is crucial for ensuring a complete and effective path for fault currents, thereby enhancing the safety of the electrical system.

Bonding the metal raceway to the grounding electrode conductor helps to maintain the integrity of the grounding system. It ensures that any fault current that may occur within the system can flow back to the earth without encountering resistance that could lead to dangerous voltage levels or potential hazards. Additionally, ensuring that the raceway is bonded to the grounding electrode conductor maintains continuity and reliability of the grounding system, preventing issues related to improper grounding that could affect equipment function or safety.

While bonding to other components like ground, service equipment, or neutral conductor may have its own benefits in certain contexts, the primary purpose here focuses specifically on creating a reliable connection for the grounding electrode conductor, which is key to effective grounding and safety in electrical installations.
