What requirement pertains to nonconductive raceways used in grounding systems?

In grounding systems, the requirement that conductors must be bonded at both ends when using nonconductive raceways is essential for ensuring proper grounding and bonding integrity. This practice minimizes the risk of electrical faults and path interruptions, which can lead to unsafe conditions. By bonding the conductors at both ends, any potential for stray voltage or differential voltage across the raceway is effectively mitigated, thereby enhancing safety and compliance with electrical codes.

Nonconductive raceways, while beneficial for protecting conductors from physical damage and environmental factors, do not provide a conductive path for grounding. Thus, bonding at both ends is crucial to establish a reliable electrical connection, allowing any fault currents to safely dissipate into the ground. This not only adheres to safety protocols but also contributes to the overall performance and reliability of the electrical system.

Other options do not accurately reflect the requirements or characteristics associated with nonconductive raceways in grounding systems. For instance, the idea that they must be regularly replaced or do not require maintenance does not align with the operational principles of grounding systems. Understanding the bonding requirements in this context is fundamental for maintaining a safe and effective grounding system.
