Is the use of separate grounds for elbow-type bucket trucks with insulated sections acceptable?

The correct choice indicates that the use of separate grounds for elbow-type bucket trucks with insulated sections is acceptable. This practice enhances safety by providing a dedicated ground path that helps reduce the risk of electrical faults or inadvertent energization while working on or near live systems. Insulated sections are designed to protect workers from electrical hazards, and having a separate grounding system ensures that if a fault occurs, it does not pose a danger to personnel in the bucket truck.

Establishing separate grounds can also improve system performance, particularly in reducing the potential for step and touch voltage exposure when working on overhead lines or equipment. This practice aligns with safety standards and best practices for electrical work, ensuring the protection of workers while they are operating bucket trucks in environments where energized lines are present or adjacent.

In contrast, the other choices imply restrictions that may not be necessary or could lead to less safe operational practices. The idea that separate grounds should only be used in emergencies or at the direction of a supervisor does not recognize the proactive approach that safety protocols advocate for in normal operational circumstances.
