Where should a grounding bar be placed on the pole?

A grounding bar should be placed below the lineman's feet to ensure safety while working on a pole. This placement allows for effective grounding of the pole structure and minimizes the risk of electrical shock for the lineman. By positioning the grounding bar below where a lineman would be standing or working, it provides a direct path for any fault currents to safely dissipate into the ground. This is particularly important in preventing dangerous voltage levels during maintenance or repair work.

Grounding bars need to be strategically located to facilitate a swift and safe grounding method, ensuring that any accidental contact with live wires does not lead to a hazardous situation. The lower placement also makes it accessible for proper connections to be made without the need to reach higher up, which could also pose safety risks.

In contrast, other placements such as at the top, midpoint, or above the transformer may not provide the same level of safety and effectiveness in grounding. Such locations could increase the risk of exposure to high-voltage areas and complicate access for linemen during operations. Thus, positioning the grounding bar below the lineman's feet is crucial for maintaining safety protocols in electrical work on utility poles.
