In what order should protective grounds be removed from a line?

The correct approach for removing protective grounds from a line is to do so in reverse order to the way they were installed. This practice is crucial for ensuring safety during maintenance work on power lines. By removing the grounds in reverse order, the worker prevents accidental re-energizing of the line while still being safeguarded by the remaining grounds.

Typically, protective grounds are installed to provide a safe path for fault currents and to protect workers from electric shock. If they were to be removed in the same order they were installed, there could be a moment when a worker might be exposed to live components without adequate grounding. Therefore, following a reverse order guarantees that grounding remains in place until the last possible moment, significantly reducing the risk of electrical hazards.

The other options do not provide the necessary safety measures: removing them in random order lacks a systematic approach, while considering removal as soon as the work is completed does not account for any potential residual hazards that may remain immediately after work is done. Following a defined sequence enhances safety and ensures proper protocol is adhered to in potentially dangerous work environments.
