What does “live line work” entail?

Live line work specifically involves performing repairs and maintenance on energized power lines. This type of work requires specialized training and techniques, as it is essential to work safely while electricity is still flowing through the lines. Linemen often use insulated tools and wear protective gear to prevent electrical shock while conducting their tasks.

In contrast, the other options describe activities that deal with non-energized lines or safety measures that do not involve directly working on live electrical systems. For instance, working on de-energized power lines, conducting routine inspections of non-operational lines, or setting up safety barriers are all essential tasks, but they do not fall under the definition of live line work, which is focused on active lines carrying electricity.
