What does the term “hot line work” refer to?

The term “hot line work” specifically refers to performing tasks on live electrical lines without de-energizing them. This practice is crucial in maintaining service continuity for customers and minimizing downtime when repairs or upgrades are necessary. Hot line work is typically carried out using specialized tools and protective equipment to ensure the safety of linemen while they work in proximity to live wires. This type of work requires extensive training and adheres to strict safety protocols, as it poses significant risks if not performed correctly.

The other choices provide context that does not accurately capture the essence of “hot line work.” For instance, working on electrical lines after they are energized could imply a broader range of tasks than what is specifically done while the lines are alive, and using non-electrical tools near power lines does not involve any interaction with the live electrical system. Inspections performed on disconnected lines are fundamentally different as well, focusing on non-live conditions for safety assessments.
