What does "live line work" entail?

"Live line work" specifically refers to the tasks performed on energized electrical lines while they are still carrying current. This type of work is critical in maintaining and repairing essential power infrastructure without shutting down the electrical supply, which can be crucial for minimization of outages and ensuring continuous service for consumers and businesses.

Workers performing live line work must be trained in specialized techniques and safety protocols to protect themselves from the dangers associated with working on active electrical systems. These safety measures include using appropriate personal protective equipment, employing proper tools designed for live line tasks, and often utilizing methods such as hot stick work or rubber glove techniques to prevent electrical shock.

The other options, while relevant to electrical work, describe practices that are not categorized as live line work. Working on de-energized lines ensures safety for workers, residential lighting systems installation doesn’t typically involve energized lines, and developing new techniques for safer installations refers more to innovation in electrical work rather than direct interaction with live systems.
