Which of the following is considered an energized line?

Overhead power lines are considered energized lines because they are actively carrying electrical power and pose a direct risk of electrical shock or electrocution to anyone who comes into close proximity without proper precautions. These lines are designed to transmit electricity over distances and are usually found above ground, making them highly visible yet also hazardous.

In contrast, lines that are disconnected from power are no longer energized and thus do not carry any current, eliminating the risk associated with them. Lines being maintained may or may not be energized, depending on whether the utility company has taken safety precautions such as de-energizing them before work begins. Ground wires, typically used to provide a safe path for electrical currents and to prevent surges, are not considered energized since they do not carry active electrical power in normal circumstances.
