What is required after lines and equipment are deenergized before they can be considered dead?

Grounding the lines and equipment after they have been de-energized is a critical safety measure in electrical work. This practice ensures that any residual charges or induced voltages are safely discharged to the ground, thereby reducing the risk of electric shock or accidental re-energization while work is being performed. Grounding serves as an additional layer of protection for workers who may come into contact with the equipment.

Achieving a safe work environment requires more than simply turning off the power; grounding is essential to confirm that the lines are not only de-energized but also incapable of becoming energized unexpectedly. If lines and equipment are simply de-energized without proper grounding, there remains a potential hazard from static electricity or other unforeseen conditions that might cause a line to become energized.

While other measures such as inspections for damage, locking out equipment, and using warning signs are important for overall safety practices, grounding specifically addresses the immediate risks associated with residual power and helps to create a safer working environment for those involved.
