What must be removed before reenergizing lines or equipment at a point of disconnection?

• A. All safety barriers
• B. All power sources
• C. All protective grounds
• D. All warning signs

Answer: (C)

Before reenergizing lines or equipment at a point of disconnection, it is crucial to remove all protective grounds. Protective grounds are implemented to ensure safety by providing a low-resistance path for fault current to minimize the risk of electric shock or equipment damage. They serve as a final safeguard while maintenance or repair work is being conducted. Removing protective grounds ensures that the equipment or lines can be safely energized without risk to personnel still in the vicinity. If protective grounds remain in place, reenergizing could create an unsafe environment, as they may inadvertently connect parts of the system, leading to hazardous conditions. By prioritizing the removal of these protective grounds before reenergizing, it helps maintain a safe working environment and prevents accidents related to electrical faults.
