For equipment operating at nominal voltages of 1,000V or less, what may be required while energized?

In the context of equipment operating at nominal voltages of 1,000 volts or less, all the listed activities—inspections, adjustments, and servicing or maintenance—may indeed be required while the equipment is energized, provided that specific safety protocols are followed. The National Electrical Code emphasizes the importance of ensuring that such tasks are performed safely to prevent electric shock and other hazards.

Inspections can be necessary to verify the proper functionality and safety of electrical systems. Adjustments may be required to maintain optimal performance or compliance with operational standards. Servicing or maintenance can involve tasks that, in some situations, must be carried out while the equipment is still energized to either keep operations running smoothly or to meet urgent safety demands.

However, it is critical that any such activities be performed by qualified personnel who adhere strictly to relevant safety standards and practices. This ensures that the risk of electrical accidents is minimized while achieving compliance with the NEC’s stipulations regarding working on energized equipment. The inclusion of all these activities under the circumstances clarifies the broad scope of potential actions permissible—contingent on safety measures—while dealing with equipment operating at these voltages.
