What does Article 110.38 require for strategies regarding maintenance of electrical equipment?

Article 110.38 of the National Electrical Code emphasizes the importance of scheduled maintenance for electrical equipment to ensure ongoing safety and reliability. This requirement is rooted in the understanding that electrical equipment can deteriorate over time due to various factors such as environmental conditions, wear and tear, and operational stress. Scheduled maintenance allows for systematic checks and repairs, minimizing the risk of unexpected failures or hazardous conditions that could arise from neglected equipment.

Implementing a maintenance schedule helps ensure that all electrical components are regularly inspected, tested, and maintained according to their specific needs, which can vary based on the equipment's design, usage, and environment. This proactive approach promotes safety, extends the lifespan of the electrical systems, and helps organizations comply with safety regulations and standards.

In contrast, other options involve less rigorous or more reactive maintenance strategies that do not align with the intent of Article 110.38. Ad-hoc maintenance based solely on visual inspections lacks the thoroughness required for safety, while annual reviews without a specific schedule may result in inconsistencies. Maintenance performed only during installations does not address the ongoing needs of the equipment after it is operational.
