What is the focus of maintenance schedules according to the code?

The focus of maintenance schedules according to the National Electrical Code is maximizing equipment longevity. The NEC emphasizes the importance of maintaining electrical systems and equipment to ensure their reliability and safe operation over an extended period. Proper maintenance practices can help identify potential issues before they become serious problems, thereby prolonging the lifespan of the equipment and preventing premature failures.

While minimizing costs, improving installation aesthetics, and controlling installation timing are relevant considerations in the overall management of electrical systems, they do not directly align with the primary goal of maintenance schedules. The NEC prioritizes the safety and operational integrity of electrical systems, which hinges largely on effective maintenance strategies aimed at extending the life and functionality of equipment.
