What does Article 110.36 clarify regarding alteration of electrical installations?

Article 110.36 of the National Electrical Code (NEC) specifically addresses the requirements for alterations to electrical installations. The primary focus is on ensuring that any changes made to existing electrical systems comply with the current NEC standards. This is vital as electrical codes are updated periodically to reflect new safety practices, technologies, and research findings.

By mandating that alterations adhere to the latest standards, the Code helps maintain a high level of safety and performance in electrical installations. This requirement ensures that any modifications do not compromise the integrity of the overall system, and it provides a regulatory framework that protects both current users and future occupants of the facility.

This principle contrasts with the other choices, as changes are not simply encouraged for innovation. Innovations would still need to comply with the standards in place. Approval is a necessary part of the process, especially for significant alterations, and documentation requirements are not typically specified on a quarterly basis in this context. Therefore, the correct choice emphasizes the importance of adhering to current NEC standards when making alterations to electrical installations.
