The ________ of manufacture and the _______ of the installation of the fusible links shall be marked on the system inspection tag.

• A. Year and Date
• B. Date and Year
• C. Manufacture and Installation
• D. Year and Serial Number

Answer: (A)

The main idea is that the system inspection tag must record two dates: the year the fusible links were manufactured and the date they were installed. This pairing gives a clear history of the component’s age and when it began service, which is essential for maintenance planning.

Knowing the year of manufacture shows how old the fusible links are, which matters because aging and material degradation can affect performance. Recording the date of installation tells you when the system started operating, so technicians can calculate how long the links have been in service. Together, these dates help determine whether replacement or inspection intervals have been met and ensure the system remains reliable.

Other date combinations don’t provide the same complete picture. Simply noting a generic date or excluding the installation time would make it harder to assess service life or trace the history of the component.
