Block 11 of AFI Form 487 is dedicated to what aspect of the power system?

Block 11 of AFI Form 487 focuses on the Automatic/Manual Transfer Switch. This is a critical component in electrical power systems that allows for seamless switching between different power sources, such as from the main power supply to a backup generator. The purpose of the transfer switch is to ensure that power supply remains uninterrupted, especially during outages or power failures.

Understanding the automation aspect is crucial, as it allows the system to automatically switch to backup power when the primary source is compromised. Conversely, the manual transfer function provides operators with the ability to intervene and switch power sources as needed, ensuring that control is maintained even in emergency situations.

Knowledge of this block is vital for anyone working in electrical power production, as it directly relates to maintaining a reliable power supply and ensuring operational readiness in various conditions.
